The magic of FORCEJET technology

FORCEJETâ„¢ technology is found exclusively in the RISO’s inkjet product line. RISO built its inkjet technology on the proven track record of the duplicator chassis, but instead of individual ink cylinders printing static information, RISO used heavy-duty inkjet print heads capable of creating full-color variable images.


How it works

RISO ComColor high-speed inkjet printers employ 24 in-line Piezo drop-on-demand print heads. Each of the four colors (cyan, magenta, yellow, and black) has six print heads in a row imaging the page.

Piezo print heads use vibration to create ink droplets. The print heads are stationary and the paper passes underneath them. As the paper moves beneath the print heads the print heads lay down the individual colors that make up the four-color print: cyan, black, magenta, yellow. The fixed position of the print head makes possible the high printing speeds found in ComColor inkjet printers, and it also results in a longer life span for the equipment.


Why our ComColor high-speed inkjet printers are faster, cheaper, and more reliable than conventional inkjet and toner-based technology

Thermal inkjet print heads are found in almost all desktop inkjet printers and many in-line mail addressing systems. Unlike Piezo systems, thermal inkjet printers use an electrical charge to heat the ink inside the print cartridge to form ink droplets. The print head shuttles back and forth across the page as it applies ink to paper. As a result, this technology is much slower and far less reliable, and its cost-per-page is substantially higher than RISO’s FORCEJET technology. Thermal inkjet printers also have a much shorter expected life span. Commercial-grade inkjet printers using shuttle head technology are available that offer higher print speeds, but they are still much slower than ComColor.

Serial or dot matrix printers are commonly found in data processing centers, medical offices, shipping and receiving docks, and other locations where continuous and multi-part forms are used. Since these printers are impact-based (meaning an ink ribbon is struck against the paper) they are well-suited to printing multi-part carbon copies.


Digital Duplicator Supplies

Unique Ink Formulations

RISO 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.


More Copies in Every Tube of Ink

RISO inks are designed to work with our unique vacuum-drawn ink delivery system, that ensures that every drop of ink is consumed.


Consistent Results

Our 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.


Precision Engineered Masters

RISO masters are developed specifically for the RISO printing process and manufactured to rigorous engineering specifications allowing the thermal print head to precisely replicate the digitally scanned image onto the master.


Protecting Your Investment

Our advanced formulations can also extend the life of the machine. Ink that separates not only results in poor image quality, but the water from this separation can cause corrosion in the cylinder. RISO masters are formulated to work perfectly with the master loading and disposal systems, as well as the thermal head that produces the image. RISO supplies ensure great, clear copy, and no worry about the possibility of damage to machine parts that can result from using non-RISO inks and masters.
