Abstract:
A method of producing the low glare, high print gloss paper of the invention comprises the steps of providing a paper substrate, coating the substrate with an aqueous coating composition having, as a dry parts by weight per 100 parts of pigment, 50-90 parts coarse delaminated clay pigment having a particle size of 8-12 microns and 10-20 parts calcium carbonate having a particle size of between 0.7 and 1.1 microns, drying the coating; and supercalendering the coated substrate with at least two passes per side with rolls having a surface roughness of 90-130 Ra. The step of supercalendering imparts a Parker Print-Surf roughness of 1.7-2.2 microns and a sheet gloss of about 25-30. Four color printing produces a print gloss of 65-70 and a delta gloss of at least 38.
