Abstract
A halftone screen is presented for use in combination with reproduction devices that are capable of rendering more than two tone levels. The screen is optimized to minimize both tone and color shift in the presence of variations in the printing process. The intermediate density levels, which are assigned to a minority of the microdots within each halftone cell, are different within adjacent halftone cells. FIG. 9
