Hi there. This is my first post on Typophile so please excuse me if this topic has been answered elsewhere or if I'm in the wrong place.
My question is about managing kerning across interpolated fonts in FontLab. I have no experience in this area and I am just trying to understand how it is handled.
Say I have a light and a bold. I have kerned both. I then interpolate (using Blend Fonts?) a regular in-between. The regular would have kern values averaging the light and bold.
Where I'm having trouble:
If I were to throw out the light weight's values and re-kern it from scratch there would dozens of pairs rewritten. I want those changes to factor into the regular's kern values, but those, once interpolated, seem to be static.
I've also fixed some broken glyphs in the regular weight and I don't want that work to be overwritten.
Would I interpolate kern pairs without interpolating my glyphs? What method do you recommend? Am I asking the right question?
Thanks in advance.
