ABSTRACT:
In recording a color picture image on a photosensitive and pressure-sensitive recording medium, in accordance with one aspect of the invention, a light carrying an image of an original is exposed on the recording medium through a main optical path and a light carrying an image of a supplemental sheet is multiplexedly exposed on the same recording medium. The recording medium is thereafter pressure-developed to provide a visible composite color image. In another aspect of the invention, two mask members are provided, one for a half-tone image of the original and another for a fine line image thereof, wherein a light is exposed on the recording medium through the respective mask members to form a latent image in accordance with a light shielding image formed on the mask members, whereby reproducibility of the original image is improved.
