| 摘要 |
The invention provides an improved method for producing halftone images with digital halftone cell dimension and orientation to match a desired ideal halftone cell in an ideal halftone grid by choosing a reference ideal halftone cell size having a predetermined number of pixels and comparing the number of pixels in the newly selected halftone cells to the reference, thereby making the number of pixels in all ideal cells to be equal. Methods are provided for controlling the assignment of pixels on the boundary line between ideal halftone cells while avoiding pixel clustering. RSB/8514-24/PO12.PAT 66
