ABSTRACT:
A color proof making apparatus for making a color proof for forming a color image having a dye image by exposing an ultraviolet light-sensitive material to ultraviolet light through an image original, and by heating the exposed material. The apparatus includes a plurality of filters disposed in correspondence with different light-sensitive wavelength regions of the light-sensitive material and respectively adapted to transmit therethrough only the ultraviolet light of corresponding wavelength regions for exposing the light-sensitive material sensitive to the light-sensitive wavelength regions; a selecting device for selecting one of the filters which corresponds to each image original; and a driving unit for inserting the filter selected by the selecting device into an optical path leading to the image original. Accordingly, the filter is inserted accurately into the optical path, and it is possible to make a color proof with excellent color separation and high definition with a simple process.
