A rather obscure and never before used checkbox in the export PDF dialog box has caused great concern for one particular reader, and that was the ability to create a PDF that has visible guides and grids.
To illustrate what happens, the following example will be used. Take the front of this flyer for a band, and note the gridlines in InDesign.
The flyer is ready to be sent to the client so a PDF needs to be made. For the purpose of this demonstration, the [High Quality Print] setting that is one of the default presets for Adobe InDesign will be used, with one exception: The checkbox at the bottom “Visible Guides and Grids”
The PDF is now created but unlike other PDFs, the guides and grids are not only visible, but will end up on the final print as well! The illustration shows that the guidelines can be selected with third party tools such as Enfocus Pitstop Professional.
In this reader’s case, the checkbox was clicked mistakenly and fortunately for them, the eagle-eyed prepress staff that were about to print the artwork had noticed the lines and fixed the situation accordingly. However, the issue had highlighted several important points:
- Always check PDFs before submitting them to anyone;
- Always insist on proofs from your printer, whether a hard-copy proof or a soft-copy proof that accurately reflects what will be printed;
- Never, ever, EVER tick the “Visible Guides and Grids” checkbox in the export PDF dialog box!
There are many features of InDesign that are somewhat obscure and would be used rarely, but is there really anyone out there that would ever feel the need to show their clients the grids and columns on a PDF, yet alone output them to a print-ready PDF?
Only instance that comes to mind would be a client that insists items on a proof are not lining up. Using this feature (with the appropriate gridline in the file) would create a PDF that would show the client that in fact the items do line up as intended… but is this a situation that arises often enough to warrant such a button in the export options?
Reader thoughts are definitely welcome on this topic!
It can be handy when circulating an internal proof and you need to show the live image area on an ad or signage.
But have never had cause to show one of these to a client.
This is another compelling reason to set up export presets for all prepress workflows.
