We work on a GR3770 printer that can print up to an 11x17” format. In order to be ready for riso printing, digital files have to be prepared a certain way.

If you are submitting a completely designed and prepped file, you will only be charged for the prints. However, if your files are not prepped for riso printing or you want us to do this work for you, you will be charged an additional prep/design fee of $50/hr. If you need help designing or laying out your work, we can assist for $75/hr.  Our typical turnaround time is 2 weeks. 


Risograph involves a process similar to that of screen printing.  The original image is scanned on the machine and burned onto a master copy, which is then wrapped around a print drum.  Rotating at high speed, the drum pushes the ink through the screen and onto the paper as it  passes through the machine.

Just as with screen printing, your artwork should be setup as separate greyscale PDF files, one for each color layer.  Please note that the Riso cannot print full bleed, and large areas of block color won't print out evenly, and will also cause print marks.  There is a 1/4 inch border on prints.

We currently stock these colors: black, burgundy, blue, green, medium blue, bright red, teal, hunter green, brown, yellow, fluorescent pink. These colors can be blended to make new colors by layering and altering opacity. More about colors here.


To prepare your artwork for printing, first you need to save each color layer as a separate grayscale file (PDF). Keep art as vectors (outlined) when exporting. All solid shapes, type and images should be set to Registration Black (from 5% to 100% opacity).

If your project is full-bleed, include at least an 1/8 inch bleed area.

Please send us your work in Illustrator (Folder), PSD, Indesign (Folder), PDF or JPEG (High-res - 300-600 DPI). Images in PDF must be JPEG, grayscale and 300dpi; no effects and no transparency.

Fonts cannot be smaller than 5pt. and lines 1 pt minimum.

Due to the quirks of Riso, avoid large areas of solid color (they should be at max 50% opacity). Be sure to send us a full color JPEG or PDF as a reference.


The Riso can print on paper sizes up to 11" x 17" and weights from 20lb bond to 110lb card stock.

Riso inks work on most uncoated papers, and do not work on any coated papers or tracing papers. If you are looking for a specialty paper stock, we recommend checking out French Paper Co. We are also happy to suggest paper for you.



Riso ink is made of soy oil, water and pigment, so like newspaper ink, smudging is a possibility.  Also, as Riso ink can smudge or rub off, it is preferable to avoid large block areas of color for flyers and covers, in particular bright colors. We can advise on how to make a project more smudge proof.

Needle Marks

The print is picked off the print drum when printing with a needle, and heavy ink blocking will make the needle drag across the paper leaving a line.

Ink Transfer

Heavy ink can lead to transfer between prints as the prints are stacked on top of each other as they exit the printer.

Roller Marks

Paper feeder rollers may leave marks on the page when a paper is run through the Riso multiple times and has heavy ink. This can be avoided by printing heavy inks last, and let them dry overnight.


Just as with screen printing, with Riso each ink color is layered on separately. That means a single sheet of paper will run through the machine multiple times for projects printing more than 2 layers, and the registration of color can be irregular.  Print marks may also appear, but these can be easily rubbed off with an eraser.

Uneven coverage

If printing large blocks for solid ink, coverage might vary slightly, and there may be differences in gradation.
