  • Additive color printing method and apparatus
    Patent number: 4050808
    Abstract: Illumination for printing, including that reflected from a color negative, is sensed as to spectral content by a plurality of light-responsive sensors of mutually-exclusive spectral characteristics. That response is employed to control the spectral characteristic of the illumination for printing, as may be desired. The illumination for printing is homogeneously integrated as to intensity and spectral content prior to impinging upon the color negative by a hollow housing having both specularly and non-specularly reflective surfaces.
