Riso F Type A3 Digital Duplicator Premium Black Ink Cartridges

Optimize your high-speed institutional printing workflows and drastically reduce your production overhead with professional-grade Riso F Type Black Ink (A3 Format) (OEM SKU: S-6930E / S-8113E). Engineered specifically for Riso’s advanced SF and SF EII series large-format A3 digital duplicators, this high-performance fluid ink utilizes clean, eco-friendly rice bran oil emulsions to generate thousands of sharp, high-contrast impressions with instant absorption and zero bleeding on porous stocks.

 Riso F Type Black Ink (A3 Format) Key Product Features

• Massive High-Yield Output: Packaged in heavy-duty 1000ml cartridges, engineered to produce between 20,000 to 25,000 high-density prints per box (depending on textual text density and solid fills).

• Eco-Friendly Rice Bran Oil: Utilizes a sustainable, plant-derived oil base that drastically reduces volatile organic compounds (VOCs), eliminating harsh chemical odors in closed print rooms while extending screen mesh lifespans.

• Instant Set Drying: Highly volatile oil-in-water paste configuration speeds up absorption into raw paper fiber, eliminating messy ink transfer, offsetting, or smudging in high-speed exit trays.

• RISO i Quality System Integration: Built with an integrated smart-chip sensor configuration that connects instantly with your machine’s primary digital panel, ensuring real-time volume calculations and auto-adjusted flow rates.

• Viscosity Anti-Clogging Guard: Specially balanced formulation resists fluid separation, thickening, or drying out inside delicate internal drum mesh channels during extended weekend idleness.

Technical Specifications

 Riso F Type Black Ink (A3 Format) Pros and Cons

Pros

• Unmatched Mass-Print Savings: Lowers the overall cost-per-page for institutional print queues to mere fractions of a shilling, easily outperforming heated laser copiers on volume runs.

• Cold-Process Mechanical Lifecycle: Operates entirely via mechanical pressure and absorption without hot fusion elements, protecting internal hardware and lowering office electricity draw.

• Large Format Stability: Formulated to stay perfectly uniform across expansive A3 layout drums without pooling or structural bleeding.

Cons

• Porous Stock Paper Requirement: Completely incompatible with smooth silk, gloss, clay-coated, or specialized digital photo papers where ink cannot settle naturally into the fibers.

• Exclusivity Limits: Formulated strictly for F Type print drum ports; cannot latch into legacy RZ, EZ, or compact CV/CZ series drum housings.

Verdict

For operations relying on the daily runtime of Riso SF and SF EII series large-format systems, utilizing high-grade Riso F Type Emulsion Supplies is critical. Substandard generic formulations often feature unbalanced oil ratios that leak from the print drum, creating blurry prints, heavy background tinting, and premature wear on your machine’s separation rollers. Sticking with verified supply channels keeps your print lines readable and protects your hardware from costly emergency field service calls.
