The article examines the viscosity, stickiness and fluidity of metallized paint, which contains rosin from cherry tree resin, linseed and soybean oil, microcalcite, aluminum powder, and alkyd varnish. To determine the correct selection of paint composition in order to obtain a rich print, it is necessary to know its viscosity, which characterizes the internal friction of the liquid when they move mutually under the influence of mechanical stress. Since matching the ink viscosity to the printing method will minimize color deviations on the print, reduce the consumption of basic materials and increase the economic indicator. Reducing paint consumption is economically and technologically beneficial, since the drying time and the time for fixing the paint layer are reduced. To obtain an even paint layer without roughness on the surface of the printed material, the degree of paint grinding, determined according to GOST 52753-2007 by the depth of the groove of the “Wedge” device in micrometers, must be within the standard, which indicates the absence of coarse, unground particles of pigment in the paint composition. The behavior of the ink during the printing process and the quality of the print are affected by the stickiness of the ink, otherwise adhesive-cohesive properties, determined according to ISO 12634:1996 using a tack meter. Plucking of paper fibers occurs when paint is highly sticky. To minimize color deviations and quickly fix the paint, its internal structure must have sufficient fluidity. As a result of the study of the structural and mechanical properties of the paint of the new composition, the correctness of the selection of the composition of the binder, pigment, and various additives was revealed, since the values of viscosity, stickiness, fluidity, and grinding degree are identical to the values of the paint produced in China and are within the standard.
