Abstract:
A method for randomly multipass printing a set of scanlines, comprising:inputting image data corresponding to the set of scanlines; dividing each scanline into a plurality of portions of pixels, each portion comprising at least one pixel; storing a start state for generating random numbers; generating a random number for each portion of pixels of the set of scanlines; determining, for each pixel of the set of scanlines, whether that pixel is enabled for a current one of a number N of passes of printing of the set of scanlines based on the random number generated for that pixel; printing the current pass of the set of scanlines based on the enabled pixels and image data associated with the enabled pixels; and repeating, until the set of scanlines is fully printed, the generating, determining and printing steps for each subsequent one of the number N of passes of printing of the image data of the set of scanlines based on the saved start state for generating random numbers.
