Patent ID: 8137896

Claim:
A method of making an image comprising: A) imagewise exposing a negative-working lithographic printing plate precursor using imaging radiation to provide both exposed and non-exposed regions in the imageable layer, said lithographic printing plate precursor comprising a substrate and having thereon an imageable layer comprising: a free-radically polymerizable component, an initiator composition that is capable of generating free radicals sufficient to initiate polymerization of said free-radically polymerizable component upon exposure to said imaging radiation in the presence of a radiation absorbing compound, a radiation absorbing compound having a λ max of from about 700 to about 1400 nm, and a primary polymeric binder that comprises recurring units derived from one or more N-alkoxymethyl(meth)acrylamides in an amount of from 20 to 75 weight %, based on the total dry primary polymeric binder weight, wherein said primary polymeric binder is present in an amount of from about 12 to about 70% based on total imageable layer dry weight, and B) applying a single silicate-free and metasilicate-free processing solution off-press to said imaged precursor to remove predominantly only said non-exposed regions and to provide a protective coating over the resulting imaged and developed surface having exposed and non-exposed regions, said processing solution having a pH of from about 3 to about 11 to provide a lithographic printing plate, the lithographic printing plate requiring no separate gumming and rinsing steps before it is used for lithographic printing.
