iKern is a system designed to make spacing and kerning different: rational, fast and economical. I'm Igino Marini, I live in Italy, and I am an engineer. In the 2000s, I became interested in fonts by digitising the Fell Types. iKern started precisely to automate the letter-fitting of those typefaces. But it soon became a project on its own. Not very different from my previous career in structural analysis and robotics: using maths not just as a tool but as a language. Today iKern is a service for type designers and font companies. It allows to free up resources and to optimise time, without compromising on quality.
