This is the new Cyan, PIGMENT based color ink cartridge for use with the LX900 Color Label Printer. When paired with Primera''s Tuffcoat Extreme Polyjet material this ink will provide stability against harsh conditions including water, chemicals, abrasion and exposure to long periods of UV light. You must use a pigment-only print head with your LX900 pigment ink. Mixing pigment ink and dye ink will cause poor print quality, reduced water and scratch resistance and damage to the print head or printer. Pigment Print Head = Part # 53472. For best water resistance print on Primera''s Tuffcoat Extreme Polyjet label stock. For best water resistance on any label stock, Primera recommends printing with the color cartridges only. Black areas will still look black. The printer will mix the CMY ink to create black (Process Black). To print with the color cartridges only, set the "Ink Cartridge" setting in the driver to "Color".
