1 Risograph @ Lab

Risograph @ Lab

Risograph is a brand of digital duplicators manufactured by the Riso Kagaku Corporation, that are designed mainly for high-volume photocopying and printing. It was released in Japan in 1980. The RISOGRAPH is a stencil printing style digital duplicator. It works by piercing a printing stencil plate with holes and passing ink through the holes to transfer an image onto paper. Due to working with vegetable based ink and organic based master, large-volume printing with less power consumption than e.g. off set, printing with the risograph is environmentally considerate.

Materials and ink

paper: from 60 gr. to max. 300 gr. The paper should be uncoated, eg Munken Print. (We have paper available for first testing.)
ink: vegetable based mark (rice bran oil ink for black, vegetable oil ink for colours)
master: rice based paper
available colours at our lab: two shades of blue, yellow, dark green, fluorescent/ neon pink, flat gold, black:

Getting started

The following is to explain the process. First there will be an introduction and discussion of your project in advance to clear up questions and what processes are the most suitable for your idea.

Preparing images

some basics: basic print setup

Printing

switch the printer on
open the tray and the feeder
type passcode: 1914
start with "MasterMake"
feed paper: it's always better to set an excess amount of paper - if there is only a few sheets remaining, often paper jam happens
set ink cartridge (there are pink, blue, medium blue, green, yellow, gold and black)
turn on the PC
transfer data using Wolke (private window recommended) or USB stick
lazy way
1. print from the browser
2. set to no frame, and adjust the magnification to fit the paper
3. print
proper way
1. open the paper in acrobat etc
2. press print settings (Einstellungen)
3. ...
on the printer, press Pause
press Output. It will start making a "master", and print 2 sheets
use the keypad to set the quantity and print

Cleaning

...
generally after your printing process: with a soft tissue/ cloth and some water, clean residue at the machine
during the process: if necessary, the roll at the paper feeder must be cleaned carefully with a damp cloth to avoid ink abrasion on subsequent paper
