Document Type and Number:
WIPO Patent Application WO/2023/189272
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a production method in which printed matter of stable quality is obtained even by continuous printing, by combining a specific flexographic printing plate with an actinic-ray-curable ink. In this production method for printed matter are used: a flexographic printing plate comprising a substrate and a resin layer having a printing relief; and an actinic-ray-curable ink comprising at least one polyfunctional (meth)acrylate and a pigment. The production method for printed matter satisfies the following (A) to (C). (A) The resin layer having a printing relief includes a compound A having an SP value, as calculated by the Fedors method, of 10.0 or greater, in an amount of 30 mass% or larger. (B) The polyfunctional (meth)acrylate has an SP value, as calculated by the Fedors method, of 8.0-9.5. (C) The ink has a content of the polyfunctional (meth)acrylate satisfying said SP value of 40-85 mass%.
