Help with 508 - Ls and Is look thick

- I create my document in InDesign and export (not print!) to PDF. The PDF looks great.

- I go through and tag images, background, add alt text, etc. and save my file.

- All the Ls and Is in my document look thick! I checked to make sure my setting about reducing thin lines in Acrobate is unchecked and it is not checked.

This could be a mismatch with your monitor's screen resolution, which is very common.

• With the PDF open in Acrobat, what happens to the Ls and Is when you zoom in, such as to 100%, 200%, or closer? Do they still look thick?
• Try adjusting the resolution of your screen, or move the PDF's window to a second monitor if you have one. How do they look?
• And if you print out the file, do they look ok, or still thicker?

- I go through and tag images, background, add alt text, etc. and save my file.

On another note, why aren't you doing these tasks in InDesign, before you export the PDF? Then  you wouldn't have to do these tasks in Acrobat, which is a painfully slow workflow.

It might be worth a try, once you see the issue, to change your magnification.  If it's a screen drawing issue, changing magnification would force a screen redraw.  Sounds overly simple, but I've seen it before.  Does this anomaly show up if you open the PDf on another machine?  Saving, closing, and re-opening?  Any more details you can provide could be helpful.

My best,

Have you tried choosing another font to see if the problem persists? This may help you to determine if it's the font or something else. Also, you may want to try turning off ligatures in InDesign to see if that's the issue.
