Claim One:
1. A method, comprising: a printer generating a dither matrix of threshold values; and the printer filtering the threshold values in the dither matrix to generate a filtered dither matrix of filtered dither values by: determining a region of dither values in the dither matrix that surrounds the value being considered, wherein the dither values in the determined region comprise one of dither values in a first portion of the region within the dither matrix or a wrap around dither value in a second portion of the region that extends beyond the dither matrix; using an offset value to determine one wrap around dither value, wherein repeated instances of the dither matrix are designed to be applied to an image by forming a tile pattern of the repeated instances of the matrix over the image pattern, and wherein the repeated instances of the matrix in the tile pattern are offset in one direction by the offset value; and performing an operation on the determined dither values in the region to determine a filtered value for the dither value being considered.
