Patent number: 8735049Abstract: A method of making a relief printing element in a liquid photopolymer platemaking process is described. The method comprises the steps of: (a) selectively exposing the liquid photopolymer to actinic radiation through a negative to crosslink and cure portions of the liquid photopolymer; and (b) reclaiming uncured portions of the liquid photopolymer to be reused in the platemaking process. The step of reclaiming uncured portions of the liquid photopolymer comprises (i) heating the printing element to decrease the viscosity of the uncured liquid photopolymer; and (ii) removing uncured liquid photopolymer from the surface of the relief image printing element so that recovery of uncured liquid photopolymer from the surface of the relief image printing element is enhanced.Type: GrantFiled: May 22, 2012Date of Patent: May 27, 2014Inventor: Ryan W.
