Print just what you envision, then print it again with the same vivid color and same quality. Pigment inks are formulated through rigorous testing — up to 1000 prototype formulations subjected to hundreds of tests for ink-cartridge-printer-media interaction, with over 20 purity tests to prevent clogging contaminants. Ultra-pure pigments remain evenly dispersed, preventing settling and clumping that can clog printhead nozzles. Prints resist fading for over 200 years on a range of HP media. The HP DesignJet printing system — printer, cartridges, printheads, media — is engineered to work with precision, saving time and lowering printing costs. Compatible with HP DesignJet Z2100, Z3100, Z3200, Z5200, and Z5400 printers.
