The standard form of the bar code symbol for the common product code has been described. However, the present invention is not limited to the above-mentioned JIS, but is used for a product such as a product. United States m ⁰ ·

UVM technology — EAN of mouth-opening standards, plus the power of the manufacturer; independently determined symbol codes — such as codes — for the creation of printing masters for all symbols You can use it as it is. The gist of the photographic film described in the description of the invention does not change even if it is changed to a printing original plate, and is a matter within the gist of the invention.

As described above, the width of the black bar of the printing original plate to be overprinted is set to the basic dimension (0,35 for Jis) or a predetermined magnification thereof. Expanded or reduced module standard dimensions (similar for Jis

It is composed of 22 steps from 0,26 to 0,65), and has a print finish. This is because in this example, the printing original plate made by the reprinting machine was used as the reference printing original plate, and the original printing plate was then printed on the printing plate material to produce relief printing or intaglio printing. It is self-evident that the printed bar becomes thicker and the reading trouble occurs. Therefore, in order to bake the code symbol on the printing plate material, the printing thickness determined by the printing means from the bar of the above-mentioned reference original plate is determined in advance. It is necessary to have a so-called film master of the final dimensions that has been subtracted and corrected accurately. Prepress this film master (L5)

In other words, a device * that corrects by subtracting the printing weight from the reference printing original plate * is a plate correction, which is another part of the present invention.

¾ Λ. The plate making machine described with reference to Fig. 1 to Fig. も is used to make a plate master from the beginning. This is also possible; the film master has been changed to an offset for some reason, such as flexographic printing using rubber letterpress. I have to rework each time, such as in case of a storm. Therefore, in principle, the plate making apparatus of the present invention divides the process of preparing the printing plate into five major parts, and the first process is used as the plate making of the reference printing plate common to all printing methods. As a ^{second step} , test printing using the appropriate printing method according to the printing method decided to be adopted! Then, the printing weight is measured from the result, and then the bar width reduction amount and the enlargement ¹⁵ ratio are obtained. In the fifth step, the film master was modified using the above-mentioned sack-plated standard master as the manuscript and precisely correcting it by the bar width reduction amount obtained in step 2 above. Ο Fig. 7 is a plan view of the plate compensator m as an embodiment of the above-mentioned fifth step of the present invention ∞ Fig. 8 is a part thereof.
