Abstract

The study of the effect of microheterogenicity of paper on print quality is of great importance for understanding the processes of ink transfer to the paper surface, as well as for optimizing printing processes and improving the quality of the final product. It is also relevant for the development of new types of paper specially adapted for certain types of printing, such as offset, digital or sublimation. In this article, research on the microheterogenicity of paper aims to identify the relationship between the structural features of paper and its ability to reproduce high-quality images and texts. The research methodology includes: method of microscopic analysis in natural light using a conventional microscope, studying paper microstructure in polarized light, mastering paper microstructure in the infrared and ultraviolet regions of the optical spectrum using luminescent analysis. The legislator in the field of paper and printing does not give a clear definition of paper heterogeneity. All regulatory documents require coordination of the heterogeneity of the material with the consumer, while not specifying methods for assessing cloud cover. Thus, the study of this problem is an urgent and promising direction in the field of scientific research and innovation in the production of paper and printing.
