Treatment process of flexible plate for flexography gradient printing

Abstract

The invention discloses a treatment process of a flexible plate for flexography gradient printing and relates to the field of a printing plate. The process is characterized in that a base layer surface of a flexible plate is placed under a long-wave ultraviolet lamp in a plate burning machine for irradiation; according to a to-be-printed pattern shape, an embossment layer of the flexible board isplaced in an engraving machine for engraving, a black film is removed, and a to-be-printed pattern is obtained; the embossment layer of the flexible plate is placed under a short-wave ultraviolet lampof a plate burning machine for irradiation, so the to-be-printed pattern is partially hardened; the embossment layer of the flexible plate is cleaned through a plate cleaning machine, the flexible plate is tightly attached to a plate cleaning roller, the plate cleaning roller and a non-woven fabric roller rotate relatively, in the cleaning process, a black film on the embossment layer is melted at the high temperature and then converted into gas to exhaust, and residual resin is erased through non-woven fabric. The process is advantaged in that the cleaned flexible board is fixed, the embossment layer of the flexible board is irradiated by the long-wave ultraviolet lamp, the base surface layer is irradiated by the short-wave ultraviolet lamp, so the treated flexible board is finer, higherin hardness resistance and fine and smooth in pattern.

Description

technical field [0001] The invention relates to the field of printing plates, in particular to a flexible plate treatment process for flexo gradient printing. Background technique [0002] Printed matter is more common in our lives, such as merchants' Alipay QR codes, stickers on shampoo, and stickers on shower gel. The variety and use of printed matter are relatively extensive, and the formation of printed matter is inseparable from the printing process. The development of printing process has not remained unchanged so far. On the contrary, the improvement of its printing quality is always accompanied by changes. Changes are often in two forms. One is a partial change; the other is a complete change. The printing process, whether it is a partial change or a complete change, will cause the printing effect to change more or less. The most important link in the printing process is the production of the printing plate template. The quality of the printing plate template direc...
