Unique Ink Formulations\nRISO ink is tested repeatedly during the formulation process, to insure optimum print quality, as well as consistent performance under a variety of conditions. RISO ink is precisely formulated to work with the master material and the ink delivery system of the Printer-Duplicator to create a clean, sharp image.\n\nMore Copies in Every Tube of Ink\nRISO inks are designed to work with our unique vacuum-drawn ink delivery system, that ensures that every drop of ink is consumed.\n\nConsistent Results\nOur emulsion inks consistently deliver high-quality printing, and when stored properly, can remain in the box or cylinder for long periods of time without the separation or change in viscosity that can result in poor quality and wasted ink and prints.
