Droplet like it’s hot

February 24, 2019 5 Comments

As a prepress operator, a great deal of my time is spent making sure that artwork supplied by clients will print without any prepress issues. Given that most client-supplied files are PDFs, a great deal of my time is spent in Adobe Acrobat checking the files using the print production tools and an invaluable plug-in called Enfocus Pitstop Professional.

While I’ve given the Adobe Acrobat team plenty of grief over my last few blog posts, I do have to sing their praises over a rather massive feature that – for me at least – has gone unnoticed since its inception in Acrobat 7 – preflight droplets.

What is a droplet?

A droplet acts as a “hot folder” that – once a PDF is dragged onto it – will run a preflight profile on that PDF.

This works for one or many PDFs. I first learned of this feature from this Jean-Claude Tremblay’s post to an InDesignSecrets article about using the preflight feature to convert a file to outlines, rather than using InDesign-based methods. That said, the droplets feature has been available since at least 2007!

Making a droplet is simple. While in the print production panel of Adobe Acrobat, click the preflight button, and in the new dialog box, select Create Droplet… from the Options button.

The next dialog box will ask what preflight profile to use, where success/failed PDFs should be processed to, and if a summary PDF needs to be created of each file.

Many of the built-in preflight profiles either force compliance to one of the PDF/X standards, or analyse a PDF and report the errors that were encountered. However, it is the custom fixup portion that may interest readers in a production role. To see where this can be found, click the Edit Profiles… selection from the Options button of the preflight dialog box.

Underneath the warnings and standards compliance, there is a section titled custom fixups.

In this panel is a plethora of changes that Acrobat can make to an entire document to fix common preflight issues such as:

Faux blacks
White overprint, or other colours that should knockout instead of overprint
Black instead of Registration
Remove trim marks and take back to 3mm bleed
Make pantone spot color names consistent

In addition, it is possible to make your own custom fixups rather than use the built-in ones. Click the add button to add your own fixup.

It is also possible to drill down even further in the editing by clicking additional edit buttons.

This allows for further variables to be made.

Usually, many of these changes would be done using Enfocus Pitstop Professional’s action lists or global changes, but with the creation of an appropriate preflight droplet, not only can they be done without the Enfocus Pitstop Professional plug-in, they can also be done without opening the PDF.

Wouldn’t use it as a catch-all

It would be great to have one preflight that will catch all scenarios and fix the PDFs so that all that needs to be done is make sure the content is right and that the art is fit for its purpose… but because there are so many edge-cases that I deal with, it is more appropriate to make a “catch-most” preflight for common errors such as the ones mentioned earlier.

It can be confusing

With so many options to choose from, it can also be very confusing and – at times – frustrating, especially when some custom fixups contradict each other with no way of being able to sort out what one should go first.

Some of the commands are also not so intuitive. One instruction that I wanted to use – that was to make any object that wasn’t 100% black to knock out – wasn’t where I thought it would be.

It took hours of trial and error to realise that the color range to select was Gray Object (black below 96%) is set to overprint… but who would know with the other options that appear to make more sense?

It’s not a magic bullet

That’s not to imply that the Enfocus Pitstop Professional plug-in isn’t necessary – it is an absolute must for prepress operators. Preflight droplets complement the Enfocus plug-in, saving hours of time manually scanning a PDF looking for “the usual suspects” and allow PDFs in a workflow to be “normalised” for colour profile, trim/bleed size, appropriate overprints and knockouts as required, etc.

There are some fixups that work better using the Enfocus Pitstop plug-in, such as the generate bleed action. When run as a custom fixup via Acrobat preflight, it only adds bleeds to rendered art, and usually by scaling it. The Enfocus pitstop plug-in is more versatile in that it will apply to both vector and raster images, and bleed off appropriate edges only.

Importantly, the preflight fixups won’t be able to make content-related changes, such as fixing typographical errors or moving artwork away from a trim-edge… these changes have to be made with manual intervention using the Enfocus tools.

Lastly, preflight droplets are not a substitute for a skilled prepress operator examining a file, given that droplets cannot:

Ensure that artwork will fold correctly or be suitable for their intended purpose;
Confirm that the artwork is the correct version supplied by the client;
Understand the context of the content such as spelling, grammar or “design features”.

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:

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.

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.

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.

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

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

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.

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

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

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.

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

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.

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:

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.

Checkboxes are back in Acrobat Comments… sort of…

January 11, 2019 3 Comments

Following on from my last post (or rant) about the removal of the checkbox in Adobe Acrobat’s commenting tools, I can report that the December 2018 release of Adobe Acrobat has brought back checkboxes within the commenting tools. However, it does come with some caveats:

It is an “opt-in” preference

Unfortunately, the ability to see checkboxes is off by default. If you are missing the checkboxes and want them back, you have to make sure that you have the following checkbox checked in your preferences:

Checkboxes are only shown when comments are selected

Unlike earlier versions of Acrobat that would show all checkboxes (whether the comment was selected or not) the checkboxes will only appear once a comment is selected.

I find this frustrating as I have to click on the comment to then have access to the checkbox, whereas in previous (admittedly older) versions, the checkboxes always appeared. Kelly Vaughn’s Document Geek site does a fantastic job of showing the different ways comments were handled in previous versions.

However, if all of the comments are selected, then all of the checkboxes become visible.

Problem solved, right? Sadly, no. If any of those checkboxes are clicked, all checkboxes that appear will change state from unchecked to checked.

So while checkboxes can appear in an unchecked state, the UI still has lots of room for improvement when compared to previous versions of Acrobat, or other paid PDF viewers such as Bluebeam Revue. For now, it’s a small win to see the checkboxes return.

The share button can be made smaller

Another UI fixup that was highly requested was the ability to remove the great big share button in the top right. Again, it’s there by default, but you can make it smaller by right clicking next to the button and selecting the Hide Share Button Label option:

So the button won’t go away, but will at least be half the size:

Déjà vu?

Unfortunately, this is the second time in recent years that myself and others had to twist the Acrobat team’s arm to bring back a feature that had been removed (or deprecated), such as the time that key tools from the commenting panel were removed before being reintroduced months later following user complaints.

In this instance, this isn’t the outcome that I (and many other users) were after, but at least it is a step in the right direction. Let’s hope that the next version of Acrobat introduce some of the community’s suggestions about the checkboxes, as well as other pain-points that can be found on the Acrobat Uservoice.

Bring Back the Checkbox in Acrobat Comments

November 28, 2018 1 Comment

UPDATE 2019-01-10: Checkboxes were reintroduced in the December 2018 update of Adobe Acrobat. More information can be found here, but I will keep this article visible for the sake of posterity.

At the beginning of October 2018, Adobe released its updates for Acrobat DC and Acrobat Reader DC. For those users who have the “Automatically install updates” checkbox checked in the Acrobat preferences, the update was installed without prompting.

Unfortunately, as part of this update, the Acrobat team removed a checkbox that is visible in the commenting panel when a comment is selected, as shown in the following image:
By checking the checkbox on or off, it allows the comments to be filtered as checked or unchecked – quite handy when checking mark-ups that can’t be imported directly into InDesign’s new PDF comment import feature.

Strangely, while the checkbox was removed, it is still possible to mark a comment as checked, but this is done by right-clicking on the “Add checkmark” option of the contextual menu.

Thinking this must be a bug, I went onto the Adobe Acrobat forums to see what was going on, only to be astonished that this was not a bug, but an intentional change:

However, I completely disagree with the terms “clean and intuitive to use” and would substitute the terms “ludicrous and mind-boggling“. The idea of a checkmark is to either check it or uncheck it. If it is not possible to check the checkmark because it is not there, to me that is not intuitive, that is frustrating.

In my mind, this user interface change is the equivalent of removing the right indicator signal on a car, and activating the right indicator required changing the radio station twice.

Once I knew the workaround of using the contextual menu to click on the checkbox, I was still frustrated as this triples the amount of work to perform the same task. Instead of a one-step procedure of clicking a check box, the procedure now involves three steps:

right click,
scroll down,
click the Add checkmark option.

This is fine if checking one item as marked, but if checking dozens – if not hundreds of these items – one at a time, that is an inconsiderate inconvenience.

Knowing the keyboard shortcut (Shift + K) is another workaround, but again this requires clicking on the comment(s) and then putting both hands on the keyboard to activate the shortcut.

For long-time readers of the Colecandoo blog, this may come as a sense of déjà vu, and that is because two years ago, a similar problem occurred.

Unlike the previous situation, I happened to be attending Adobe MAX 2018 in Los Angeles when the change had occurred, so was able to pass this feedback directly to the Senior Product Manager of Document Cloud. I took a selfie to prove that we in fact met while at MAX:

To be fair on the Acrobat team, they have changed their stance and now listed the Uservoice issue as a planned one:

However, despite going straight to the top about this issue, and having over 200 complaints to the Acrobat Uservoice page at the time of writing this article, the issue is STILL here.

In short, this is an important issue that many regular Acrobat users would like to see implemented now as a patch, rather than as a roll-back of the feature for the next scheduled release of Acrobat DC. I know the Acrobat team never intends to frustrate users, but keeping users waiting for this change back to be implemented is exacerbating the issue, especially when it was made clear through the Acrobat Uservoice that the change was unpopular.

My last comment on the matter is to those who design the UI/UX for Acrobat. When considering improvements for the software, please ask the users of the software what they would like implemented, and leave features alone if they are already there!
