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.

What is claimed is: 1. A low glare, high print gloss coated paper comprising: a substrate; a coating on said substrate, said coating comprising plural pigments, 50-90 parts per 100 parts dry weigh of said pigments comprising coarse delaminated clay, and between 5 and 12 parts starch and between 5 and 12 parts latex per 100 parts dry weigh of said pigments; and a surface of said coating having a Parker Print-Surf roughness no greater than about 2.2 microns, a sheet gloss level no greater than about 30, and an ink tack rate in the range of about 0.02 N/Sec. to about 0.04 N/Sec. 2. A low glare, high print gloss coated paper as in claim 1, wherein said surface coating when 4-color printed has a delta gloss of at least about 38. 3. A low glare, high print gloss coated paper as in claim 1, wherein said surface coating when 4-color printed has a print gloss of at least about 65. 4. A low glare, high print gloss coated paper as in claim 1, wherein said coating comprises 10-20 parts coarse calcium carbonate. 5. A low glare, high print gloss coated paper, comprising a cellulous substrate; a coating on said substrate comprising, as a dry parts by weight per 100 parts of pigments, 50-90 parts delaminated clay having an average particle size of 8-12 microns, 10-20 parts calcium carbonate having an average particle size of 0.7-1.1 microns, 7-10 parts starch, and 7-10 parts latex; the surface of said coating being supercalendered with rough surfaced rolls to have a sheet gloss level of 25-30; and said paper having when printed a 4-color delta gloss of at least 38. 6. A low glare, high print gloss coated paper as in claim 5, said paper having a Parker Print-Surf roughness of 1.7-2.2 microns. 7. A low glare, high print gloss coated paper, comprising a cellulous substrate; a coating on said substrate comprising, as a dry parts by weight per 100 parts of pigments, 50-90 parts coarse delaminated clay, 10-20 parts coarse calcium carbonate, 6-12 parts starch, and 6-12 parts latex; the surface of said coating being mechanically treated to have a Parker Print-Surf roughness of 1.7-2.2 microns and a sheet gloss level less than 30; and said paper having when printed a 4-color print gloss of at least about 65.
