PDF spreads from InDesign: radio button vs dropdown

May 18, 2021 Leave a comment

When proofing PDFs of books to clients, it is often important that the client sees the proof as a series of left and right page spreads. PDFs made with any of InDesign’s default settings (these are the options in the Export Adobe PDF dialog box in the top dropdown field in square brackets) will show the PDF in Adobe Acrobat as it’s default view – single pages.

Adobe Acrobat does allow for pages to be presented in two-page appearance, but this is controlled by the user. If the user is unaware of this feature, then they will be viewing the PDF using Acrobat’s default single page view.

It is possible to change the view settings of a specific PDF while in Adobe Acrobat and this is done from the Properties option from the File menu.

The page viewing defaults of Acrobat itself can also be changed, but this will view any PDF that has not had its preferences changed when the PDF was made.

It is worth noting though that prior to 2015, the widely accepted method to prepare a PDF as readers spreads was to do this from InDesign’s Spreads radio button in the Export Adobe PDF dialog box.

While this does prepare what appears to be readers spreads, it does so with some disadvantages:

  • The centre spread line cannot be seen. This can be addressed by using the page border script from Indiscripts that applies a page border to all pages. Run this script prior to exporting the PDF to generate the page border and then export the PDF, then rerun the script to turn the border off.
  • The page count is incorrect. The folios will still appear to be correct within the PDF, but the page navigation itself will show the page count as half the number of original pages plus one (e.g. a 16pp file saved as spreads will now show up as 9pp in the PDF’s navigation).

However, from June 2015 it has been possible to set the default view options when exporting a PDF from InDesign for viewing in Adobe Acrobat.

This allows PDFs to contain the correct page count and to also show the page split between the spreads while still showing the pages as spreads.

Should be problem solved, right?

Unfortunately, no. Despite the dropdown now being available, there’s no ideal way to prepare readers spreads to suit all PDF readers or platforms.

  • Unless InDesign users read all of InDesign’s patch notes (maintained by James Wamser) or were otherwise made aware of this change, then normal habits would persist, and users would continue to prepare spreads using the spreads radio button.
  • If the dropdowns had been used, this only makes viewing the spreads possible in Adobe Acrobat (Reader or Pro), but unfortunately this software is no longer the preferred option for viewing PDFs. Besides Mozilla Firefox and Adobe Acrobat, most PDF readers only support single page view.
  • Even if Acrobat or Firefox are being used, users can still override the view either manually, or using Acrobat it can be done by default using accessibility in the preferences

So what can be done?

There are effectively four options:

First option is to prepare PDFs based on an audience using Acrobat only as their reader and use the dropdown option for spreads. If the PDF is exported from InDesign using a PDF/X standard, Acrobat will also show the PDF as it appears in InDesign’s overprint preview.

Second option is to prepare a PDF using the pre-2015 method of using the spreads button and the Indiscripts page border script.

Third option is to lobby the manufacturers of the non-Adobe PDF reader software to bring their software into line with the PDF specifications set out by Adobe itself (and while they are doing that, also update their readers to also accept form fields and commenting functions!).

Last option is to do nothing and leave the pages as single spreads… and that isn’t necessarily a bad option. If the PDF is being created for onscreen viewing only, and the viewer must see something that is intentionally spread over two pages such as an image that crosses over two pages, then single pages should be fine.

Last word

It is of note that people are not just consuming information on a single desktop monitor, but may have two or more monitors in which software windows are being juggled around; or on a mobile device that is more natural to be held in a portrait fashion. Social media apps such as TikTok and Instagram are designed for mobile devices to be held in a portrait orientation. It’s hard for me to admit, but left and right hand pages are just a legacy of printed books as their assembly creates this phenomenon. Unless there is a crossover between the two pages, a reader will usually read the content on one page, adjust their gaze and read another – their focus of vision can’t be on both pages at the same time.

Also, if the PDF is intended for print by a printing company, don’t provide them a PDF as readers spreads as they won’t be able to impose the pages for printing without breaking the PDF back into single pages.

Export many PDFs at once… plus security

March 8, 2021 Leave a comment

A recent question on Reddit’s InDesign subreddit was whether two PDFs could be exported at the same time from the same document, but have two different properties – one with trims and one without. The answer is yes, but via a custom script written for the task.

I use such a script on a daily basis so that I can prepare a PDF for client proofing via email; and a separate PDF that has trim and crops that is sent directly to a hot-folder that prints it for me.

I’d submitted my script as a solution (that can be downloaded from the scripts page), but then realised that this concept was not a new idea. Ariel Walden over at ID-Extras had already written a similar script within a blog post of his own.

Similarly, Peter Kahrel’s Batch Convert script can perform the same task, with the added advantage that it can also do this for all open InDesign documents;

Or if no documents are open, a specified folder (and subfolders if desired) of InDesign files.

Can’t make these secure

One feature that all three scripts have in common is that the exports are based on the PDF presets available on the user’s machine. One feature that can’t be added to a PDF preset is security – this can only be done when a request to export the document is made, as security settings aren’t saved into PDF presets.

This is a problem if there are lots of documents that need to be exported with security settings as it requires the user to enter the security details each time a PDF is exported.

I’ve made an additional script

For this purpose, I thought I would make a script that not only makes several PDFs, but can also add password security to one version. The script can be downloaded from the scripts page.

When the script is run, it will generate two PDFs using different PDF export settings, but one will have the suffix “_secure” added to the filename, and a dialog box will appear once the export is finished:

Adjustability

The script can also be adjusted by opening the script in any text editing application and making the necessary changes, such as.

Use the same password for every document

Look for the line

    openDocumentPassword = myPassOpen; // requires a password to open the document

and change the myPassOpen to the desired password in quotations. For example:

    openDocumentPassword = "OpenSesame"; // requires a password to open the document

Similarly, do the same thing for the line underneath, making sure that the open password and edit password are not the same.

    changeSecurityPassword = myPassWrite; // requires a password to change the document

change to

    changeSecurityPassword = "EditSesame"; // requires a password to change the document

then search for the lines

dialog.show();
//alert("Done");

and swap the forward slashes in the lines around so that the lines now read like this.

//dialog.show();
alert("Done");

Only require a password to edit the document

Look for the following line:

    openDocumentPassword = myPassOpen; // requires a password to open the document

and add two forward slashes to the start of the line.

//    openDocumentPassword = myPassOpen; // requires a password to open the document

Adding two forward slashes to a line in a javascript tells the script to ignore the rest of the line and go to the next line of code.

Don’t show the “done” message

The default script has a dialog at the end for showing what the opening and editing passwords are, but if you want to edit the script so it makes a PDF that applies security to edit the document but does not provide the password (e.g. for the purpose of handing PDFs over to parties who may seek to deconstruct them in other applications) then make the adjustment mentioned a moment ago to restrict passwording to editing only, and then search for the lines

dialog.show();
//alert("Done");

and swap the forward slashes in the lines around so that the lines now read like this.

//dialog.show();
alert("Done");

Add more PDF exports

Look for the line

app.activeDocument.exportFile(ExportFormat.pdfType, File(resultsFolder + "/" + app.activeDocument.name.split(".indd")[0] + ".pdf"), false, "[High Quality Print]");

make a copy of the line and make the appropriate changes:

  • Replace the “[High Quality Print]” to the desired PDF preset exactly as it is written in the PDF export dialog box and put it in quotes. For example, if your PDF preset is called My Export then type “My Export”
  • Replace the “.pdf” with a suffix that denotes that this is an additional PDF. For example, if the pdf is a high res print, perhaps replace this with “_hi-res.pdf” so that the resulting file has _hi-res.pdf at the end of its filename.

Otherwise if you are after specific changes to the script to suit your needs, contact me via the contact page.

Things to know about the script

Opening and editing passwords must be different

One condition of preparing a secure PDF from Adobe InDesign is that the password required to open the PDF must be different to the password to edit the PDF, so if editing the script to replace the randomly generated password to a known one, the opening and editing passwords must be different. If the passwords are the same, the PDF will be made without security.

PDF Standard in the preset must be set to “None”

PDFs that use a PDFX standards can’t have security applied to them as the security panel of the PDF export box is greyed out, preventing security to be applied. The standards dropdown box in the desired PDF preset must be set to None.

Only password security is applied

When exporting a PDF from InDesign, only password security can be applied, unlike Adobe Acrobat’s choices of security that it can offer (as shown below).

While password security may deter or prevent a layperson from editing the PDF, the security can be broken through some effort. Several websites offer services where users can drag and drop a PDF to the site, and within moments the PDF will have the PDF password removed.

Similarly, there are desktop applications that can also be purchased to remove the security (as one of their many features), such as PDFsam Visual.

Outlining the problem… text outlining

February 15, 2021 Leave a comment

From time to time, I will prepare PDF artwork for third party providers and then note that their specifications indicate “Convert all text to outlines” (also known as converting to curves or paths). But why do some third parties recommend this practice?

The PDF is opened in software other than Acrobat

For commercial printers, PDFs are usually imported into Raster Image Processing (RIP) software that will impose and trap the artwork for their printing methods. However, not all providers work this way and may need to open the PDF in applications other than Adobe Acrobat. For example, a third party that prepares cutting formes may open the file in Corel Draw or a CAD application that supports its CNC software.

This means that as the file opens, the application may ask for fonts not available to the third party.

This can be exacerbated if the PDF is opened not only in a different application than Adobe Acrobat, but also a different alphabet and writing system. Converting the type to outlines maintains the appearance of the type without requiring the font to be present.

Other reasons that text is converted to outlines

So special effects can be applied

InDesign, Illustrator and Photoshop can apply interesting special effects to vector objects, but not all of those effects can be applied to live type. The solution is to convert the type to outlines, thus converting the type to vector shapes that can have the desired effect applied.

To prevent editing by third parties

Limited editing is possible within PDFs using either Acrobat’s own editing tools or using plugins such as Enfocus Pitstop Professional. These tools can allow last minute alterations to text so long as the text is type and not converted to outlines.

Locking the PDF with password protection isn’t an option as this can prevent the file from being placed into layout software or RIP software for output, so the password is then required to unlock the file. PDF password protection is also somewhat breakable, with many websites offering services where PDFs can be uploaded, and then unlocked and then downloaded without the password protection. There are also PDF editing and viewing applications such as PDF Sam that allow for decryption of PDFs.

Even without the Enfocus Pitstop plug-in, it is possible to open PDFs in Adobe Illustrator or Affinity Publisher and then – if the fonts are available – make the necessary alterations… though converting type to outlines will prevent this.

To circumvent the font EULA

A client may have acquired a font that has allowed for screen use only and prohibits embedding in a PDF, preventing the font from appearing correctly in the PDF. A way around this is to convert the type to outlines in the native application prior to PDF export, though it is worth noting that the End User Licence Agreement (EULA) of the font may forbid this workaround, so it is worth reading the font EULA.

That doesn’t mean it should be done!

There are issues that arise from converting type to outlines. Dov Isaacs – Principal Scientist for Adobe Systems – has a brilliant PDF that details this (and much more) but the basic takeaways concerning type to outlines are:

  • Increased filesize that takes forever to download or view onscreen
  • Smaller typefaces do not render as well
  • May potentially breach the font’s EULA

In addition, there are other issues such as:

  • Potential issues with fonts where type overlaps itself (it can knock out holes in the joins)
  • If the conversion from type to outlines has been done in the native application and then accidentally saved and closed, this means the type will no longer be live in the native application.
  • It can prevent or hinder minor type alterations being made in a PDF submitted for print.
  • Text (as outlines) that has special effects applied (as described earlier) may not always be able to have the same effect applied to live type. This can create issues with variable data campaigns where the effect needs to be applied to a text variable.
  • It can make it difficult to identify the font used, as the font’s information is no longer in the PDF and the only other way to identify the font is visually or with apps such as what the font, adobe capture, or identifont.
  • The conversion is usually a one-way conversion. There is a fantastic Adobe Illustrator plug-in from Astute Graphics called Vector First Aid 2 that – in some circumstances – can convert outlines back to type, but it isn’t a magic bullet (though definitely worth a look).

If your hand is forced…

In a perfect world, I’d only deal with providers that fully supported PDF/X-4 files. Unfortunately, not all providers do, and occasionally our hands will be forced into providing PDFs specifically as the provider has requested, which may mean converting text to outlines. Rather than doing this in the native application (e.g. InDesign or Illustrator) there is a great way to quickly convert all type to outlines using an Adobe Acrobat Preflight that is detailed over at CreativePro.

Small tips to save big time

August 2, 2020 Leave a comment

I often find it interesting to watch the different ways that my colleagues and I may perform the same task. Take the InDesign command Paste in Place for example. I’ll typically use the keyboard shortcut, but I’ve noticed that one colleague will go to the edit menu and select it from there; another will right-click and access it through the contextual menu, while another has an ergonomic mouse that has the shortcut hot-keyed to an additional button (No-one used InDesign’s quick apply panel).

While there are many ways to accomplish the same task, they all take different amounts of time and hand travel. A two-handed keyboard shortcut takes less time than navigating through the menus and – if using a mouse – leaves the cursor in its last position; but takes one hand off of the mouse briefly. In my situation, I’m using a Wacom tablet, so after using a keyboard shortcut, I then have to reposition the cursor as I’m usually still holding the stylus in my right hand. I’m also not a fan of the gymnastics my hands have to often do to in order to execute a task, and recently I’ve been hot-keying eight of my commonly used shortcuts to the contextual menu of my stylus.

Luckily in the Paste in Place example, there is more than one way to accomplish the task, and there’s no right way to use this – it is whatever is most comfortable for the user. What I would like to highlight in today’s article is how to accomplish common tasks more efficiently.

It is worth pointing out that this isn’t an exhaustive list and doesn’t get into details that might require the purchase of dedicated software such as Digital Asset Management software, or the creation of hot folders from software such as EFI Fiery Command Workstation, but is a few tips that anyone of any skill level can take advantage of to save a minute here and there from their workflows.

Within InDesign

Add your own interface items

The option to edit Keyboard Shortcuts and Menus can be found from the Edit menu

Keyboard Shortcuts (KBSC)

From the keyboard shortcuts menu, it is possible to assign keyboard shortcuts to items that do not have shortcuts assigned by default, as well as redefine shortcuts from the defaults. Shortcuts can also extend to scripts in the scripts panel as well.

Add own menu items

It is possible to make your own set of menu items using InDesign’s own menu customisation, but this only allows users to create their own menu sets based on the default set – you can’t make your own new items… without scripting. Indiscript’s Marc Autret has an article where he explains an overview of how this can be done, and provides examples as well.

Add own contextual menu items

Adding the Draw Measurement Arrows script to the contextual menu.

Silicon Publishing’s Ole Kvern wrote an article about making a contextual menu startup script that adds functionality to the contextual menu available via the right mouse button. However, I’ve since added my own functionality based on his script by editing the script in a text editor and adding my own items.

Improve on viewing the current items

Customise workspaces

Does every tool need to be visible or docked all at once? Perhaps consider making workspaces more appropriate to the workspace that is actually being used. InDesign ships with some defaults that behave this way, but it is worth experimenting.

Using Bart van de Wiele’s CreativePro 2020 tip to make a custom links palette separate to the usual links palette.

An extreme (and clever) example was demonstrated at the CreativePro 2020 Online Conference by Adobe’s Bart van de Wiele. In the 3 minutes max session, he demonstrated a way of customising the Links palette and saving it as its own workspace – allowing more information about a link to be viewed briefly, and then navigating back to the regular workspace.

Improvement on the scripts panel

Peter Kahrel’s runscript user interface

InDesign’s default script panel literally mirrors how the scripts are filed in finder/explorer, but is missing many features such as a search facility and could really use an overhaul, given its appearance hasn’t changed since InDesign was released. Luckily, Peter Kahrel has made his own launcher that allows scripts to be filtered by name.

Within any application

Not all tips are specific to Adobe InDesign. One Adobe application in particular – Adobe Acrobat – has long been criticised for its lack of customisation, so any opportunity to improve its use is appreciated.

Better navigation

Use dictation

For users that hunt and peck the keys rather than touch-typing, it is worth considering using the real-time dictation features in Mac and Windows operating systems (and some specific software) as word recognition is on par with typing speeds up to 90 words per minute or more.

Learn the new OS features

Each time the operating system is updated, it is worth paying attention to the changes made by the platform for any time-saving features. One example from my own circumstances is using spotlight to access applications rather than the dock.

Default Folder X

I was introduced to this paid Mac plug-in from St Clair Software several years ago and I’ve been using it since. It extends the functionality of save as dialogs which provides recent folders, open folders and favorites.

Controller specific shortcuts

While keyboard shortcuts were mentioned earlier in the article, it is worth noting that they can usually be applied as buttons to controllers that are beyond the usual two-button mice that can be found in an office.

Wacom Stylus

The default radial menu accessed via the Wacom Desktop Center

I’ve used the base-model stylus for years. In addition to the buttons on the stylus, there are four more buttons on the tablet; and the ability to call upon a contextual menu with one of the stylus buttons that allows more tasks to be carried out.

Gaming mice

Mapping custom keys to the Logitech G300S gaming mouse.

I was introduced to this tip once again at CreativePro 2020 online, and it seemed like such a simple idea that I’d wondered why it hadn’t been implemented in my workplace. For example, a base-model gaming mouse such as the Logitech G300S has nine programmable buttons.

Touch portal

A simulated appearance of an iPad using sideshowfx’s Photoshop shortcuts via Touch Portal.

Long-known to live-stream performers on Twitch and Youtube is a product called the Elgato Streamdeck. Put simply, it is an additional keyboard that is customizable to quickly access shortcuts via one button instead of the keyboard gymnastics that can come with some keyboard shortcuts.

A cheaper alternative is software called Touch Portal, and this turns a smartphone or tablet into a streamdeck-like device – ideal for anyone who has an old smartphone or tablet that isn’t otherwise in daily use. The free version is limited to two screens with eight icons each, but a paid version is offered with far more extensibility at a price that is affordable for any pocket.

While this does require its own customisation, SideShowFX has boxed up a collection of Photoshop, Illustrator, After Effects and Premiere shortcuts that are ready to install. Their youtube page has a great explanation of how it all works.

Have it your way

Ultimately, these are solutions that I find helpful, but I like to keep an open mind to new techniques and strategies to get my work done efficiently and accurately. If you have any techniques or strategies you would like to share, please leave a comment or get in touch directly via the contact page.

Referencing pages of a multi-page PDF file during data merge… workaround

August 31, 2019 Leave a comment

At the time of writing, there are three multi-page/artboard file formats that Adobe InDesign can import when placing a file via the File/Place function. These formats are:

  • PDF
  • Adobe Illustrator
  • Adobe InDesign

(While it is possible to create many artboards in Adobe Photoshop, it is not possible to import a specific Photoshop artboard into Adobe InDesign… – at the time of writing that is – but that is another article!)

When placing one of these three formats, it is possible to control several import functions using the show import dialog box, such as:

  • Which page (or pages) to import;
  • How the pages should be cropped;
  • Whether or not to place the pages with a transparent background; and
  • What layers to show and their visibility;

However, when importing these file types as variable images during a data merge, these options are unavailable and replaced with the following:

  • Only the first absolute page of the file is imported (not always the page numbered 1 as the first page can also be – for example – in roman numerals or start at a page other than one); and
  • Page cropping, transparency and layer visibility is determined by the same variables as the last file of that type to be placed into the artwork.

For now, there is no workaround to control the latter issues during a data merge, other than to be familiar with this behaviour and plan the merge accordingly. There is a workaround for importing pages beyond the first page of a PDF file… but not an Illustrator or InDesign file.

Workaround: Split the PDF

The term “workaround” is used loosely in this context. Unfortunately, the solution is to break the PDFs into single page records. This can be done within Acrobat using the split button from the organise pages panel.

This feature also allows multiple files to be split at once.

By default, the resulting files will maintain the same filename with the addition of _Partx prior to the filename, with x representing the absolute page number.

Otherwise, I’ve prepared an action that you can download here that will save the PDFs to the Documents folder of the machine running the action.

(Yes, I’m also aware that there are quite literally hundreds of websites out there that will split multi-page PDFs to single PDFs for free. However, the methods outlined above will do so without involving a third party).

The next part of the workaround involves the data itself, and I’ll be using Microsoft Excel to create formulas to make the numbering for the resulting pages. All variable images being referenced will also be in the same folder as the data file, meaning only the filename is required and not the full path and the filename.

For data where the page number is known

Add a column to the database that references the absolute PDF page number that needs to be imported.

Absolute vs Section numbers abridged:

Absolute numbers refers to a page number based on the total count of pages in the document, while section numbers refers to the page number that was applied using page numbering in the application that made the PDF.

For example, take a PDF that contains 20 pages with the first six pages being in roman numerals, and the remainder being in decimal numbers. These two different styles of numbering are section numbers, while absolute page numbers refer to the total count of pages. To reference page iv of the PDF, the absolute page number to reference is 4. To reference page 5 of the PDF, the absolute page number reference is 11.

In this example, the A column represents the PDF to reference, the B column represents the absolute page number, and C represents the result. To obtain this result, the following formula can be used:

=SUBSTITUTE(A2,".PDF","_Part"&B2&".pdf")

This formula will look at filename reference and substitute the .PDF portion of the filename for _Partx.pdf, where x represents the figure in the B column. Using this formula, only filenames with the PDF extension will be affected, while filenames in other formats will be unaffected.

For data where the page reference needs to increment by one more than the row above

The same formula can be used for the naming, but another formula is used to determine if the page reference should increase if the same base file is being referenced in the row directly above.

In this example, the N column represents the PDF to reference, the O column represents the absolute page number, and P represents the result. A 24 page file NS91912 is being merged and needs to have the page reference incremented by one so that the filenames are NS91912_Part1.pdf to NS91912_Part24.pdf. The following formula can be used to change the page reference:

=IF(N2=N1,O1+1,1)

This formula will look at the filename and determine that if the filename is different to the row above, put the number 1 in the cell, BUT if the filename is the same as the row above, take the page value from the cell above and add 1 to it into this cell.

In a perfect world

Again, this is a workaround – it will only work for PDFs and requires some upfront work to prepare. Ideally, if I had my way and could implement some improvements, I’d like to see:

  • Not just the ability to choose a specific page, but choose the correct trim box and layers as well. For example, a file reference such as myFile.pdf;1,trim;Layer1,Layer2 where 1 represents the absolute page number, trim represents what trim box to use, and Layer1,Layer2 represent the layers I would like to appear (or leave the layer bit blank if all layers should be visible).
  • The ability to perform a similar task for incoming INDD, AI or PSD files.

Add date selectors to date fields in interactive PDF

June 29, 2019 2 Comments

A feature of Acrobat DC that can be quite handy is the prepare form feature. It allows a scan (or a document with no form-field elements) to have form-field elements applied to it, so long as the formatting of the artwork follows the practices listed in this document.

However, there is an improvement that I feel could be made to this feature, but may have been missed by the Acrobat team, and that is date fields. Take the following example:

Now run the Prepare Form feature of Adobe Acrobat DC Professional:

The signature is picked up OK, but the date field is just a text field.

After doing a little digging online, I found that changing the name of the Date field to something like Date_af_date (the importance being the _af_date text) and this will change it to a date field;

But it doesn’t truly act like a date field. If I close out of preview mode and tab to the text field, it behaves like a regular text field.

It isn’t until the format category is changed to date that the field behaves like a date field with a date picker.

So that’s fine to edit one field, but if there are lots of date fields to edit, or this is a regular task, it can be time consuming. Ultimately, I’d like Acrobat’s prepare form feature to detect the date fields just like other fields like text inputs and signature fields are auto detected.

Until that happens, I’ve created an Acrobat action that will run not just the prepare form feature, but also a javascript that will find any of the resulting fields that have the word Date (case-sensitive) in them and make them selectable date fields. That action can be downloaded here.

To change the date format, open up the Acrobat action and change the following line in the script:

The number in brackets can be changed from 5 to a value between 0-13 that represents a format as shown below:

0: m/d
1: m/d/yy
2: mm/dd/yy
3: mm/yy
4: d-mmm
5: d-mmm-yy
6: dd-mmm-yy
7: yy-mm-dd
8: mmm-yy
9: mmmm-yy
10: mmm d, yyyy
11: mmmm d, yyyy
12: m/d/yy h:MM tt
13: m/d/yy HH:MM

In the meantime, if you would like the Acrobat team to update the prepare form feature so that date fields are automatically detected, I’ve added it to the Acrobat Uservoice wishlist.

Extract an Image from an image field in an Acrobat Form

February 17, 2019 Leave a comment

In January 2017, Acrobat DC added two new buttons to the prepare form panel in Adobe Acrobat DC: Add Image and Add Date:

eximage01

The Add Image button creates a rectangle that – when clicked in Adobe Acrobat Pro or Reader DC – launches Finder (Mac) or Explorer (Windows) to navigate to an image to be inserted into that field.

To demonstrate this, I have created a business card order form in Adobe InDesign for a Travel Agency.

eximage02

Note that I have not made the image field in Adobe InDesign. There is a good reason for this: it isn’t possible at the time of writing the article as the option doesn’t exist in the buttons and forms panel in Adobe InDesign.

eximage03

While this is frustrating, it can be added in Adobe Acrobat. I’ll leave a link to the indesign uservoice feature request to hopefully have this (and the add date button) added in future (ignore that the Adobe Staff says its fixed at the time of writing – I disagree).

For now, I’ll export this file as an interactive PDF and add the add image button to the artwork.

eximage04

I can then close out of preview and look at the form. This should be fine for testing purposes.

eximage05

For the purposes of prototyping this form, I’ll type some dummy data and use a stock photo from Adobe Stock.

eximage06

Fields all look fine, the text can be extracted by either cutting and pasting into my InDesign card template, or using the export option from the Prepare Form tools. While the image isn’t juxtaposed correctly, I can do that once I extract the image from the PDF… or at least I thought.

The image won’t extract

If I go to the Edit PDF tools of Acrobat, the image (and its field) cannot be selected.

eximage07

The image isn’t shown as an attachment in the attachments tab.

eximage08

If I use the Export all as images from the Export PDF tab, will that work?

eximage09

No, it only exports the images of the beer bottles and the Eiffel Tower shown in the original card.

How about if I use the Edit Object tools, right click on the image and select “edit image”? Unfortunately, this is unavailable too.

eximage10

Using the Enfocus Pitstop Professional Plug-in, can I extract the image this way? No!

eximage11

Yes, I could zoom in and take a screen capture, or render the PDF in Adobe Photoshop, but neither will retrieve the image to the exact resolution the original image was supplied. Looking at this particular image, if I zoom in at 3200%, it is quite a high resolution image.

eximage12

At this point, I turned to the internet for help, only to find the following thread on the Adobe Forums that contained a response from an Adobe Staff Member that read as follows:

eximage13

To me, this is bizarre… the whole purpose of adding an image would be to remove it later for another purpose, especially since the form field doesn’t have any cropping, scaling or rotating options. The whole point of me making this form was so that:

  • the client didn’t need the full version of acrobat to add the image as an attachment to the PDF;
  • the client Didn’t need to send the PDF and the image separately;
  • I could receive one file to prepare the content of the business cards, rather than bits and pieces from various emails or downloads.

However, all is not lost!

There is a way

Create a new InDesign file and place the filled in interactive PDF as an image.

Export the file as a print PDF using the [High Quality Print] setting with the following change to the compression panel:

Now, when the PDF opens in Adobe Acrobat Professional DC, I’m able to use the Print Production Tools to click on the image and then select Edit Image.

Once the image opens into Photoshop, I can see it is the same size as the original.

So yes, it is possible to extract an image from the Image Field of a PDF, but it takes a little work. I’m just frustrated why the Acrobat Team made it difficult “by design”.

Lastly, if anyone from the Acrobat Team is reading this going “he’s having a go at us again”, rest assured, I will be praising the team in an upcoming post.

How NOT to make annotations in a PDF

July 23, 2016 1 Comment

In early July, I prepared a video for my employer that demonstrated how to mark up a PDF correctly, primarily how to use the commenting tools. This came about as a direct result of the Adobe Acrobat team removing certain icons from the comment panel, meaning that many of my customers had to be re-trained on how to mark-up PDF proofs that they were sent. Since July 12, the Acrobat team has decided to return one of the icons it had removed from the comment panel, but still pushes for the use of the blue arrow tool to make additions, deletions or replacements of text. I’m happy that the icon has returned, but frustrated that it was removed in the first place.

This is important because PDF mark-ups can use the annotations workflow that works like this – simple comments are taken into Acrobat using the comments tool and then imported directly into InDesign using plug-in software available from DTPtools. Here is a link to a video of the workflow in action – it effectively takes the mark-ups that were made in the Acrobat file into the ID file, and these mark-ups can be accepted or rejected in a similar fashion to revisions made in Microsoft Word.

There will be occasions that alterations outside of the scope of the annotations workflow will have to be made, but I would encourage anyone who has been asked to mark-up a PDF for their printer to please read these suggestions:

Use the Adobe Acrobat Reader

Yes it is possible to mark-up a PDF in other software such as Preview (Mac) or in some browser plug-ins, but for the mark-ups to save and be interpreted correctly by the DTPtools annotations plug-in, please use the Adobe Acrobat Reader.

Mark-ups only please

That being said, please do not:

  • attempt to make the changes live in the PDF, but instead use the commenting tools only. This means staying clear of the typewriter tool and only using commenting tools, namely the blue arrow tool to make deletions, additions or replacements (or use the classic icons); highlight or sticky note.
  • open the file in Microsoft Word and save it back as a PDF. This can make it impossible to tell the distinction between the two files and will result in the artwork being set up again from scratch.
  • print the PDF and then mark it up in pen, scan it to a new PDF – this will quite clearly not work with the annotations workflow.
  • add or delete pages from the PDF. If pages need to be deleted, use the mark-ups to indicate this. Likewise, if pages need to be inserted, use the sticky-note tool to inform the operator that pages need to be inserted.

Good instructions

  • Delays and misunderstandings because of unclear instructions = $. This will result in a new proof that will no doubt contain misunderstood edits will need to be corrected, resulting in further proofs, chargeable time, delays and frustration.
  • Make sure your instructions are so clear that edits are easily understandable by anybody. Even if you have had a conversation with someone about the alterations to be made, never assume that the person making the alterations will be the person you had a conversation with.

When working in groups

  • Make a distinction between comments intended for collaborators and authors; and comments intended for a printer. Collaborators generally know what is being referred to, but prepress staff are making changes only, so make sure that the instructions for the printers are easily understandable. Any notes, such as opinions (e.g. I don’t like that font), or topic specific queries (e.g. need to fact-check this statement) really should be between collaborators and authors.
  • “Duelling banjos”. If collaborators can’t agree on specific alterations, don’t take it out on the prepress operator – they are doing what they are told to do in the PDF. If there is a dispute between authors about what does/does not need to appear in the publication, resolve that prior to submitting the PDF to the prepress operator for changes.
  • When collaborating, make sure each collaborator is either looking at the SAME PDF, or the same COPY of the PDF, and that changes are submitted at the same time rather than staggered. There is a great video that specifically deals with collaborating groups here.

Think about the practical application of the mark-ups

  • Have realistic expectations of the edits. For example, supplying a 5 page word file with the instructions “fit on 1 page” is unrealistic.
  • Understand the implications of changes. For example, pages that are designed to work as readers’ spreads will be jeopardised if an instruction to shuffle pages forces the spread to break… a segue to this issue…
  • Shuffling pages… Again this can be quite confusing, especially if LOTS of pages are being shuffled around. Remember that shuffling pages can also break pages that are meant to appear together, such as pages set up as readers spreads. Make sure that the new order of the pages is clear to avoid any confusion.

Ultimately, a well marked-up PDF proof can result in more reliable changes being made faster and on-time.

Now you see it, now you don’t… why?

Several posts ago I wrote a piece concerning Acrobat XI and its ability to undock the comments panel so that it could be moved away from the right hand side of the screen. This had advantages when scrolling the list of comments, as to get to the comments further down the list you have to use the slider (that can sometimes miss comments if scrolled too far) or single-click the arrow at the bottom of the scrollbar, and this can inadvertently:

  • Invoke my Dock to pop up on my mac;
  • Invoke a “hot corner” action on my mac that is set to the bottom right of the screen;
  • Inadvertently open an email alert that pops up via Microsoft Outlook (alerts pop up on the bottom right of the screen).

Read the full article here.

The solution was to click on a button within the commenting panel that would allow the list to be undocked. Here is how it used to look in Acrobat XI:

trackalts2However, in Acrobat DC, the “Undock Comment List” is no more!

There is no ability to change this in the Commenting Preferences either.

This might seem like a rather obscure feature, but when working with marked-up PDFs as a workflow it is a handy feature to have that will save lots of time.

Fortunately, the ability to view comments that were unchecked does remain… for now!

However, I am less than impressed so far with Acrobat DC, and this is largely due to the way it was released. When the product was made live via Creative Cloud, Acrobat DC appeared as an upgrade, but what wasn’t apparent is that uninstalled the existing version of Acrobat! Luckily there were other users that experienced this before me and had tweeted about it:

taketh3For most users, this may not have been a problem, but my version of Acrobat was also running a paid plug-in and had several scripts that had modified the user interface menus, such as the ability to reverse the page order or collate another PDF into the currently opened PDF. So installing Acrobat DC would have completely deleted these enhancements, and meant putting them back on… and in the case of the plug-in, would have meant purchasing the new version (there was no free update to work with Acrobat DC), and waiting until it was available!

To be fair to Adobe, they have now amended the installation process and introduced a checkbox that is ticked on by default that says “Remove old versions”. I’m glad we’re now given a warning and an option, however I think the default of that option should be ticked OFF.

That said, Adobe have received the message loud and clear not to do it again. I say that as an attendee of the PEPCON 2015 Conference in Philadelphia, where attendees met the Adobe InDesign engineers on day three for a general questions and answers session, where this (and many other suggestions) were passed directly onto the team.

Unfortunately, it came a little too late for the find font panel in CC2015. Mike Rankin at indesignsecrets.com posted this piece on the sudden disappearance of icons in the find font menu of Adobe InDesign that many in prepress find invaluable.

See it at the final size… finally!

Two previous Colecandoo articles (part one and part two) discussed the inability of InDesign to control the view size and appearance of PDFs that were exported using the Adobe PDF export function from the file menu.

Since the June release of Adobe InDesign CC 2015, this is no longer an issue. As part of the PDF export dialog box, a new “viewing” portion has been added to the interface that allows for the view size and the layout.

exportpdf1It is worth noting though that the compatibility dropdown of the PDF export options must be set to Acrobat 6 (PDF 1.5) before this feature will fully display all options in the layout dropdown field. If the compatibility dropdown is set to Acrobat 5 (PDF 1.4) or lower, then two of the layout options – Two-Up (Facing) and Two-Up (Cover Page) – will be greyed out.

exportpdf2It is great that this feature has been added to the PDF export interface. Let us see if future releases of InDesign CC can also incorporate other PDF export features such as:

  • Ability to create and export PDF comments directly in an InDesign file; and
  • More support for PDF forms.

Just to find fault however, I have noticed that the Pages portion of the PDF export Dialog box has NOT incorporated a change that was made to the print dialog box, and that was the inclusion of the option for “current page”.

2015-07-03 NOTE: This article is now out of date since the release of Adobe InDesign CC 2015. However, I have left the article here for posterity.

A previous Colecandoo article presented a way of being able to control the view size and page presentation of PDFs used as soft-proofs for clients. The solution was to use the Actions tool in Adobe Acrobat to apply an appropriate action that contains the necessary view size/page presentation settings.

This method certainly works, but there is a far more easy method that can be done directly from Adobe InDesign, and that is to export as an interactive PDF.

As a printer that, I had created very little interactive content until recently. I felt that the “Export to Interactive PDF” was only of use for content that contained form fields or other interactive elements, so I had not considered this an option… until now. In fact, this method is much easier than the method described in the previous article. Once again though, this should only be used when a client is checking the content of the PDF only.

To do this, select File/Export (or command + e on a Mac) and from the dialog box, select Adobe PDF (Interactive) from the dropdown list and click Save.

interpic01

A new dialog box will appear showing the available options for export, including the view and layout settings.

interpic02

If preparing a proof that is to appear as readers spreads, be careful that it is possible to select the same view in two places in this dialog box, with some unwanted consequences.

interpic03

To avoid this, use the Two-Up (Cover Page) option available from the Layout dropdown menu, rather than the Spreads option from the Pages/Spreads radio buttons.

The method still needs improvement…

One important note is that unlike the PDF export option for print, there is no way to save export presets for Interactive PDFs. Instead, the options used to last export an interactive PDF are maintained for the next export.

With this in mind, PDFs can also be exported en masse using Peter Kahrel’s batch convert script, but make sure that prior to using the script, one file is correctly exported to interactive PDF before using the script. Peter’s instructions do say this already, but it is worth writing it again.
