Abstract: In this study, we studied the effects of calcium carbonate, silica, talc and sericite on the image quality of coated inkjet paper. These papers are used as dye sublimation transfer paper for printing on fabrics. Evaluate the brightness, smoothness and contact angle of coated paper. Then the paper is printed with the textile color image evaluation test table, and the printed image is evaluated according to six criteria: solid ink density, tone value increase, print contrast, ink trap, gray scale and tone error. The overall printing image quality is related to the smoothness and brightness of the coated paper, but independent of the contact angle. For single pigment coated paper, the paper produced by CaCO3 has the best color difference performance and can be used as a substituteituted for silica. On the other hand, SiO2 was found to be suitable for blending with talc, calcium carbonate, and sericite, and its combination with these materials generally produced better image qualities than silica alone. Talc and sericite, when blended with silica as composite coating pigments, produced better printed image qualities than those as single-pigment-coated papers. The overall image quality ranking suggests that the best performance was achieved with CaCO3-, SiO2 talc-, CaCO3 SiO2-, SiO2 sericite-, and SiO2-coated papers.
