I recall seeing an Adobe online publication some while ago that was devoted to accessibility in InDesign. Of course, I can't find it again. Does anyone have a link?
Here is some info:
I believe this is the old PDF you might be referring to:
Accessibility is more complex than what you'll learn from an online reference, even mine.
Example, my live online class is 16 hours long and I wish I had about 4 more for my students so we can get into some more complex design issues.
But to narrow accessible PDFs down to the essentials:
There are more requirements and accessibility features to meet PDF/UA and WCAG accessibility standards, but these 6 items are the foundation that must be there for all PDFs to be usable and accessible for the majority of users.
I notice that your note seems to refer only to Acrobat, which I sort of understand, I am sort of hoping to do some of the work in InDesign. For instance I have a repeating graphic logo on every page, which should be an artifact. Can I tag and export it as such in InDesign?
With your help, I seem to be in good shape. Many thanks, Bevi
All 6 items listed above are done, preferably, in InDesign and not Acrobat.
Once the PDF file is created, it's too cumbersome to build in all of those features.
So for tags, you specify the PDF tag in the Paragraph Style's definition in the Export Tags section (at the bottom). Choose the most appropriate tag from the drop-down menu.
And yes, repeating logos should be artifacted, and in most publications, everything on the Parent Page (aka, Master Page) as well, which InDesign does automatically.
When the work is done correctly in InDesign, you end up with a very compliant, accessible PDF. Not perfect yet (Adobe hasn't given us all the tools we need nor corrected the bugs), but one that can be quickly polished in Acrobat in minutes.
That's the strategy: do it the right, right from the start in InDesign.
Many thanks Bevi. I'm pretty much doing that by now, as I've beaten a couple of InDesign glitches into submission.
One more question, if you please, the document is massive, 550 pages. I've been noticing my computer laboring a bit under the strain, plus acrobat has a tendency to crash while I'm doing accessibility things, and I'm thinking of exporting from InDesign in 50 page chunks and then running the accessibility check and assembling in acrobat. Would this have any adverse effects on accessibility once the full document is assembled?
Good strategy, but make it easier on yourself <grin>.
Any time the page count goes beyond 100, we consider breaking it into logical sections and use InDesign's Book utility to manage them (and export 1 PDF from all of them, and make one TOC from all of them). You're really asking for problems when one INDD file is 500 pages!
1. Break up the one long INDD file into several. Whatever makes sense, like at chapters or major sections.
2. If it's all threaded together, you might need to use the Break Thread script:
—Window / Utilities / Scripts to bring up the panel.
—In the Community folder, choose BreakTextThread.jsx and follow the instructions.
3. Create a new "book" (File / New / Book) and then drag the individual INDD files in order into the panel.
4. View the Online Helpx for books at https://helpx.adobe.com/indesign/using/creating-book-files.html to learn how to control pagination between the files, export one PDF from the files, and more tasks.
As long as you make one PDF from the book, accessibility should be just fine. Your other method, combining the files individually in Acrobat, is a royal PITA hot mess of work.
Remember, to meet the PDF/UA-1 accessibility standards, you must have a live TOC in any PDF that is 10 pages or longer, as well as Acrobat Bookmarks in the bookmarks panel. You won't get that and their correct hyperlinks if you piece the files together in Acrobat.
So, yes, break it up into smaller sections. Use the Book utility to manage everything.
