Announcement

RISO KAGAKU CORPORATION announced the launch of its ComColor GN Series of ultra‑high‑speed full‑color inkjet printers, with the flagship GN9830 model delivering a simplex print speed of 180 pages per minute.

Technical Highlights

The GN series employs RISO’s proprietary heatless, oil‑based pigment ink technology. Stationary in‑line printheads provide continuous feeding, while optimized startup, cleaning and sleep‑recovery cycles, together with an optional high‑speed scanning module, accelerate print workflows. The heatless process eliminates the thermal curing step used in laser printers, preventing paper curl and ensuring flat sheets for stable duplex printing and downstream operations such as automatic sorting, stapling and booklet binding.

Print Quality and Media Handling

Newly formulated inks expand the colour gamut and density, delivering vibrant reproduction with sharper images, crisp bar‑codes and fine text. Improved transport stability and precise ink placement support a range of media, including envelopes and postcards, and enable high‑quality output for transactional documents, manuals and enveloped mailings.

Sustainability and Energy Efficiency

The heat‑less mechanism reduces weekly energy consumption, measured by a lower TEC value. The main unit incorporates 15 % recycled‑plastic resin—a three‑fold increase over previous models—thereby lowering lifecycle carbon emissions. The printer’s colour touch screen allows users to view estimated CO₂ reductions for each job.

Market Position and Availability

RISO positions the GN series for high‑volume printing environments such as invoice processing, manual production and bulk mail. The GN9830 specifications are based on office colour printers commercially available as of April 2026 (Data Supply Inc.). Product names, specifications and launch dates may differ by region; interested parties should contact local RISO sales offices or distributors for detailed information.

Corporate Background

Founded in Tokyo on 2 September 1946 as a mimeograph business, RISO KAGAKU has evolved into a global printing‑equipment manufacturer serving more than 190 countries. The company celebrated its 80th anniversary in September 2026.
