  • System and method for reducing visibility of registration errors in an image to be printed using a digital color printer by convolution with a laplacian kernel
    Patent number: 8199359
    Abstract: A system and method for trapping in electrophotographic color printing and related technologies for printing or display in which the final image is an overlay of multiple components subject to alignment errors. Trapping is based on the cyan (C), magenta (M), and black (K) planes. There are four steps as follows: detect object edges on each of the four color planes; detect coincident and opposing edge transitions on each pair of planes (CM, CK, and KM); determine which plane to trap, i.e., to extend object across edge; and generate trap on that plane using a simple trap generation rule and a single trap generation rule.
