た。 2. Description of the Related Art Conventionally, in the production stage of printed matter such as books, there are cases where it is necessary to produce printed matter with the same picture configuration but with different sizes. In this case, in the conventional photoengraving method, it is necessary to re-make the original photographic plate in accordance with each finished dimension each time.
Therefore, in such a case, almost the same amount of labor and materials are required as in performing a completely different type of plate making. In particular, if it is necessary to change the vertical/width ratio of the image, it will be necessary to go back and reprint the original manuscript. Recently, for this purpose, a unidirectional expansion/contraction exposure device has been developed that allows documents to be enlarged or reduced in one direction while keeping the original size in the other direction. Since the original is enlarged or reduced in only one direction, there are disadvantages in that the number of steps increases and extra materials are required.
一方、特開昭53−111803号公報に示されるよう
に、写真原版から所望の拡大率により拡大製版を
行なう方法がある。 On the other hand, as shown in Japanese Patent Application Laid-Open No. 111803/1983, there is a method of enlarging a photographic original plate at a desired enlargement ratio.

There is a light source box 4 between the two pairs of presser rolls, and the light from the light source 13 is exposed through the slit 5 to the portions of the photographic original plate 1 and the photosensitive material for duplication 2 whose film surfaces are brought into close contact with each other from the side of the photographic original plate 1. The structure is such that it can be done.

ら数10ミクロン程度の巾に設定される。 The photographic original plate 1 and duplication photosensitive material 2 can be driven independently by motors M 1 and M 2 .
M2 has variable drive speed. If the feeding speeds of the photo original 1 and the photosensitive material 2 for duplication by the motors M 1 and M 2 are the same, normal duplication is performed, but by changing the driving speed ratio of the motors M 1 and M 2 , Among the image dimensions of the image in the photographic original plate 1, only the image size in the feeding direction of the photographic original plate expands or reduces depending on the respective speed ratios, and the image size in the direction perpendicular to the feeding direction does not change. The photosensitive material 2 for duplication is exposed. The deformation rate of the deformed image in the feeding direction can be practically up to about ±20%. Any type of photosensitive material can be used as the duplexing photosensitive material 2, but if a diazo film is used, for example, a positive duplexing film can be obtained directly from a negative-type photographic original plate, and the processing process becomes easy. light source 13
Although it varies depending on the type of photosensitive material used and the feeding speed, a light source in the form of a bar long in one direction or a light source spread out in the form of a slit using a cylindrical lens or the like can be used. The width of the slit 5 also varies depending on the type and speed of the photosensitive material, but is generally set to a width of several microns to several tens of microns.
