I was in charge of the experimental page of color layering in a collection of RISOGRAPH printing samples by 14 designers. I used apples and bananas as a motif, expressing the ripening process by layering yellow to red and green to gold. Since the colors of lithographs vary depending on the order of printing, I started from Table 1 and Table 4, and the colors ripened as I moved to the center of the page. I also sewed the pages together with a sewing machine.
