PHOTOPOLYMER PLATE AND METHOD FOR IMAGING THE SURFACE OF A PHOTOPOLYMER PLATE

摘要

A flexographic printing plate and a method for making a flexographic printing plate. According to one aspect, the method comprises the steps of providing a photopolymer substrate having a top surface pretreated with a non-gelatinous inkjet receptive coating; image-wise ink jetting an inkjet composition onto a portion of the pretreated surface of the photopolymer substrate to provide a photomask layer; exposing the photopolymer substrate to ultraviolet light to cure an unmasked portion of the photopolymer substrate; and processing the photopolymer substrate under conditions effective to render the cured unmasked portion of the photopolymer layer into a raised image surface suitable for use in a flexographic printing process.
