TREATING MATERIAL FOR SUBSTRATE PROPERTY ENHANCEMENT AND PRINT QUALITY IMPROVEMENT

摘要

A substrate coating is provided for application in association with ink jet ink imaging on the substrate. The coating material, for application on a printable substrate for use with an ink jet printing system, includes a substrate property enhancing component, a surfactant, and deionized water. When the coating material is applied to the printable substrate, prints are produced which have improved print quality. The coating can result in enhanced permanence of black and specialty non-black color ink jet prints, when the substrate enhancing component is a polymer. The coating material of the present invention can also be applied to the porous substrate as a pre-print coating to reduce paper cockle and curl, when the substrate enhancing component is a polyhydroxy compound.
