Abstract

With the advent of inkjet printing capabilities, paper manufacturers had to begin new research into new types of coatings that would enhance the print quality of these printers. Printing of this nature was important to the industry since small businesses and people working at home could easily print documents and images of great quality at a relatively low cost. New coatings that began to be looked at by the industry involved the use of more specialty pigments such as silica's and calcium carbonates. These pigments are necessary for paper that will be printed through the inkjet printer medial because no drying stage for printing occurs afterwards. This means that water from the ink must be absorbed quickly by the coating to prevent smearing of the ink and to prevent wetting of the substrate. Research into these coatings also focused on the improvement of optical properties as well based on pigment packing structure. This paper is an extension of a study performed by Hyun-Kook Lee at Western Michigan University, which focuses on how well the coatings compare in packing structure when the papers are printed on an inkjet printer. Properties that were quantified include brightness, gloss, porosity, ink density, dot area, dot roundness, color gamut, and LAB values. A final analysis showed which coating not only gave off excellent optical properties, but also provided a superior print quality.
