Description

HP 821 Latex Ink offers Scratch resistance comparible to that of hard solvent inks on vinyl and banner. With the NEW LatexOptimizer you can achieve High Image Quality at High Speed

HP 821 Latex Inks are formulated to optimize and maintain the high performance and print quality of HP 821 Latex Printheads, and they work with HP 821 Latex Optimizer to provide high print quality at high productivity.

HP 821 Latex Inks have a water-based formulation with an innovative “latex” polymer that produces a durable, flexible film protecting the image. Prints are completely dried and cured in the printer and are ready to use. A 6-color system of pigment inks—cyan, magenta, yellow, black, light cyan, and light magenta—produces a wide color gamut.

HP Latex Optimizer

HP Latex Optimizer—OP—is a new component of HP 821 Latex Inks. HP Latex Optimizer consists of positively-charged (cationic) polymers suspended in a colorless, water-based ink vehicle.

OP is applied proportional to local ink coverage by an HP 821 Latex Printhead, and the amount can be adjusted by the user for specific materials. The use of OP has a low impact on the cost of the print. On the print, the positively-charged OP polymers are attracted to and adsorb onto—“coat”— the negatively-charged pigments. The surface charge of pigments is neutralized causing them to aggregate and become immobilized on the print surface. This produces sharp text and image detail by suppressing feathering and color bleed, especially at high productivity levels.

Previous generations of HP Latex Inks use print zone heating to immobilize the pigments on the print. Evaporating water from the ink causes a rapid rise in the viscosity of the liquid ink film, and this keeps pigments in place. HP Latex Optimizer accomplishes this effect chemically—by charge neutralization—so that water does not need to be evaporated so rapidly.

As a result, the print and curing zone dryers in the HP Latex L110 Printer series are more energy efficient and operate at lower temperatures than previous generations of HP Latex Printers.
