A few years ago TPN produced a cover for Novum that caused a real stir with its thermosensitive surface – an image of a sunbather turned red when the cover was exposed to UV light (novum 08.13). For the art work for this November’s cover (novum 11.18), the team from Hamburg and Barcelona created a graphic solution to really do justice to and highlight the special hot foil technique and it’s 3D effect. TPN: »›Form is the body of colour – colour is the soul of form‹ – so wrote graphic designer and artist Karl Gerstner, who died last year. We owe a great debt of thanks to Gerstner. His approach to design problems has had a strong influence on us. For this cover of novum we captured the soul of autumn in a flexible visual system. The form system comes from investigations carried out for a book about the design of flexible visual systems that we are currently working on.«
