There is a wide range of printing inks for flexography, which affects the quality of a printed image on the print [4].Flexography is traditionally considered a comparatively simple printing technology. However, as the requirements for the flexographic product quality increase, there emerge certain problems that need to be solved and explored. That is why defining the effect exerted by some factors on the technological process of printing plates manufacturing, as well as and printing, can resolve the issues related to ensuring the quality of prints made by flexographic printing. Often, there are problems related to the correct reproduction of elements in the image with different complexity of the pattern, which affects the stability of the printing process, as well as obtaining high-quality prints. The use of various materials for printing flexographic images requires the study into their surface structure before and after the application of the ink and is of paramount importance for obtaining prints with the appropriate optical and operational characteristics.

An analysis of modern designs and technologies for the production of printed books reveals that a significant part of semi-finished products in bookbinding must undergo a process of gluing. It requires an additional operation of drying, which under natural conditions is a time-consuming process. It is known that natural drying of glued joints is difficult to

The paper presents a model of factors that influence on the quality of relief-dot Braille inscriptions in their intensive use by blind people. It was constructed matrix of depending and distancing by using a directed graph. It allowed establish a hierarchy between studied criteria’s of impact the on durability of relief prints. It was developed a basic structure of digital system of assessment the conformity of Braille symbols to applicable international standards and definition of operational stability.
