Hi people,
I'm usually proofing my typefaces on iPad in addition to printing, but I've always had some chromatic aberration related issues when viewing the fonts in Acrobat Reader or Notability (the latter of which is my preferred proofing-software due to its much better rendering of handwritten notes).
There's a small red-ish and blue-ish lines showing along the edges of the letters. A rather distracting issue when trying to assess the qualities of a font.
Do you know if it's possible to improve the display performance on iPad and get rid of the colored lines around the letters?
If at all relevant: I'm using an iPad Pro from 2020 if memory serves me well (i believe the generation JUST before the M1 ipads).
Thanks!

If this is not an issue in browsers or other software, then it may be the result of Acrobat’s rendering engine (and whatever Notability is using). I am not very familiar with Acrobat on iPad, but on desktop it actually uses three different rasterisers, depending on the size of the text and the format of the font, so depending on zoom level and content a single page in a PDF might be using more than one rasteriser.
Here is where the preference is in the full Acrobat.
Smooth text “for Laptop/LCD screens” is what can cause color fringing. “For monitor” is the grayscale subpixel rendering, more similar to what Apple uses, and the most recent Windows approach. You can also turn it off.
I don't :-)
