Image size

The RISOGRAPH will print a maximum image size of 10.25 X 16.25 on 11X17 paper. This provides us room for cutting guide marks and bleed considerations and is good to keep in mind while designing your prints.


Paper type

RISO is best suited for paper weights from 20lb bond to 80lb cover stock. Because the ink is soy oil based, we can only print on uncoated paper. Paper with high absorbency yields the best results. You are welcome to provide your own paper if it meets these specifications, but we are happy to use our stock or special order paper for your project. 


File preparation

When preparing your images, it is helpful to think of the RISO as a screen printing machine. You will need to provide JPEG grayscale images if printing with digital files, and each layer must be its own separate file or channel. Images should be 300-600 dpi. Although we do charge an hourly fee for image formatting and preparation, we are happy to answer questions via email .

Large, dark areas will cause jams and roller marks. It is wise to keep them at 75% opacity or less for the best result. Reserve 100% opacity for important details and text.

If possible, provide a full color JPEG for reference. 

While using the network to print gives us great control of the result, we encourage experimentation!

Feel free to collage or draw your print and then use the scan bed to get a less predictable, more experimental result. We are happy to work with you to test your RISO ideas, but keep in mind we do charge hourly for design and formatting.


Considerations  & disclaimers

  • Images with more than one layer will have imperfect registration. That is, we can accomplish duotone and multicolor images that look great, but they may not be perfectly lined up. The quickness of the printing process means that paper shifts quite a bit during a run. This increases with the number of prints produced at once, but do not despair! Most misregistration looks super neat and you can tell all your friends it was on purpose. 
  • Roller marks may appear when images have heavily inked areas or when printing double-sided images. We try to mitigate these effects by printing the most heavily inked parts of an image last, however, there is still opportunity for smudging.  These marks may be lightened or removed with a soft rubber eraser.

  • Needle marks, uneven areas and ink transfer are all possible and LIKELY, although we do all we can to keep your images as crisp and neat as possible. Part of the beauty and uniqueness of a RISO print is in its unpredictability! Each print is different from the last and that's OK.
