Printing form precursor having indicia and a method for preparing a printing form from the precursor

摘要

The present invention relates to a photosensitive printing form precursor and a method for forming a printing form from the precursor. The precursor includes a support and a layer of a photosensitive composition adjacent the support, in which at least one indicia is disposed between the support and the photosensitive layer. The indicia identifies the precursor, is retained throughout a multi-step process to convert the precursor into a printing form and in the end-use of the printing form.

主权项

1. A printing form precursor comprising:
a) a support; and, b) a layer of a photopolymerizable material comprising a binder, a monomer, and a photoinitiator that is sensitive to actinic radiation, the photopolymerizable layer having a front side that is capable of forming a printing surface and a backside that is opposite the front side and adjacent the support; wherein at least one indicia of a text or graphic is disposed between the support and the backside of the photopolymerizable layer and is visible to a user without the need for an added or specialized scanning device to detect said at least one indicia.
