  • Patent number: 6707572
    Abstract: A computerized method for controlling the density of pixels deposited by a print engine includes the steps of: (a) obtaining a two-dimensional pixel map of an image to be printed; (b) comparing a value of a first pixel element in the pixel map with values of pixel elements adjacent to the first pixel element in the pixel map; (c) changing the value of the first pixel element responsive to a determination, in the comparing step, that a predetermined number of pixel elements adjacent to the first pixel element have the same value as the first pixel element; and (d) dispatching the pixel map to a print engine. The comparing step (b) includes the steps of assigning like-value pixel elements immediately adjacent to the first pixel element a first weight, assigning like-value pixel elements diagonally adjacent to the first pixel element a second weight, different than the first weight, adding the assigned weights together to produce a total weight, and testing the weight against a predetermined threshold.
