Abstract
A presensitized printing plate intermediate having an image mask on a UV radiation transparent removable coating layer; and a printing plate produced directly by reactants which polymerize alone or in combination with other reactants precoated on the plate substrate to form a printable hard resin image. A method of digitally forming an image on said printing plate intermediate.
Claims13
A method for forming an image on a printing plate, the method comprising:
- depositing a liquid comprising at least one reactant of a resin-producing reaction mixture onto the surface of the plate, whereby the reactant deposited onto the surface of the plate comes in contact with a remaining reactant or reactants necessary to complete the resin-producing reaction mixture;
- wherein:
- the liquid is deposited in a predetermined image producing manner using at least one ink jet printer head;
- and
- the resin-producing reaction mixture hardens on contact with the plate.
