A logo on the package by the flexographic printing was widespread with the development of engineering and technology. Flexographic printing owes its name to the application of elastic-elastic plates, which are the hallmarks of this printing method. All machinery platemaking, as for drawing the logo on the packages, and for other printing operations for printing high attributable mainly to flexographic printing. The sequence of a conformal coating process for the logo on the package as follows: 1.Izgotovlenie cliche of different materials (tsink. magnesium, copper) with a negative film, etched in the usual way or engraved with a mirror image, suitable for indirect printing (printing press). 2.Tisnenie rigid metal plate matrix (phenolic resin impregnated cardboard), which serves to mitigate cliche to stretch the printed form. 3.Izgotovlenie rubber printing plate by vulcanization of natural or synthetic rubber: for heating and high pressure meter is filled matrix liquid rubber, while receiving printed form with a mirror image.
Pre-press printing the logo on the packages by using the special negative film with a matte top side and densitometric density of at least 4.0. The negatives are exposed with ultraviolet light directly on the photopolymer printing plates. Oteksponirovannye sites photopolymer plates harden, then kA unexposed areas remain soft and washed until the speaker of the relief (photopolymer printing plate). Photopolymer plates are flexible originals printed forms, made "directly" without the matrix. Direct exposure ensures sharp contours of the halftone dots, lines, letters and graphic surfaces. Photopolymer printing plates are proven in fleksograskoy printing on packages, and other surfaces, especially for the rasterized image is four-color scale. In the selection screen ruling there was no mechanical limitations in comparison with etched or engraved metal plates.
