Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing register mark used for color registration of multicolor printed matter, and is capable of identifying the register misregistration of each color printing plate during or after printing, and identifying the amount and direction of the misregistration. The purpose is to make decisions quickly and correctly.

Conventionally, cross-shaped, concentric, and other registration marks have been used as print registration marks for multicolor printing, but the registration marks of each color overlap, making it difficult to accurately determine the state of misregistration, or Even if the printing register mark is printed at the correct position, it is difficult to accurately determine which color is out of register, in which direction, and by how much.

Taking these points into consideration, the present invention is a printing registration mark that allows accurate printing status of each color registration and identification. In the mark, a reference blank mark divided into multiple blanks corresponding to the number of colors that require printing registration from the second color is printed in the first color, and the same as the outer peripheral edge or inner peripheral edge of the blank mark. This printing register mark is characterized in that each color register mark having a shape and size is printed sequentially from the second color on each blank of the reference blank mark in accordance with the register.

If the present invention is explained in detail according to the drawings, the first
The figure shows a reference blank mark 1 to be printed in the first color, and consists of a plurality of blanks 1-2, 1-3, 1-4, etc. corresponding to the number of colors to be printed from the second color. This reference blank mark 1 is formed at a predetermined position on the first color printing plate. Next, blank mark 1
Color register marks 2, 3, 4, etc. having the same shape and size as the outer peripheral edge or inner peripheral edge of are formed at predetermined positions on the printing plate of the second color, the third color, and the fourth color, respectively. , color register mark 2 and blank 1-3 for blank 1-2 of blank mark 1.
A color register mark 3 is printed for the blank 1-4, and a color register mark 4 is printed for the blank 1-4 so as to match the peripheral edge of each blank, thereby performing registration. Number of blanks for blank mark 1 and color register mark 2,
The numbers of 3, 4, and so on are the same and are determined according to the number of colors to be printed.For example, the number of blanks for 4-color printing is 3, and for 5-color printing, it is 4, but for solid printing etc. Color registration marks and blanks for color printing that do not require registration can be excluded.

The arrangement of the printing register marks of the present invention with respect to the picture area 5 is as shown in FIG. The color register marks 2, 3, 4, .

In the printing of the printing register mark of the present invention, in the first color printing, the reference blank mark 1 is printed, and in the second color printing, the color register mark 2 is printed so as to match the peripheral edge of the blank 1-2. Then, in the third color printing, a color register mark 3 is printed so as to match the peripheral edge of the blank 1-3, and in the fourth color printing, a color register mark 4 is printed on the peripheral edge of the blank 1-4. Print and register so that they match. This registration operation is performed in the printing direction and in the printing width direction. Registration in the printing direction can be performed with the horizontal row registration mark 1-Y, and registration in the printing width direction can be performed with the column registration mark 1-X. However, if the position of the printing color to be registered with the reference blank mark 1 is determined in advance in the plate-making process, registration can be achieved using only 1-X or 1-Y. In this way, each color registration mark 2, 3, 4, ...... is matched with the reference blank mark 1 of each blank mark 1-X, 1-Y as shown in Fig. 2, and good registration is achieved. Get status.

According to the present invention, since each color registration mark is separately displayed in a single color, it is possible to quickly identify which color is out of register and by how much, as shown in FIG. Even in this case, the registration state of printing colors can be clearly determined. Furthermore, the feature of the present invention is that with respect to the blank mark 1 which is the reference registration mark,
Since it is possible to clearly identify which color registration mark is misaligned in which direction, it is possible to accurately identify the direction and amount of correction necessary for register correction by operating the printing machine, and to make corrections. It is also possible to check the correct status.

The present invention is a printing register mark in which each color register mark of the same shape and size is registered in a single color in vertical or horizontal rows with respect to a reference register mark, and is useful for identifying each color register in multicolor printing. Corrections can be made quickly and accurately, and are extremely effective in improving the efficiency of operations such as printing registration and register checking, and in improving the quality of printed matter.
