Patent ID: 7401552

Claim:
A method for manufacturing a flexographic printing master comprising the steps of: (a) providing an ink-receiver surface; and (b) jetting a curable jettable liquid having a viscosity of not more than 100mPa.s at a shear rate of 100s −1 and a temperature between 15 and 70° C. on said ink-receiver surface, said curable jettable liquid comprising at least one photo-initiator, at least one monofunctional monomer, at least 5 wt % of a polyfunctional monomer or oligomer, at least one monomer or oligomer with at least one acid functional group and at least 5 wt % of a plasticizer, wherein the weight percentages of the polyfunctional monomer or oligomer and the plasticizer are based on the total weight of the curable jettable liquid, wherein the curable jettable liquid after curing possesses an elongation at break of at least 5%, a storage modulus E′ less than 200 MPa at 30 Hz and a volumetric shrinkage less than 10%, and wherein the curable jettable liquid does not contain an elastomer.
