FIELD: printing industry. n SUBSTANCE: invention relates to colorful composition for high-speed screen printing on variety of materials. Composition includes solvent with boiling point of at least 170 °C in amount of at least 70 % by weight of solvent total weight, prepolymer selected from one or more urethane acrylates, polyester acrylates, epoxy acrylates, or polymeric resin, preferably acrylic, polyester, epoxy, vinyl chloride-vinyl acetate copolymer or combination thereof in amount of from 7 to 70 % of total weight of composition. Composition has viscosity of from 6 to 30 Pa⋅s at 25 °C, thixotropy index (TI) of 2.0 to 8.0 and flow radius value of 14.0 to 24.0 mm measured according to JIS K5701-1:2000. n EFFECT: invention provides improved quality and resolution of printed images, inclusion in them of both fine-grained and coarse-grained images with spreading width of no more than 10 mcm from prescribed sizes of printing plate under conditions of high-speed screen printing at squeegee speed of 400 mm/s. n 6 cl, 1 tbl, 15 ex |
