Abstract

The article presents the results of a study of the relationship between the structural parameters and properties of the sealed material on an absorbent and non-absorbent basis by methods of fractal theory. Assessing the effect of the fractal structure of the printed contact surfaces on the transfer of ink, it is necessary to take into account the heterogeneity of their structure. For this purpose, profilograms were obtained, the values of the arithmetic mean deviation of the profile, the height of the irregularities at 10 points and the greatest height of the profile were determined. The calculation of the fractal dimension of the surface structure of materials, characterizing the entire surface area under study, and not its specific points, as well as the ink capacity, reflecting the quantitative relationship between the microgeometry of the surface of the materials being sealed and the perception of ink directly in the printing process, is performed. Graphs of the dependence of the amount of paint on the sealed surface with different absorbency on the thickness of its layer are constructed. Saturation and paint transfer coefficients were also calculated, taking into account the influence of the fractal structure of materials on the transition of paint. It was concluded that there is a relationship between the structural parameters and the properties of the sealed material.
