摘要
Improvements in bit-image quality in printing systems is achieved by providing several different pattern matching processors. Each pattern matching processor comprises a lookup table of patterns and corresponding replacement image patterns. A source image is modified by replacing areas in the source image that match patterns with the corresponding image patterns. Pattern matching processors are chosen depending on: the type of image being processed, input from the operator (user), feedback from the xerographic processor, and the color of the image. A user interface is provided which allows a user to download template and pattern data for each pattern matching processor. Pattern matching can be used to correct single-bit, half-bit, line-growth, xerographic effects and aliasing errors, and to provide control of print quality to the user.
