PURPOSE:To set a dot film on an original platen and expose it in the light room by dividing an optical path extending from a light source to a color photosensitive material by a light shielding means arranged in the middle, and putting the optical path on the light source side in the light room and carrying out exposure. CONSTITUTION:A shutter 27 is fixed to a light shield plate which sections the internal space of a frame body 10 and divides the optical path of exposure to the side of the light source 22 and the side of the photosensitive material 50, thereby enabling the optical path to the side of the light source 2 to be placed in the light room. In this case, the shutter 27 and its fitting plate form the light shield means, but a light shield means independent of the shutter 27 may be prepared separately and the fitting plate may be constituted movably by using a bellows or flexible curtain body. Consequently, color proof of different size can be formed speedily in the light room through easy operation. |
