Abstract
Laser-imageable flexographic printing plates and a method of making same are disclosed. A thin polymeric film doped with a UV absorber is laminated to a photopolymer layer. The film is 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.
