PROBLEM TO BE SOLVED: To provide a space layout unit that permits a layout change to the utmost while preventing mismatching between a progressive version and a monochromic version. SOLUTION: The space layout unit 24 of this invention is provided in a composition terminal 9. In the case a color progressive version is outputted earlier than a monochromatic version including an article, since revision of a color image and the layout in an in-slip including the color image is inhibited, no mismatching is caused even when the progressive version is synthesized later with the monochromatic version. Since the rearrangement of the article is permitted when the position of the color image is unchanged even by rearranging the article, even when a new article is intruded like a newspaper space, the revision of the layout is possible. Even when an in-slip is placed in the space, if a relative position of the color image in the in-slip is unchanged, since the rearrangement of the article in the in-slip is permitted, the layout correction of the in-slip is facilitated without causing mismatching with the progressive version.
