What are the main difference between a photocopier and a risograph?
Risographs are based on a stencil-and-ink system, while photocopiers use electrostatically charged toner particles, like a laser printer. Each type of machine does best with a specific job type and volume.
How does Riso printing work?
The Riso internally creates a stencil that is laid onto a drum filled with ink which then spins at high speed, forcing the ink through the stencil onto the paper. This process creates a unique textured print that cannot be replicated. Unlike digital printing, there’s no option to print in standard ink colors like CMYK.
How much does a risograph printer cost?
RISO machines range in price $2000-$4000 new.
What is the use of a risograph?
Risograph is a brand of digital duplicators manufactured by the Riso Kagaku Corporation, that are designed mainly for high-volume photocopying and printing.
What is a Risograph used for?
What paper is used for Risograph?
Because soy-based ink is liquidy, Risograph printing works best on uncoated paper. The thinnest paper is 20lb bond and the heaviest is 80lb cover (though we are always up for experimenting!) Our favorite papers to work with have either a smooth or vellum finish to it.
How do you prepare a Risograph?
Your files should be separated into individual black & white images for each color that is to be printed. This is similar to preparing files for screen printing. 100% black in each color layer, will print out as 100% of whichever color you are printing.
What is the purpose of risograph?
Are risograph prints archival?
SMUDGING & OFFSET Risograph ink is soy-based and non-archival. This type of ink stays “open” many days after printing and will smudge if enough pressure is applied to it.
Can Riso print photos?
Riso ink is a rice oil-based ink that doesn’t get fully dry, which allows for overprinting, or printing different colors on top of each other. To prevent smudging, use a spray fixative. Convert images to CMYK. The risograph can print full-color images and photographs using the colors cyan, magenta, yellow, and black.
What’s the difference between a Risograph and a printer?
The Risograph, on the other hand, operates more like a printing press, and is often referred to as a printer-duplicator because of its dual function as a network printer as well as a standalone duplicator. Which works best in your office depends on what you copy and how many copies you make.
How does a risograph or RISO duplicator work?
What is a RISOGRAPH or RISO Duplicator. The machine then receives the data and creates a master, or stencil, which is automatically wrapped around an ink drum. When the drum rotates the ink is pressed through the master and transferred onto paper as the sheets are feed through the machine at very high speed.
How does a stencil work on a risograph?
The machine makes a ‘master’ stencil of your design and wraps it around the ink drum. The ink is pushed through the stencil onto the paper as the drum rotates. If you want to incorporate multiple colours, you must change the ink drum, make a new master and place the paper through once more.
How is a risograph used to print zines?
When printing colorful zines, posters or comics with a Risograph, you build your print layer by layer. The machine makes a ‘master’ stencil of your design and wraps it around the ink drum. The ink is pushed through the stencil onto the paper as the drum rotates.
