ABSTRACT:
To avoid the image artifacts of a uniform drop-per-pixel, a drop assignment overlap is introduced. Larger and lower drops are printed simultaneously to represent uniform gray level. The regions at which the first number of drops and the second number of drops are put down overlap. Thus, a pattern in which a uniform number of drops is put down at every pixel is eliminated, and a pattern of overlapping first and second drops is obtained.
