METHOD FOR PRODUCING FLEXOGRAPHIC PLATE ORIGINAL FOR LASER ENGRAVING

摘要

In order to provide a method for stable production of a flexographic printing plate precursor for laser engraving, this invention proposes a method for production of a flexographic printing plate precursor for laser engraving including at least the following steps to be carried out in this order:
(1) a step for separately preparing a plurality of fluids that are reactive with each other,
(2) a step for carrying out in-line mixing of the plurality of fluids to form a reactive resin composition,
(3) a step for casting the reactive resin composition onto a release material to form a cast film,
(4) a step for heating the cast film, and
(5) a step for removing the cast film from the release material to form an independent sheet made of the reactive resin composition.
