  • Patent number: 6492095
    Abstract: flexographic printing plate having solid image areas which are covered by a plurality of very small and shallow cells similar to the ink carrying cells found in anilox ink metering rolls. These cells fill with ink during the plate inking step and reproduce solid image areas with better color saturation while at the same time reducing the halo typical of flexographic printing of solids. Associated with this plate is a method for producing the cells, including the use of an intermediate screened film and of a computer program for generating the film intermediate.
