A method for printing multiple binary bitmaps ( 10 ) with an original density level ( 12 a) and a color ( 18 ), wherein the color ( 18 ) is the same for all the multiple binary bitmaps ( 10 ), by combining "n" number of binary bitmaps into "p" bits of a multibit image forming a "p" bit image ( 20 ), identifying at least one overprint ( 24 a), predicting an overprint density ( 26 a) for each overprint, calculating a set of exposures ( 28 ) needed to image each overprint density ( 24 a) and original density ( 12 a), setting a maximum exposure level ( 30 ) that is a number greater than or equal to the maximum of the set of exposures ( 28 ), calculating pulse width modulation levels ( 30 ) for the set of exposures ( 28 ) using the set maximum exposure level ( 30 ), and printing the color ( 28 ) at the set maximum exposure level ( 30 ) using the pulse width modulation levels ( 30 ) for each level of the "p" bit image ( 20 ) in a single pass.
