Short story about Risograph
Risograph or RISO is a digital duplicator manufactured, invented, and distributed by the RISO Kagaku Corporation brand, whose history dates back to 1946, when its founder Noboru Hayama began manufacturing and selling duplicators that enabled high-volume print duplication at low cost in Tokyo. Because printing inks were imported in small quantities at the time, acquiring printing consumables was extremely expensive and time-consuming, Noboru's invention - the first Japanese emulsion ink - was a watershed moment for him.
RISO Kagaku Corporation runs three research and development facilities in Japan right now. Speed, durability, adaptability, cost-effectiveness, and ecological friendliness are just some of the ways in which its printing technologies have long outpaced many of its competitors.

Risograph combines the benefits of screen, offset, and digital printing.
The risograph's printing cylinder automatically mounts the matrix, which was generated thermally, and wets it with ink from the cartridge within. The sheets are drawn in at speeds of up to 150 pages per minute, and the picture from the matrix is positively printed on them in a rotating process (depending on the model of RISO in one or two colors during one printing run).Order print
The RISO printing process is the most eco-friendly option.
The production wastes of RISO ink made from rice bran and vegetable oil are utilized as animal feed, and the ink itself can come into touch with food because of its lower VOC content. All disposable items, such as ink cartridges and biodegradable matrices produced from banana fibers, are not only of the greatest quality but can also be recycled. Low-temperature, no-fuse cold printing is not only faster, but it also uses less power, produces no ozone, and is compatible with recycled paper.
The risograph has its own special colour pallet. Paperiso has 7 colours ranging from rich deep tones to vibrant fluorescents. There are not only these pure spot colours to use but also the soy-based ink that allows colours to be overlayed in order to create new ones. This means you can create a three colour print with only two colours for example- you can even print CMYK photos!

There are range of different effects and colours that can be obtained by overlaying individual colours and varying the paper stock!See more
Papers with certification
RISO ink is designed for use on uncoated paper and is compatible with a wide range of paper stocks weighing 80 to 270 g/m2 (and up to 300 g/m2 with proof printing), including recyclable and recycled papers. In addition to the papers shown on swatches, we have a large selection of papers available for purchase. Another option is to send us your own prepared paper.See more

Configuration of files
How should a file be prepared?
Make sure that when you send in a graphic or design to be printed, the files follow these rules.
Flattened PDF (no layers or transparencies)
Set to Greyscale / B&W
Resolution = 300dpi + Size = A3
Each colour layer saved as a separate fileDownload Templates
Pick a color
We provide a total of 8 color options to pick from when designing your RISO print. Changing the layer's blending mode to Multiply / Multiply will show you how the colors blend together. Keep in mind that the color values do not account for any special effects like metallic texture or fluorescence.
Separate the colors into distinct layers
In RISO, each color is printed using its own cylinder. It's imperative that you remember to export each color as its own PDF file, labeled with its respective color name, while preparing a file for printing.
Set to greyscale
Don't forget to transform the layers to a grayscale image before saving them as individual files. Full-tone black regions in an image will be reproduced at 100% in the color of your choosing, while lighter areas will be left more transparent. The swatch book we provide will help you much when creating a print layout.
