Ink-jet printing system with reduced nozzle clogging

摘要

A fluid dispensing system for ink-jet printing can comprise an ink-jet ink including anionic dye colorant and from 0.05 wt% to 0.5 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.
