Nykyruy V. Improving the technology of manufacturing of flexographic printing plates by direct laser engraving

Problems and prospects of manufacturing of flexographic printing plates (FPP) is analyzed in the manuscript. It is established that modern technologies of FPP based on materials able to photopolymerization have a number of disadvantages associated with many-stages process, quality control problems of individual process operations, and so on. So, actual is to improve the process of manufacturing FPP by direct laser engraving by improving the parameters and characteristics of the laser engravable devices based on fiber lasers. The upgrade of optical node of Laser Graver has been carried out by entering the telescope into the optical system. Calculation of optical parameters of the telescopic system, engineering design of two-multiple telescope and its manufacturing has been carried out and then it has been adapted in the optical system of the device, allowing doubling the recording resolution of the equipment.
