BASES FOR PRINTING WITH COATING PROVIDING IMPROVED PRINTING QUALITY AND RESOLUTION CAPABILITY AT REDUCED CONSUMPTION OF INK

摘要

FIELD: textiles, paper.;SUBSTANCE: invention relates to the pulp and paper industry and relates to the bases for printing with coating that provides improved printing quality and resolution capability at reduced consumption of ink. The product in the form of a paper substrate has on at least one of the first and second surfaces coating swelling under the influence of water, which thickness is less than 10 mcm. The base coating comprises some amount of pigment of coating, which is sufficient to impart at least one surface of the Parker surface evenness of about 4 and is dispersed in a binder matrix for the pigment of coating swelling under the influence of water, in a weight ratio of the coating pigment to the binder matrix of at least 2:1. The pigment of coating comprises larger porous coating pigment particles and smaller coating pigment particles in a weight ratio of at least 0.2:1. Coating of the base provides the porous surface receptive to ink.;EFFECT: invention provides enhanced printing quality and image resolution capability on paper base with coating on an inkjet printer at a reduced level of use of the ink.;57 cl, 4 dwg, 6 tbl, 3 ex
