We have developed a novel digital color printer using silicon microdisplay as the image generator. The digital image data were written into the silicon microdisplay in color sequence and projected onto a Polaroid 500 film for additive color printing. 30-bit full color was achieved through the color and field sequential exposure technique. Resolution of over 300 color pixels per inch was obtained with the silicon microdisplay of 1024 x 768 pixels.
