Abstract

The invention discloses a computer-to-plate flexible plate and a production method thereof. The flexible plate comprises a supporting body, a photosensitive elastomer layer, an anti-adhering layer and a protection film, a plate material is directly scanned through a computer and then cleaned with water or a solution prior to being dried in hot wind to be made into a printing plate of the flexible plate, scanning of the computer is performed before stripping of the protecting film or after stripping of the protecting film, the photosensitive elastomer layer is highly sensitive to purple light and ultra violet and can be sufficiently cross-linked and solidified; the protecting film is a transparent thin film. Dynamic integration of rapid laser plate production and fine network reduction is realized, and adhesive strength of the photosensitive elastomer layer of the flexible plate is good.

Description

technical field [0001] The invention relates to a computer-to-plate flexible plate and a preparation method thereof, in particular to a computer-directly imageable flexible photosensitive resin plate and a preparation method thereof. Background technique [0002] At present, flexographic printing is widely used in the printing of cartons, flexible packaging, labels and other easily deformed or soft substrates. [0003] Usually, a film with patterns or characters is placed on an unexposed flexographic plate, exposed to ultraviolet light, and the transparent part of the film passes through ultraviolet light, and the photosensitive elastomer undergoes cross-linking and curing. The area that does not pass through the ultraviolet rays cannot undergo cross-linking reaction, and the difference in solubility in the developer is used to develop a relief image containing text patterns. The developed plate is dried, debonded, and post-exposed. The prepared plate is fixed on the cylin...
