A multi color printing method employing a color printer capable of non-overlapping color printing using M colorants, where M is greater than two, includes the steps of: providing a digital color image having multi-bit color pixels; separating the digital color image into three multi-bit color primary components; converting each multi-bit component into a 1-bit component using a digital halftoning technique; assigning a single printer colorant to each output image pixel based on the 1-bit color components. The printer colorants are assigned by: dividing the image into n-tuples, each pixel in an n-tuple having a unique designation N; assigning N-member combinations of N-1 printer colorants and no colorant that appear as combinations of 1-bit color components; and setting an output to the Nth member of an N-member combination based on the corresponding combination of 1-bit color components. The image is then printed using the assigned colorants.
