Flexographic printing is currently one of the leading technological processes for manufacturing flexible packaging from film materials for various groups of consumer goods. UV inks are gaining particular popularity due to their environmental benefits, fast curing, and the ability to print on various non­absorbent substrates. The article presents a comparative study of two generations of INXFlex™ UV Euro series UV inks for narrow­web flexographic printing.

This study explores the influence of self adhesive printing sleeve hardness on the quality and stability of the flexographic printing process. The primary objective is to improve process predictability and print consistency by examining how different sleeve configurations affect key print parameters. Specifically, the research compares self­adhesive sleeves of varying hardness levels with a standard sleeve setup using conventional mounting tape.

This study analyzes the factors affecting the printing process on wide­format highspeed flexographic presses equipped with a central impression cylinder. This type of printing equipment is the leading solution for the production of flexible packaging, which makes up the majority of all packaging products.

In today’s conditions of rapid development in the printing industry, the quality of printed products is determined not only by design or functionality, but primarily by the accuracy of image reproduction following the author’s original. One of the most important factors affecting the reproductive quality of offset printing is the stability and pre­dictability of the colour transfer process, considering the characteristics of the printing plates used.

The article contains the results of the research on the influences of different concentrations of working solutions of the enzyme product «Enzymnyi» on microbial biofilms Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus cereus.
