HP 3M 891 Ink cartridge, 10 L, Optimizer

The HP 3M 891 (G0Y78A) is a 10-liter latex optimizer cartridge developed for industrial-scale HP Latex printing systems used in large-format graphics production. This cartridge serves as a functional component in the printing process, where the optimizer fluid is applied to interact with latex pigments, fixing them rapidly to the media surface. This chemical interaction improves image sharpness and ensures color uniformity across extended high-volume production cycles. Designed for large print service providers and high-capacity fleets, the 10,000 ml volume reduces the necessary frequency of manual supply interventions during long-run print jobs. The product supports high-speed operation while maintaining output quality on a variety of substrates. It meets established environmental standards, holding both UL ECOLOGO and UL GREENGUARD GOLD certifications for low chemical emissions. This single-pack ink cartridge is technically compatible with the HP Latex 3500, 3600, and 3800 Jumbo printer models.
