Ink cartridge Riso S-8113E original black 1000 ml, pack of 2

Original Riso S-8113E black ink cartridges, supplied as a pack of two 1000 ml tubes, are designed for use in compatible Riso risograph duplicators including EZ, RZ, MZ, SF and SFII series. The SF HD formulation is intended for HD-class risographs and supports high-resolution reproduction up to 600x600 dpi. Each 1000 ml tube yields a large number of monochrome impressions; typical output per tube on A4 ranges from approximately 18,000 to 36,000 prints depending on coverage and master settings. The water-based glycerin emulsion with finely dispersed pigment provides rapid paper penetration, consistent black density and stable performance when used with original Riso consumables.

Advantages

The original Riso S-8113E ink is formulated to match Riso duplicators’ mechanical and chemical requirements, reducing wear on contacting parts and maintaining consistent print quality across long runs. Its SF HD pigment dispersion enables fine line reproduction, clear small text and improved tonal gradation for photographic elements at risograph resolutions. The non-toxic, water-based composition minimizes odor and handling risks while ensuring quick absorption and reliable fixing on paper.

Suitable for

• High-volume monochrome office printing and administrative forms
• Light industrial or in-house production runs requiring consistent black density
• Graphic and art projects using risograph HD capability for fine detail and halftone effects
• Educational or community print environments with frequent duplicating needs

How to use

Install a 1000 ml tube into the designated ink compartment of the Riso duplicator according to the machine’s user instructions. Position the tube so it sits securely in the compartment and engage the feed mechanism as specified by the printer model; no special tools are required. Use the appropriate HD master film and machine settings for 600 dpi reproduction when high-detail output is required. Allow the machine to complete its priming cycle or initial feed to ensure consistent ink distribution before beginning production runs.

Usage recommendations

For best results, use only original Riso consumables including SF HD master film and recommended paper types. Monitor ink levels and perform routine maintenance as advised by the risograph manual to prolong component life and maintain print consistency. Store unopened tubes in a cool, dry place and avoid freezing or prolonged exposure to direct sunlight.
