The Risograph is is located in the Rad Lab for your use. Riso Fellows (chosen each term), will print your jobs, which you can pay for with PSU print credits (the same you use for the other Rad Lab printers).

What’s a Risograph?
The Risograph printer, is based on the stencil method of printing, much like screen printing. While the machine looks very much like a photocopier, it functions quite differently. Black & white artwork is sent to the Riso either from the connected desktop pc, or on the scanned on top of the machine. The image is ‘burnt’ on to a paper-like master, which can then be used to duplicate it up to thousands of times. The master wraps automatically around an ink drum. The ink is pushed through the screen/master, and then prints onto paper that makes contact with the drum.

Why would I use one?
There are various reasons, but perhaps the biggest one is that the Risograph allows you to print with ink colors that digital printers simply cannot achieve—rich blues, fluorescents and more.

The Risograph also allows you to explore printing in a more basic sense, as it requires you to print each color individually. This allows for exciting overprinting possibilities as well as unexpected ‘happy accidents’.

How do I prepare my file(s)?
Please read this RisoGuide for a quick start on preparing to print. For a more in depth look, review this Risograph_Intro_Presentation prepared about the Risograph. This handy app, Spectrolite, helps you separate colors (great if you are printing a photograph in more than one color) and do other things like preview your job.

How do I actually print?
At PSU, there are Riso Fellows who print your job for you. Riso printing is moderately labor-intensive, so you’ll need to a lot some time when you come in to print. You will bring in your original art, a paper print, or a digital PDF file (we can’t promise the computer method will always be operational). The Fellow can help you if your file/art isn’t set up correctly or if you have questions. If you are interested in becoming a Fellow, see below.

The Risograph machine was never designed to do highly precise work. It’s important that as you embark on printing your work, that you don’t expect the same kind of results you might get on a laser or inkjet. In fact, that’s what makes the Riso so much fun! It’s a lot of experimentation, and new kinds of outcomes that can be very exciting to work with.

So what can you expect? Registration may not line up perfectly when printing 2 or more colors. The ink rubs off easily, so do expect some smudges (sometimes removable with an eraser). Finally, because you’re printing with single colors, it’s hard to know exactly what the outcome will be, but you can make small adjustments as you print. The Riso Fellow can help you assess your artwork, and then help you should you need to make adjustments.

What is a Riso Fellow, and how do I become one?
The Riso Room Fellowship is a position held by 3 students per term. These students become the masters/mistresses of the machine, learning the ins and outs of it, getting the chance to experiment with it for their own work, as well as printing work for customers during open hours. For more information, contact: Briar Levit, blevit@pdx.edu.
