Print Gocco PG-10 super This is a simple home printing machine manufactured and sold by Riso Kagaku Corporation from 1977 to 2008. Print Gocco used a printing technology called "stencil printing," which transfers ink through tiny holes made in the master sheet. It was characterized by combining plate making and printing into a single machine. First, a manuscript created by drawing letters and illustrations was placed in the machine and burned onto the master sheet using a flash lamp. Then, ink was applied to the master sheet, which was set in the machine, and printed one sheet at a time onto postcards, etc. Everything in the photo is included. It is not new.
