JPS581154A - Mark and method for estimating printing for multicolor map - Google Patents

Abstract

PURPOSE:To easily observe the extent of shifting from a reference position without any hindrance of dark color with reference to even light color, and to perform density control by using a solid printing part without inspection of decoloration and use of a color ball. CONSTITUTION:A printing estimation mark which consists of a circle or polygon and plural straihgt lines extending radially from the center of the circle or polygon and thrusting through the circle or polygon is used and solid printing parts in respective colors are provided at prescribed positions of this mark to perform estimation. In this figure, the number of printing colors in use are three and three colors 11, 13 and 15 are printed firstly; the printing color 11 shifts from the mark in the reference color 15 as shown by an arrow A in the figure, and the printing color 13, on the other hand, shifts as shown by an arrow B. For this purpose, the printing color 11 to be estimated is shifted as shown by the arrow A and the printing color 13 is shifted as shown by the arrow B, thus correcting the extents of shifting of respective colors from the reference color 15.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing registration mark and a registration method that facilitate the registration of each color in multicolor printing.

First, in multi-color printing, there is a cross-shaped stamp registration mark 1 as shown in Figure 111, and in the case of form printing, printing consists of a rectangle and a cross that surround a marginal bump size 5 as shown in 2nd WA. Registration marks 5v are provided for each color, and all printing registration marks are superimposed at the same position to match the printing registration of the pattern.

However, when registration is performed using these printed registration marks, each color is superimposed at exactly the same position, which has the disadvantage that light colors, such as yellow, are erased by other dark colors and are difficult to see.

Furthermore, since it is not possible to control the density of printed colors with conventional printed registration marks, colored clay must be used separately.

The present invention solves the above-mentioned drawbacks, and provides a printed registration mark and registration method that allows the amount of registration deviation of each color to be seen at a glance and allows easy registration.

That is, the present invention uses a printed registration mark consisting of a circle or polygon and a plurality of lines passing through the center of the core or polygon, extending to the radial direction, and passing through the center of the circle or polygon. This method is characterized by printing a solid pattern of each color at a predetermined position of the alignment mark to match the register.

'Hereinafter, the present invention will be explained based on the illustrated embodiments.

In this embodiment, the number of printing colors is six, and FIG. 3 shows the shape of the printed registration mark of the present invention.

The printed registration mark of this embodiment consists of a circle 7 and a straight line 119.

The black areas in Figures 4 to 9 indicate the printing areas of each color. Figure 114 shows the reference color when registering, and the outline of the printed registration mark of the present invention is made into a solid line, and the mark is equally divided into six printed colors, and the area is made into a peta. The printing register is adjusted by aligning each color shown in FIGS.

Note that the shape of the Honkawa IIi alignment mark is not limited to the above example, but can be formed by combining a polygon and 1-*)
The number of straight lines may be changed depending on the number of colors printed. 1110m to FIG. 16 show other embodiments of the printed register mark, and! 1110
The numbers of printing colors from S to 5 are printed according to the number of printing colors S to 5.
I! The number of lines is changed, and @13 figure to Ws16
The figure is a combination of a polygon and j[@.

Next, the registration method will be explained with reference to the drawings.

A case will be described in which the printing registration mark has the same shape as the printing registration mark shown in FIG. 5, and the number of printing colors is three. @17 Figure starts with 5 colors 11.1
! 1 and 15 are printed, and the printing color 11 is shifted in the direction of the arrow B in the figure with respect to the printing registration mark made by the reference color 15. On the other hand, the printing color 15 is shifted in the direction of the arrow B in the figure. direction. Therefore, in order to match the printing register, print color 11 is shifted in the direction of arrow M' and print color 13 is shifted in the direction of arrow B', and the amount of deviation between the reference color 15 and each color is corrected.

As described above, when the printed registration mark of the present invention is used, the following effects are produced.

(1) Since the printing position of each color is different, even if it is a light color, the amount of deviation from the reference position can be easily observed without being obstructed by dark colors, and it is possible to prevent missing colors (colors that should be printed are not printed) on the page. Tests can also be done.

0) Each color is printed solid, so use 70 peta copies.

concentration can be controlled. Therefore, there is no need to use colored soil.
