Rafaël Rozendaal and Jürg Lehni discuss their shared interest in vector graphics, which are based on mathematically-formulated geometrical entities such as lines, curves and points, in contrast to more commonly used bitmap graphics, in which values are assigned to grids of pixels. The text was first published in Spheres Magazine by Swiss graphic designer Philippe Karrer, and later made available for online reading on Rhizome.org.
In 2009 the École Cantonal d’Art de Lausanne (ECAL) published Typeface As Program, a book which originated in the efforts of its graphic design programme to teach type design as a separate discipline. The book summarises a series of workshops on the technical processes of type creation, and includes a comprehensive essay and three interviews by Jürg Lehni on the nature of digital type design and font software. The interviewees are Peter Biľak, Erik Spiekermann and Dimitri Bruni.
The catalogue documents The Most Beautiful Swiss Books 2009, the anual competition aimed at promoting Swiss book design. The Future Issue is the third catalogue designed by Laurenz Brunner as part of the Back To The Future Trilogy, concerned with the past, present and future of book design. Next to presenting the award-winning books, the catalogue also provides a selection of essays on the future of the book, of which one is written by Jürg Lehni.
