Subject: Delete PDF tag vs. artifact?
No previous message | Next message →
Hello,
I am new to tagging. For decorative or irrelevant images, is it always necessary to artifact them? I am testing and find that if I delete the irrelevant tags from the PDF they still display on the PDF but are not spoken by the NVDA screen reader. I am generating PDF tags when I save the MS Word doc to PDF, so as far as I can tell I am not losing my irrelevant images.
Also...when writing alt-text is it preferable to include or exclude the period (stop) at the end of the sentence?
Thanks!

I think it is preferable to artifact decorative content instead of just
removing the tags: otherwise you may end up with "untagged" content when
you use the built-in automated accessibility checker in Acrobat to check
the accessibility of your PDF. And in some cases, it will mean that you
have content in your PDF content tree that is not placed inside a
declared container, which is required by the more extensive PDF/UA
specification for accessible PDFs.
In practical terms, I'm not sure in which cases this will affect a
particular user of assistive technology, but the best practice would be
to artifact these items.
When you delete the tags in the tag editor, you are not deleting them
from the actual content tree, but just from the tag tree, and screen
readers will use the tag tree to present the content if they can.
I'm not sure of the best practice regarding periods at the end of
alternative text. I normally don't. Unless my alternative text contains
more than one sentence - which I try not to do!
Phil.

I am a screen reader user so this is my opinion based on my experience
dealing with PDF documents.
Punctuation is important and in most cases speech synthesizers will
adjust their behaviour depending on the punctuation provided.
A slight pause or change of pitch can occur based on the punctuation
provided. If no punctuation is used, then the text may be run together
with the text contained in other elements of the document.

Regarding punctuation in Alt-text, we discovered eons ago that many (if not all) screen reader technologies would run the Alt-text into the body text that follows if there wasn't punctuation at the end. Without it, there wasn't a clear audible change in the voicing to signal the user that Alt-text had ended.
Since those of us who create content have no idea which A.T. or personal settings will be used to access our I.C.T., it makes sense to put punctuation in our Alt-text, especially at the end, to ensure we're communicating as clearly as possible to our audiences.
It takes just a nanosecond to type a period at the end, and it does absolutely no harm to the document, only good.
Our policy is to always use correct grammar, sentence structure, and punctuation in our Alt-text. We aim to communicate ideas as best as possible to everyone in our audience, and eliminate potential confusion.
