摘要:
The ink set of this invention comprises at least two inks, one of which contains a pH sensitive polymer and pigment colorant with dispersant. A second ink is provided which comprises incompatible inorganic or organic salts or has an appropriate pH. The polymer precipitates onto a medium upon contact with the second ink, thereby providing improved bleed control.

An inkjet cleaning unit includes a reservoir housing an inkjet wiping fluid that includes a non-wettable material; and an applicator wick fluidly coupled to the reservoir, in which the applicator wick is configured to transport the inkjet wiping fluid from the reservoir to a surface of an inkjet material dispenser. A method for cleaning an inkjet material dispenser includes applying an inkjet wiping fluid from a reservoir housing the inkjet wiping fluid to a surface of the inkjet material dispenser; in which the inkjet wiping fluid includes a non-wettable material; and in which an applicator wick is fluidly coupled to the reservoir to transport the inkjet wiping fluid from the reservoir to the surface of the inkjet material dispenser.

The ink set of this invention comprises at least two inks, one of which contains a pH sensitive polymer and preferably a self-dispersing pigment colorant. A second ink is provided which comprises incompatible inorganic or organic salts or has an appropriate pH. The polymer precipitates onto a medium upon contact with the second ink, thereby providing improved bleed and halo control.

A fluid dispensing system for ink-jet printing can comprise an ink-jet ink including anionic dye colorant and from 0.05 wt % to 1.0 wt % of an anionic dispersant polymer, and a fixer composition including a cationic crashing agent that is with a component of the ink-jet ink. The fixer composition can be stored separately from the ink-jet ink, and the fluid dispensing system can be configured for overprinting or underprinting the fixer composition with respect to the ink-jet ink.

摘要:
Bleed control and fast dry times are achieved in aqueous pigment dispersion-based ink-jet ink compositions by formulating the ink compositions to comprise at least one aqueous pigment dispersion and a microemulsion comprising at least one water-insoluble organic compound, at least one hydrotropic amphiphile, and water. The hydrotropic amphiphile is present in the microemulsion in an amount sufficient to solubilize the water-insoluble organic compound.
摘要:
The present invention is drawn to methods and architecture for depositing one or more self-assembled monolayer(s) onto a print nozzle orifice plate surface. In particular, the servicing fluid includes a self-assembled monolayer-forming agent and is applied using a wiper. The wiper is configured to service and maintain an orifice plate surface having a pre-existing self-assembled monolayer, or for initial application of a self-assembled monolayer to an orifice plate.
