I have a typeface family that is designed to be stacked using layers. The designs are of different sizes (eg. one font will be the uncountered outline, another will be just the counters). Although I design them all to align nicely in Glyphs, when they end up in other bits of software (Illustrator, Affinity Designer), some of the letters are out of alignment. I am aware that different companies use different standards to decide how the alignment happens (I think I did something with a single pixel at the top of the d for Adobe shizz, but cannot remember now, due to age-related memory loss), I wondered if any of you clever people could point me towards any reading material on this matter, as it all a bit “talk to the hand” with the various software companies. Many Thanks
Illustrator uses the height of the lowercase d by default to determine the line height, but there might be other factors at play here. Could you post a screenshot of some of the misalignment? (Or send them to us in a private message; click profile picture → Message.)
