Claim 0:
1. A method of making a printing form precursor comprising:
a) applying a photopolymerizable composition comprising a first binder, a monomer, and a photoinitiator onto a support to form a photopolymerizable layer;
b) printing an ink onto a surface of the photopolymerizable layer opposite the support to form a pattern layer;
c) applying an infrared ablation composition forming an infrared ablation layer on the photopolymerizable layer over the printed pattern layer, the infrared ablation composition comprising (i) at least one infrared absorbing material; (ii) a radiation opaque material, wherein (i) and (ii) can be the same or different; and (iii) at least one second binder; wherein the infrared ablation layer is for forming an in-situ mask by infrared ablation during conversion of the printing form precursor to a relief printing form.
