Manifesto

This is a message to type designers. Spacing and kerning is often a tedious job and can sometimes take up to 60% of the font development process. It can be frustrating because it requires your time (and time is never enough) and your energy: the most precious resources blocked on a repetitive task when new designs, that could become new fonts, are waiting and new projects have to be conceived.

iKern is the result of years of research on autospacing and autokerning and it can produce high quality spacing and kerning in short time. It’s proposed to you as an help to optimize your workflow moving your resources towards the “creative” side.

Found iKern referenced on Slanted and felt it was too interesting to pass up a mention on IJC. It’s not a service I have tried or really have any need for, but I know there are plenty of people out there who may want to take a look at it.
