摘要:
A color proof formation method includes the steps of bringing a first color separated film original mounted upon an original mounting table into tight contact with a photosensitive material fixed upon a mounting table, and exposing the film original; separating the photosensitive material mounting table from the original mounting table; replacing or exchanging the first film original upon the original mounting table with a second color separated film original; and bringing the second film original into tight contact with the photosensitive material. The steps are repeatedly performed a predetermined number of times so as to form a color proof. There is also disclosed a color proof formation apparatus including a suction unit for forming a suction groove, for bringing the film original and the photosensitive material into tight engagement with each orther, between the film original mounting table and the photosensitive material mounting table while the film original mounting table and the photosensitive material mounting table are close to or in contact with each so that the film original and the photosensitive material are brought into surface contact with each other, and for evacuating the air interposed between the film original and the photosensitive material so that the film original and the photosensitive material are in fact brought into tight contact with each other.
