Abstract
An inkjet fixer composition and a printing method and system used with the composition are disclosed herein. The composition includes: a) from 1 to 8 weight percent cationic polymer; and b) from 0 to 2 weight percent of at least one surfactant selected from the group consisting of nonionic surfactant, cationic surfactant and combinations thereof; and c) an aqueous liquid vehicle. Upon overprinting the fixer composition with an ink-jet ink on a substrate, the fixer composition vehicle and the ink-jet ink vehicle form a vehicle mixture on the substrate after which the vehicle mixture penetrates into the substrate, and an ink image is formed on the substrate.
