I have always used "Lato Heavy" as a font in PDFs we produce. Since yesterday, this font no longer renders as it used to (in Indesign preview or PDF). The only thing that has changed in the time which this issue has arisen is Creative Cloud updating itself. Some screenshots to illustrate my point:

Last week

this week

I have changed nothing in the indesign file between the two PDFs. The same PDF preset was used for both. Both screenshots were taken at the same level of zoom (66.7%). Interestingly, the issue is not present at 100%. I can understand that some fonts don't render correctly at all levels, but as Lato Heavy always has in the past, I can't think what is causing this.

Any help would be greatly appreciated as this one is causing me to tear my hair out!

  • What software do you use to view the PDF's? – joojaa Oct 25 '16 at 11:38
  • The issue seems to occur in Adobe Reader (11.0.18) but not in Google Chrome's PDF viewer. – tkf247 Dec 5 '16 at 9:26

This really seems like a rendering issue, 66.7% is really a tight percentage for scaling stuff that involves giving a pixel value at the end.

Things that may be causing this artifact:

  • Your PDF viewer has a poor rendering engine.
  • Your ClearType configuration in Windows is not properly set.
  • you've set a broken natural value to the font size at the document (12.5, or even an odd number, some fonts react weirdly to odd font size numbers)
  • you lack or got disabled graphics acceleration for the viewer
  • Thanks for the response Lucas. Further to joojaa's comment above, I tested in different PDF viewers and the issue is present in Adobe Reader but not in Google Chrome's PDF viewer. Could it be an issue with Adobe Reader? – tkf247 Dec 5 '16 at 9:29
