Abstract
The invention relates to a method for preparing a relief printing plate from a printing plate precursor wherein at least an end of the precursor is attached to a leader forming a composite printing form precursor that securely mounts the precursor in a treatment processor. The present method advantageously allows for all or substantially all of the area of the precursor to be utilized for forming the relief surface suitable for printing.

A method for preparing a relief printing plate from a printing plate precursor having a leading end, a trailing end, and between the leading and trailing ends a photopolymerizable layer adjacent a base support, the photopolymerizable layer having an area that is adapted to form a relief surface suitable for printing, the method comprising the steps of
- a) attaching a first leader in an extending relation to one of the leading end or trailing end of the precursor, wherein the first leader having a first end, and opposite the first end, a second end adhesively coupled to an exterior surface of the support that is opposite the photopolymerizable layer, and the first leader and the photopolymerizable layer do not overlap;
- b) mounting the precursor with the extending first leader onto a support member of a processor by securing the first end of the first leader to the support member;
- and
- c) treating the photopolymerizable layer of the precursor forming a printing plate having a relief surface;
- wherein greater than 90% of the area of the photopolymerizable layer can be utilized to form the relief surface suitable for printing.
