Abstract:
Photofinishing system with improved control, comprising:a. a light source; b. a spatial light modulator for modulating light from said source into a print image; c. a transport system for transporting a substrate on a carrier past said spatial light modulator such that said substrate receives said print image; d. a first encoder sensor attached to said carrier operable to sense movement of said carrier and to generate an image position signal; e. a second encoder sensor attached to a drive circuit of said transport system operable to sense operation of said drive circuit and to generate a motor control signal; f. a first circuit operable to receive said image position signal and adjust operation of said spatial light modulator such that said spatial light modulator modulates said print image based upon position of said substrate and desired resolution; and g. a second circuit operable to receive said motor control signal and to adjust operation of said drive circuit to coordinate movement of said substrate with said modulation of said print image.
