HP recently unveiled its HP 781 and 791inks for the HP Designjet 8000, 9000 and 10000 printer series. The company says the inks, which it designed specifically for these low-solvent printers, provide the reliable performance, ease of use, and vivid, durable prints that customers rely on when producing high-impact signage. Users can change to the new HP 781 and HP 791 ink cartridges as each color of the HP 780 or HP 790 ink cartridges is ready to be replaced. Prints produced with the new HP 781 and 791 formulations achieve up to three years of display permanence without lamination. They’re engineered to be scratch-, smear-, and crack-resistant.
