Abstract: A digital color printer system measures and provides a digital display for the primary color values of incident light from a colorhead for the system. The color mixture of light from the colorhead can be programmed in accordance with selected color values for the accurate reproduction of a print from a negative. The color printer system includes a microprocessor for carrying out various program functions for calculating, utilizing, and storing color value and exposure data, and a combined accessory unit including a keyboard, a input/output device, and a color analyzer probe interfaced with the microprocessor.
