Abrasion Resistance of Aqueous Pigmented Inkjet Inks on Coated Paper
Abstract:High-speed water-based inkjet printing has recently made inroads into traditional commercial printing because of its reasonable cost and environmental friendliness. In the commercial printing fields dealing with magazines, fliers, and brochures, low penetrative gloss coated paper is generally used. When inkjet droplets are impacted on that type of paper, their liquid components evaporate and penetrate into the paper very slowly, while solid components, such as pigment and polymer, are filtered and form an ink layer on the paper. Since impacted droplets dry slowly and the formed ink layer is directly exposed to external forces, abrasion resistance of inks on coated paper is a serious problem in comparison with that on porous plain paper. In this study, the mechanism of abrasion resistance of pigmented inkjet inks on coated paper was investigated in terms of surface friction, strength of ink layer and adhesion to substrate. The result indicated that the strength of ink layer was the major factor, and we could impressively improve abrasion resistance performance by controlling that factor from a rheological view point

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
