Exposure control system for color printers |
摘要 |
An exposure control system for color printers having electro/optical means for spectral analysis of different types of original material for printing to determine different spectral coefficients for each material. Each coefficient is classified according to a reference range of values, each range being associated with a different original material. Photoelectric means are provided to determine the color densities of an original and a store stores sets of exposure parameters, each set being associated with a different original material. Automatic selection means responsive to the classification is provided to select whichever parameter set is associated with a coefficient reference range in which the coefficient has been classified during classification.
