‘Signatures of the Invisible’ was shown in London, Rome, Geneva, Lisbon, Japan and the US – the result of a collaboration between University of the Arts London and CERN in Geneva. Leading artists worked with distinguished scientists to make works in response to theoretical physics in order to redefine the relationship between art and science. We designed the exhibition catalogues, invitations, posters, signs and fundraising materials. The invitation to the Rome exhibition was thermographically printed – a technique involving dropping tiny spheres of plastic (or ‘particles’) onto the ink. The bilingual catalogue is a summarized extension of the original two-part catalogue, designed in a pocket-sized format. It features an alpha numeric system: ‘1-11A’ for artists, ‘1-3S’ for scientists and ‘1-2Q’ for inquisitors.
