To understand the role that paper plays in Risograph printing begins with a brief knowledge of ink behaviour. Soy-Based Risograph Ink dries through a combination process of absorption and evaporation, so it is ideal to find paper stocks with qualities that suit this process. Much like soy-based newspaper printing ink, Riso Inks may smudge after the prints have dried (technically, the ink never really sets). This may be of concern for some projects, especially those with heavy ink coverage, or intended for handling.
