Claim 8:
9. A method of adjusting a phase shift between pixels in digital lithography systems, the method comprising:
projecting a first light beam onto a first spatial light modulator pixel, wherein the first spatial light modulator pixel directs the first light beam onto a substrate during a digital lithography process, wherein the first light beam comprises a plurality of components comprising:
a first component having a first wavelength that generates a first phase shift that is greater than a preselected phase shift; and
a second component having a second wavelength that generates a second phase shift that is less than the preselected phase shift;

projecting a second light beam onto a second spatial light modulator pixel, wherein the second spatial light modulator pixel directs the second light beam onto the substrate during the digital lithography process; and
controlling intensities of the plurality of components to generate an effect on the substrate that approximates the preselected phase shift.
