れている。2. Description of the Related Art Proofreading work using a flatbed printing machine requires heavy skill and is a heavy labor work that causes physical fatigue. Among them, the difficulty of securing human resources in recent years and the aging of personnel,
In order to respond to immaturity, standardization and automation of proofing work,
Labor is being reduced. For example, in automation,
An automatic ink supply device and an automatic paper feed / discharge control device have been developed.

とによって処理している。However, the registration work has not been put into practical use so far, and it is still done visually. In other words, by visually observing the displacement of the register through a magnifying glass, and based on the intuition cultivated through many years of actual work experience, the mounting position and mounting posture of the printing plate are corrected according to the displacement amount, Alternatively, the processing is performed by moving the position where the non-printed matter is placed.

のような装置で見当合わせ作業ができる。Incidentally, there is a device for aligning the paper by automatically moving the paper length on the paper surface plate. However, this is only valid for single-color flatbed presses. That is, when printing one color at a time, the plate mounting position does not matter, and the register can be adjusted at the position where the paper is placed, so that the registration operation can be performed with such a device.

機に関しては、自動見当合わせ装置自体が存在しない。However, with regard to the flatbed printing machine for performing continuous multicolor printing of two or more colors, there is a drawback that the above-mentioned apparatus cannot perform the registration operation. That is, there is no automatic registration device itself for a multi-color flatbed printing machine of two-color printing or more.

Experience must grasp the relationship between the amount of displacement of the visual register and the amount of movement of the plate mounting position, which requires skill. Therefore, the load on the operator is also great, and automation is desired for labor saving and labor saving of skill and standardization of proof printing.

る。FIG. 2 shows a conceptual diagram of an embodiment of the registration apparatus according to the present invention. The printed matter 17 is placed on the table 21 of the apparatus with the attestation 21. The registration device is provided with two rails, a horizontal rail 11 and a vertical rail 13, so that the camera 15 can be moved directly above a registration mark 19 on the printed matter 17. The register 15 of the printed matter 17 is read by the camera 15, and the reference color switch 23 first selects which color is used as a reference.

見当標がしっかり印刷されており、見当標の周囲に汚れ
の無い印刷物が得られれば良い。The registering operation when this embodiment is applied to a flatbed offset four-color proof press will be described. First, a printing plate is attached to the proof press and several sheets are printed. What is important here is to return the position of the plate holding device of each plate to the position of the origin before mounting the plate. The number of sheets to be printed varies depending on the printing conditions, but it is sufficient that the registration mark of each color is printed firmly and a printed material without stains around the registration mark can be obtained.

真上に移動させ、印刷物１７の見当標１９を読みとる。This printed matter is placed on a registration device having a structure as shown in FIG. At this time, it is important to place the edge of the printed matter firmly on the ate 21. This is because the reference origin is constantly in the same position. The two rails, the horizontal rail 11 and the vertical rail 13, provided in the registration device move the camera 15 directly above the register 19 of the printed matter 17 to read the register 19 of the printed matter 17.

が、作業性や精度の面から３箇所程度が好ましい。Here, as the register to be taken in, a cross-shaped one such as the register 19 of (FIG. 2) is desirable because it is easy to understand the amount of deviation in the vertical and horizontal directions, but the type is appropriately selected according to the printed matter. The good thing is clear. Further, the number of registration marks to be taken in by the camera is arbitrary, but it is preferable to be about three in terms of workability and accuracy.

レ量を表示する。From the image captured by the camera 15, a reference color plate is first selected. It goes without saying that the standard color plate is preferably a color that can be easily captured by the camera. Here, the sample is a printed matter using four colors of ink, indigo, red, and yellow, and the color of the black ink is used as the reference, but the same applies when other colors are used as the reference. Since the black color is used as a reference, the black reference color switch 23 is pressed. Then, in the apparatus, the misregistration amount of the printing plate position of each of the other colors is calculated with reference to the register position of the black color, and the misregistration amount display monitor 25 displays the misregistration amount.

な理由を、以下に説明する。Here, in order to calculate the amount of deviation, calculation is performed by adding the data of the amount and type of non-printed material and the data of the pattern area of each plate to be printed. The reason for this data is explained below.

を予めインプットした個々のチャンネルを持つことが好
ましい。The features of the flatbed offset proof printing machine are:
Due to the non-printed matter being fixed by the paper gripping device during printing, there are the following phenomena regarding the registration. That is,
During the transfer from the blanket to the paper, due to the friction between the paper and the blanket, the fixed position of the paper gradually moves in the printing direction after the second color printing. The amount of movement varies depending on the weight and type of paper, the pattern area of printing, and the like. Therefore,
It is preferable to have individual channels pre-input with these data in order to determine the normal position where the printing plate should be placed in consideration of the movement amount of the non-printed material due to various causes.

容範囲内になれば、自動的に駆動装置は止まる。After the displacement amount is displayed, the automatic registration switch 29 is pressed, and a signal is sent to the printing machine to move the printing plates of each color except black ink according to the displacement amount while pressing and holding. On the basis of the adjustment data sent, the plate gripper moves independently in the X-axis direction and the Y-axis direction in order to correct the printing plate to the normal position for each plate. When the deviation amount of each color is 0 or within the allowable range, the drive device automatically stops.
【００２３】このように、見当を合わす為のノウハウが
データとして含まれているから、非印刷物による違い等
の経験則がなくても、見当合わせ作業を簡単に行う事が
出来る。In this way, since the know-how for registering is included as data, the registering work can be easily performed without any empirical rule such as a difference due to non-printed matter.

労力軽減につながり、校正刷りの標準化にもつながる。The fact that this skill is a shared property allows even a beginner operator to perform registration work easily and accurately like a skilled person, which leads to labor saving and labor saving of skill, and proof printing. It also leads to standardization.

が確認できた。The registration time by this apparatus was about 2 minutes including the time for placing the sample printed matter. Since the registration work is a work that requires skill, there is a time lag between people, and the proof printing work involves adjusting the water content and performing other work such as ink supply at the same time. I can't get the exact time. However, it has been confirmed that by using this device, it is possible to obtain a printed matter with proper registration in a short time without depending on the skill and intuition of the operator.

For example, in the embodiment, the flatbed offset four-color proof printing machine is used as an example, but a flatbed offset two-color proof printing machine can be used.
Even with a flatbed offset single-color proof press, you can fix the paper placement position of the paper by reading the registration target of the printing of a certain standard color and adjusting the position of the printing plate based on that data. You can register without registration.

わさず、見当合わせ作業の完全自動化が可能となる。It is also conceivable to install a camera for reading the registration mark of the printed matter on the flatbed printing machine. In this case,
Since it is possible to omit the work of extracting the printed matter and placing it on the apparatus, if the reference printing plate is determined in advance, the registering work can be completely automated without any human intervention.
