ンキ供給計ヲ自動的に調整するシステムが開発されてい
る。In recent years, in order to automatically adjust the amount of ink supplied from the inkwell of an offset printing machine, optical scanning of the printing plates for each color has been introduced before the start of printing. By pressing the ink adjustment key on the ink fountain, measure the area ratio of the printing area of the printing plate every 1j, and use this measurement data to press the ink adjustment key IJ on the printing plate.
A system has been developed in which the ink A adjustment key is manually operated on the roll device t to automatically adjust the ink supply meter.

必要となる。Furthermore, when measuring the area ratio of the image area of an off-cent printing plate, if it is a four-color printing machine, it is necessary to measure four printing plates: a clear plate, a red plate, an eye plate, and a black plate. There is power, again 4
Even if it is a color printing machine, if it is an offset roll-fed rotary printing machine, eight printing plates will be attached because the front side of the printing paper is printed at the same time, so it is necessary to measure eight printing plates. Become.

測定しているのが現状である。In addition, since the area ratio measuring device measures 4 or 8 printing plates as one set, we will start measuring from now on.
1) Measure each printing plate by inputting the printing color of the printing plate, or whether the front or back of the printing paper is printed 1-color, into the measuring device from a keyboard or the like before measurement, or Currently, printing plates of each color are measured in a predetermined order using a measuring device.

である画線部面積率とが喰い違ってしまうことになる。However, specifying the color of the printing plate and specifying the printing from the keyboard etc. when measuring the surface rate is surprisingly troublesome, and there are many visual differences between the printing plates. Therefore, operators are used to incorrectly specifying the printing color of the printing plate, and there is a risk that each printing plate and the printing area ratio, which is the appearance data, may be different. On the other hand, 1lI18i@ which is predetermined by the measuring device
For those that measure printing plates, for example, if they are placed in the wrong order on the printing plate stand, the measurement will be performed as is, and in this case, each printing plate and the print area ratio, which is the appearance data, will be measured. There will be a difference between the two.

る。Therefore, the object and purpose of the present invention is to measure the area ratio of the printing area of an offset printing plate by specifically identifying the discrepancy between the printing color of the color printing plate and the printing color of the output data. For example, where should you measure the strength? Is this the purpose of an offset printing plate that actually measures the red plate and the area ratio of the image area of the ah plate is not output as that of the dark plate? In the present invention, a mark for specifying the printing color of the printing plate is provided outside the effective picture area of the offset printing plate, and this color specification mark is placed on the offset printing plate at a predetermined distance from a certain reference point. It is an offset printing plate, expressed by the presence of lines.
以下に本発明を図面の実施例に基づき詳細に説明才ろ。The invention will be explained in detail below with reference to embodiments of the drawings.

出した余白部（２）である。As can be seen in Figure 1, the offset printing plate (hereinafter simply referred to as the printing plate) (P)K has the image area (low reflectance area) where the image to be printed is generally green in color and the aluminum substrate exposed. The effective pattern area (1) surrounded by the dashed dot line (3) is formed by the non-image area (high reflectance area) that exhibits a silver color, and the area outside the dashed dot line (3) is made of aluminum. This is the blank area (2) where the base material is exposed.

This data is received by an electric conversion element, subjected to K A/D conversion, and then a pulse signal is supplied separately. Since this data is a high reflectance area, it is possible to distinguish between an image area and a non-image area for each unit pixel. The magnitude of the signal is determined by the abundance ratio, and in the scanning process, the 100-print area (solid area) (12;) and the 0% image area (I

For calculation 1, a unit pixel is determined by a pulse emitted from a pulse generator or the like. Therefore, by counting the pulses emitted from the start of scanning, it is possible to determine which position on the printing plate is being measured.For example, in Fig. 1, the main scanning by the laser beam is performed in the vertical direction. Sub-scan (
Assuming that the feed is performed in the horizontal direction, by inputting the plate size in advance, it is possible to know at what pulse number the point (A) at the lower end of the center @ (4) is irradiated by the laser beam. In this embodiment, the /f mark is provided as described below based on this point (A).

An area (131) should be provided on the left side of this center line to indicate the 0-related image area.This will determine how many pulses before or after the reference point (A) is the ioo% image area, and the 0% image area. It is possible to determine whether it is an image area and to import the data corresponding to the number of pulses as calibration data.

ろことで表現される。Areas (1b1, (17), (18), (19), areas (20), t21L (22), (23) are where print color designation marks 0.A for front and back sides are to be formed, For example, let's assume that they correspond to the clear version, red version, eye version, and sumi version π, respectively, and this printing plate with this mark (2)) in the area f161 prints on the front side of the printing paper,
And it turns out that it is the key version, and area +2 + r
It is understood that the printing plate with the vc mark FM+ was printed on the back side of the printing paper, and was a red plate. In this way, in this embodiment, one mark (1) is placed on both the front and back sides of the printing paper. This serves both as a print surface designation mark that designates whether or not the print is to be printed, and a print color designation mark that designates the print color. In addition, the previous word's black mark (Kan) is expressed by forming a drawing part in the area.

することができる。Since the distance of each of these regions from the center line is determined, it is known how many pulses 1" that region is located from the reference point (A+), and therefore, the printing plate π vs. 1-L laser If the printing area is measured at a portion corresponding to the number of pulses corresponding to each area in the scanning path of the beam, then it is possible to determine what color this printing plate is in that area and the front and back sides of the printing paper. The arithmetic processing unit in the measuring device can recognize which one is the printing target, and accurate image area ratio data can be output.

The laser beam is located at a predetermined distance from the curvature, so that the scanning spot of the laser beam always exists in one of them in the course of a number of pulses corresponding to the distance of the sled. each) number of curls? 61. By storing the information in the printing device and detecting the presence or absence of the printing area at that Norms number, it is possible to recognize the printing color and printing surface of the printing plate.
