A method and system of designing a digital halftoning screen for forming images
on output sheets according to a set of image signals. The method generates a halftone
line screen having multiple levels, each level having multiple line segments, each
line segment having an equal pre-determined number of elements. The method stochastically
assigns threshold values to pixels corresponding to a first element within the
multiple line segments of a first level and assigns a same threshold value to a
pixel corresponding to a single level to create a first element stochastic fill
sequence. The method then assigns threshold values to pixels corresponding to a
first element within the multiple line segments of the remaining levels of the
halftone line screen according to the first element stochastic fill sequence.
