An image is either sent digitally from the Riso PC or from a physical original via the scanner bed. The master is created by burning the image onto the master roll inside the printer. This stencil is then wrapped around the ink drum. The Riso feeds paper under the ink drum as it rotates, and ink is pushed out through the stencil to create an impression.
On our Riso, two colors are printed at a time, and multicolored prints are made by switching out drums, then printing over each layer. The paper passes through the machine multiple times.
Risograph ink is translucent, so its final appearance depends on the color of the paper it is printed on and the layering of each ink. Colors can be overprinted to create new ones. It’s also possible to blend any combination of tints of color together to produce color variants.
Ways to participate in CCS Riso
The IC offers Service Printing year-round and formal Riso Training in the Fall. Trained students can rent time in the Riso Room year-round. Fall training space is limited and accepts applications from Sophomores, Juniors, and Seniors. The IC hosts Riso Printing events during the school year and student organizations (e.g. Riso Club, Freeform Press) use the Risograph for club events.
