Khariv M. Improving the technology of manufacturing screen printing plates by laser engraving for Braille printing.

In the dissertation work, the current state and the first perspectives of creating an information environment of Braille for integration into society of people with vision problems, technologies of reproduction maintaining relief-point images and the prospects for their development. Improved technology for the production of stencil printing plates laser engraving based on the developed photopolymerization braille composition. A study of technological, physicochemical, physical and metechnical properties of the developed plate material for screen printing forms for laser engraving, reproduction-graphic and printing-technology technical parameters of shapes and relief-point images. The studies carried out in the conditions of enterprises confirm that the improved technological process of manufacturing screen printing laser engraved shapes for high quality Braille and has a high technical and economic efficiency. Keywords: screen printing plate, laser engraving, screen printing technology, wear resistance, ink capacity, image quality, relief-dot images, Braille font.
