Abstract
The present disclosure relates to a method and system for processing isolated dots of an image to be printed by a printer. The method includes generating a random number, determining whether a target pixel is to be turned on and enabled for printing, determining a sum of pixels surrounding the target pixel in a plurality of pixels in a scanline of the image, the target pixel corresponding to an isolated dot in an input image, that are in an on state, the on state defined by a higher binary logic level relative to a binary logic level corresponding to a turned off pixel, determining a numerical value stored in a lookup table using the determined sum of pixels that are in the turned on state surrounding the target pixel as an index to the lookup table, and comparing the generated random number to the determined numerical value.
