Patent ID: 8899148

Claim:
A method for printing a material onto a substrate comprising: a) providing a relief printing form from a photosensitive element comprising a layer of a photopolymerizable composition containing a binder, an ethylenically unsaturated compound, and a photoinitiator, with steps comprising: i) forming an in-situ mask having a plurality of openings through an area opaque to actinic radiation adjacent the photopolymerizable layer, the openings having a line screen resolution equal to or greater than 250 lines per inch; ii) exposing the photopolymerizable layer to actinic radiation through the mask openings in an environment having an inert gas and a concentration of oxygen between 190,000 parts per million (ppm) and 100 ppm; and iii) treating the element resulting from step ii) to form a relief structure having a plurality of raised surfaces with a line-screen resolution equal to or greater than 250 lines per inch; b) applying the material to the plurality of raised surfaces; and c) contacting the material from the plurality of raised surfaces to the substrate thereby transferring the material to the substrate.
