ComColor GN targets high-volume print workflows
The new lineup combines stationary, in-line printheads with RISO’s proprietary oil-based pigment ink. Beyond printing speed, the company says it has optimized startup, cleaning and recovery from sleep mode, with optional high-speed scanning intended to shorten the overall workflow.
RISO’s ComColor GN product specifications list two models and note that continuous printing speed varies with the optional output equipment connected. The flagship’s maximum rating is therefore a specified operating benchmark, not a guaranteed speed for every print job.
The launch announcement qualifies the 180-page-per-minute figure as continuous, single-sided A4 printing with long-edge feeding, standard density and the Face Down Tray.
| Item | Details |
|---|---|
| GN7630 rated speed | 160 pages per minute |
| Listed paper size | A3/Ledger for both models |
| Paper feeding | Multiple paper trays and a standard tray for both models |
| Recycled plastic resin | 15% in the main unit, three times the share in previous models |
Heatless printing supports finishing and media handling
RISO says its heatless process avoids the heat and pressure used by laser printers, helping prevent paper curling. Keeping sheets flat is intended to support stable double-sided printing and subsequent sorting, stapling and booklet binding.
Newly formulated ink and updated printheads are designed to increase color density and expand the color range. The company also cites improved paper transport and ink placement for fine text, barcodes and images on media including envelopes and postcards.
For organizations producing invoices or mailings, the practical offering extends beyond raw printing speed: modular finishing options can connect printing with document preparation.
Energy claims and regional availability
RISO says the heatless process lowers weekly energy consumption, measured through the TEC metric. The announcement does not quantify that reduction, so it does not establish a specific electricity-cost saving.
The printers also allow users to view estimated carbon dioxide reductions on the color touchscreen. These are estimates displayed by the equipment, rather than independently verified savings for a particular customer.
RISO advises buyers to check with local sales offices or distributors for detailed specifications and availability. The global announcement does not establish a single worldwide on-sale date.
Conclusion
The launch adds faster printing and updated media handling to RISO’s high-volume lineup. For prospective buyers, the next practical checkpoint is confirmation of local availability, specifications and finishing options.
