Engineered Pigments for Inkjet Receptive Media
Abstract:Silica, kaolin and calcium carbonate pigments have been engineered for inkjet receptive media. These pigments have been synthesized by a range of companies to create a surface that produces improved quality for inkjet printing paper. Precipitated Calcium Carbonate (PCC) has been available for several years for inkjet coatings but had application limitations with regard to coat weight and coater speeds due to low solids content. To address this limitation, a second generation of PCC for inkjet receptive media has been synthesized with a significant increase in solids content.
The second generation pigments have been evaluated on pilot as well as commercial coaters with great success. Increased pigment solids yield increased coating color solids which, in turn, allow this pigment to run at higher coat weight and higher coater speed on standard coating equipment. The new PCCs can successfully create matte grade papers with improved coater productivity relative to the traditional synthetic silica coatings.
This paper will compare PCC hand coated drawdowns and commercially available inkjet sheets coated with silica, kaolin and/or calcium carbonate through a series of inkjet print evaluations and image analysis. The commercially coated sheets were characterized by XPS surface analysis to determine pigment and binder content.

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.
