Title: LASER IMAGED PRINTING PLATES
Abstract:
Laser-imageable flexographic printing plates and a method of making same are disclosed. A thin masking layer comprising insoluble particles is laminated to a photopolymer layer. The insoluble particles in the masking layer roughen the photopolymer surface when the masking layer is laminated to the photopolymer surface. The masking layer is selectively ablated from the photopolymer using a laser operating at a selected wavelength to create an in situ negative. The resulting negative can be subjected to typical UV flood exposure and development.
