Protocol No. 9Protocol magazine is published annually by architecture students of the Berlin University of the Arts. The 9th issue focuses on the topic of “Fehler”(german for error/mistake). To embody a sense of impromptu and lack of control, the entire magazine was printed in the “iris” technique. Three spot colours were mixed on press to achieve natural gradients for all images and text. With each printing sheet the gradients become more diffused, making every copy of the magazine unique. Additionally, a custom typeface adaptation, Primago, was developed specifically for this issue. The project was created together with Nora Hollstein.
