Patent ID: 7253924

Claim:
A method for printing multiple binary bitmaps having an original density level and a color, wherein said color is the same for all said multiple binary bitmaps comprising: (a) combining “n” number of binary bitmaps into “p” bits of a multibit image forming a “p” bit image; (b) identifying at least one overprint; (c) predicting an overprint density for each overprint; (d) calculating a set of exposures needed to image each overprint density and said original density; (e) setting a maximum exposure level which is a number greater than or equal to the maximum of said set of exposures; (f) calculating a pulse width modulation level for said set of exposures using said set maximum exposure level; and (g) printing said color at said set maximum exposure level using said pulse width modulation level for each level of said “p” bit image in a single pass.
