FIELD: pulp-and-paper industry. SUBSTANCE: invention relates to production of printer's paper. Water- fibrous dispersion of cellulose fiber is prepared, which is supplemented, glued, and precipitated with coagulant and flocculant, the former being aluminum sulfate and the latter: polysulfone-pyrrolidinium chloride, MW 2500-3000; or copolymer of methacrylamide with methacrylic acid ammonium salt, MW 10000-100000; or piperylene-acrylonitrile copolymer, MW 10000; or piperylene-methacrylic acid copolymer, MW 10000. EFFECT: enhanced efficiency of paper production, increased degree of paper pulp and kaolin retention, improved physico-chemical characteristics of paper, and reduced specific consumption of wood. 2 cl, 1 tbl, 5 ex
