Abstract

In a disclosed color image recording apparatus, an elongated, web-like continuous intermediate image sheet is used as a master mask plate for forming a latent image of an original on a photosensitive pressure-sensitive recording sheet. On the master mask plate, there are separately recorded three images of one of the three color components, i.e. blue, green and red. The recording sheet is exposed to light through the respective mask plates to superpose the latent images thereon. The respective color latent images are formed in a predetermined order. The superposed latent images thereon are then developed under pressure to provide a visible image. Since the order of the latent image formation is not interchangeable, a bar code representing the order thereof is printed on the mask plate, whereby upon reading the bar code with an optical reader, the latent images are formed in the predetermined order on the recording sheet even if the mask plate is inserted in reverse order. The bar code may further contain an information regarding exposure condition, so that the exposure condition which varies depending upon the kind of the intermediate image sheet can automatically be controlled in …
