Laser print apparatus with toner explosion compensation

A method for performing toner explosion compensation on image data, the method comprising:

• loading a portion of the image data into a storage element;
• comparing a window of the portion of the image data to a toner explosion pattern as the window is moved across the portion of the image data such that image data is not compared to a toner explosion pattern when the window is located at a position such that at least one changeable pixel of the window is loaded in a boundary position of the storage element;
• and
• modifying the at least one changeable pixel of the window of the portion of the image data based on the comparison, when the at least one changeable pixel is contained in non-boundary positions of the storage element.

An image forming apparatus for performing toner explosion compensation on image data comprising:

• a memory for storing at least one toner explosion pattern having a plurality of pixel values, wherein at least one of the plurality of pixel values corresponds to a changeable pixel in the image data;
• a storage element comprising a plurality of positions including a first boundary position, a second boundary position, and one or more non-boundary positions, wherein the storage element is configured to load a portion of the image data into the positions;
• and
• a pattern comparator configured to compare the at least one toner explosion pattern to the portion of the image data loaded in the storage element and change the changeable pixel when the portion of the image data loaded in the storage element matches the at least one toner explosion pattern, wherein the pattern comparator does not compare the at least one toner explosion pattern to the portion of the image data loaded in the storage element when the changeable pixel is loaded in the first boundary position or the second boundary position.
