Frequently asked questions

Questions about Riso

What is Riso?

Riso Kagaku Corporation is a Japanese company which is the inventor and distributor of Riso print equipment, specifically the Risograph machines that we print with.

Though it looks on the outside like a copy machine, the Risograph is NOT a copier. It is a duplicator (think mimeograph) with a process like silk screening. 

The Riso was marketed for high volume and inexpensive duplicating. And to this day, it is mainly used by businesses, schools and churches who need production runs of 50 to 10,000 prints of the same thing.

Because of Riso’s similarities to screen printing and the availability of 21 standard colors along with 50 custom colors, designers and artists have begun adapting these machines to produce beautiful and unique works. 

How does it work?

Riso combines the best of digital and traditional print: a hand-made look and feel with the speed, low-cost and efficiency of a modern printer.

The Riso duplicator internally creates a stencil that is laid onto a drum filled with ink. The drum then spins at high speed, forcing the ink through the stencil onto the paper, where it is absorbed creating a unique look and texture.

What is the largest size you can print?

10.5" x 16.5" on 11"x17" paper

Do you provide the paper?

Yes. We work closely with a local paper distributor and can order any brand you would like (as long as it is uncoated). The paper mills we use the most for our projects are French Paper Co., Neenah, and Domtar.

I'm not able to set up my files for print. Can you help me?

Yes. We charge an hourly fee for file handling and will accept native Adobe files as well as scanned in photos, PDFs, and more. Please refer to our file set-up and if you have any questions don't hesitate to email us.

Do you have a minimum print amount?

Yes. Our minimums are 50 for prints, 100 for books.

How do I pay for my printing job?

Once your quote has been finalized and you want to proceed, we will send you an invoice through email which will include a secure link to pay. We accept all major credit cards and PayPal payments.

Is Riso printing archival?

Riso printing holds up very well inside of books where it is unexposed to direct sunlight. For art prints and posters, most inks have a similar light fastness to dye based inkjet printing. If left in direct sunlight the ink will fade or discolor over time. It is best to keep Riso prints out of direct sunlight and frame them with a UV protective glass or plexi.

Will you print my wedding invitations?

We are sorry to say that we are no longer offering wedding print services unless you are already an established client with our studio.
