METHOD FOR PREPARING COMPOSITE PRINTING FORM

摘要

PROBLEM TO BE SOLVED: To provide a method for preparing a composite printing form for use in relief printing, particularly.

SOLUTION: The method is provided for preparing the composite printing form from a single precursor capable of forming a relief and a carrier. The single precursor can be a single photosensitive element or a single laser-engravable print element having a reinforced elastomeric layer. The single precursor has a size that is at least 70% of a size of the carrier. The single precursor is located on the carrier by approximately positioning the precursor on the carrier that has no registration markings. Precise registration of the single precursor is achieved by using digital information generated from a computer to form a registered image on the composite form. The method is particularly suited for preparing composite printing forms for relief printing, and in particular for preparing composite printing forms for flexographic printing of corrugated substrates.
