Abstract

PURPOSE:To smoothly form images by providing a color discriminating means, a means splitting images into color information and a photomask continuously forming means, permitting a control means to control a cutting means, and cutting and removing photomask images selectively. CONSTITUTION:Information on red images is recorded on a thermosensible paper 5 lying between a thermal head 3 and a platen 4 through an input part 20 and a control part 19, and similarly blue and green images are recorded. One photosensitive and pressure-sensitive sheet 12 is pulled out by a roller 14 and set to a holding part 16. Images 5C on the thermosensible paper 5 on which red images have been recorded are arranged, and exposed by a light source 9C through a filter 11C. With the recording sheet 12 unchanged, the filter is switched to 11M and 11Y in that order, and blue and green latent images are drawn. Due to selective exposure, microcapsules in three colors are selectively cured, and crushed by an pressure developing part 17, then the recording sheet 12 exhibiting colorful images is ejected to a tray 18. The thermosensible paper 15 possesses positioning marks LC-LY in one-image units, is sent with the aid of holes 21, is cut by a cutter 7 and is taken out. By using this constitution, the cutting and removing position of a mask original plate can be readily switched in accordance with needs such as plural color splitting or monochrome.
