Font and its technologies is a book I've written to help Polish designers in their everyday work. It looks at more technical aspects of fonts, rendering and file formats. Those are the things that influence our everyday design and file output and are not widely spoken about. In the book you can read about interpolation, WOFFs, Variable fonts, OTFs and many other terms. Book is scheduled to be published by Academy of fine arts in Gdańsk with financing from Polish ministry of culture.
