A Risograph uses a print process that is similar to photocopying but achieves a richer ink output that is more in line with silkscreen printing. Original artwork is scanned into the machine creating a master stencil that is wrapped around an ink drum. Then paper runs flat while the ink is applied from the rotating drum.
How it Works:
Risograph in Action
A great, cost effective option for projects with a broad quantity range (50–2500 units).
Fast (2–5 days), though risograph printers are a bit rare so account for some hunting time.
Uncoated papers with a smooth finish are typically recommended. Printing on a weight that is less than 120 lb. cover will more than likely be suggested by the printer.
Maximum artwork and sheet size is 8.5" X 14"
Risographs print one color, one pass at a time. Colors are limited, each requiring their own individual drum. The final product has a vibrant ink quality similar to that of a silkscreen print.
Once files are delivered to the print shop, not much involvement is needed on behalf of the designer.
Printing is done on a Risograph machine (also known as a RISO Printer or RISO Duplicator). The machine looks very similar to a photocopier or laser printer but without a heating element.
