Here, in particular, when the original is color-separated, the photo data for the display device, the photo data for the color comp output device,
It is decomposed and stored at five image densities: photo data for a plate-making device, photo data for a plate-making device corresponding to scale conversion for enlargement, and photo data for a plate-making device corresponding to scale conversion for reduction. This image density is decomposed as 72 DPI as display device photographic data and stored as RGB data.

At the time of outputting this printing plate, the photo data (32S-S) for the plate-making device is used as the photo data (32S) in the same manner as the above-mentioned output of the color comp. Since S) is color-corrected according to the type and model of each plate-making device (90), it is output in an accurate color tone (color separation in which a printed matter of a color tone intended by the operator is printed during editing). It

Then, if the print material data (32) is used again when the same order is made again after that, the data stored in the print data storage unit (30) is called for editing, color comp output, and disassembly. It outputs the version. At that time, when the magnification is changed, if the scale conversion is 130% or 80% and there is no possibility of jaggies appearing, the photo data for the plate making device (32S-S) is used, and if the jaggies are about 160%, the jaggy is used. If there is a risk of appearing, the photo data (32S-T) for the plate-manufacturing device corresponding to the scale conversion, and if it is reduced to 50% or less, the photo data for the plate-manufacturing device supporting the scale conversion (3
