<p>PURPOSE:To synthesize a negative film A with a negative film B by a scanner for printing plate engraving by synthesizing respective image data of two originals near a repeating point and then outputting the synthesized image of the two originals to the surface of an exposing drum of the scanner. CONSTITUTION:A scanner part 1 is constituted of a decomposing drum 2 for setting up an input original, an exposing drum 3 for setting up an exposure film, a reading head 8 for reading out the image of the input original, an input interface 9 for converting the image read out by the head 8 into an electric signal and forming image data of yellow (Y), Magenta (M) and cyan (C), and an interface 10 for outputting image data formed by the input interface 9 and synthesized by an image synthesizing part 20 to the surface of the drum 3 through an exposing unit. Consequently, a film negative plate for an endless plate on which an extremely accurate image having an inconspicuous seam is formed can be formed within an extremely short period.</p> |
