JPS581153A - 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 straight lines extending radially from the center of the circle or polygon and thrusting through the circle or polygon, and has at least one of said straight lines as an arrow-shaped part is used, and solid printing in respective colors is provided at prescribed positions of this printing estimation mark to perform estimation. For example, three printing colors are used in the figure and three colors 13, 15 and 17 are printed firstly; and the printing color 13 shifts from the printing estimation mark in the reference color 17 as shown by an arrow A in the figure, and the printing color 15 shifts as shown by an arrow B in the figure. For this purpose, the printing color 13 to be estimated is shifted as shown by the arrow A and the printing color 15 is also shifted as shown by an arrow B, thus correcting the extents of shifting of the reference color 17 from the respective colors.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to printed registration marks and registration methods that facilitate registration.

In general, in multicolor printing, a cross-shaped registration mark l as shown in Figure 1 is used, and in the case of form printing, printing consists of a rectangle and a cross surrounding a marginal punch hole 3 as shown in Figure 2. A registration mark is 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 registering 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 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 for a multicolor map and a 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 is a printing method consisting of a circle or polygon and a plurality of straight lines passing through the center of the circle or polygon, extending radially, and penetrating the circle or polygon, at least one of the straight lines having an arrow. This method is characterized by using a registration mark and printing a solid color of each color at a predetermined position of the printed registration mark to achieve registration.

The present invention will be explained below based on illustrated embodiments.

In this embodiment, the number of printing colors is six, and FIG. 3 shows the shape of the printed registration mark for a multicolor map according to the present invention.

The printed registration mark of this embodiment consists of a circle and a straight line 9, and seven of the straight lines are provided with arrows //.

The black areas in FIGS. 9 and 9 indicate the printing areas of each color. Figure 9 shows the colors used as a reference when registering, and shows the outline of the printed registration mark of the present invention as a solid line, and furthermore, the area in which the mark is equally divided into six printing colors is shown as a solid line. . The printing register is adjusted by aligning each color shown in FIGS. S to 9 with the predetermined position of the printing registration mark printed in this reference color.

Furthermore, when using the printed registration mark of the present invention on a map, by matching the direction indicated by the arrow of the printed registration mark with the north direction of the map, the north direction can be displayed using the arrow of the printed registration mark. can.

Furthermore, when the printing registration mark is used for general printed matter, the printing direction, etc. can be indicated by an arrow.

Note that the shape of the printed registration mark is not limited to the above embodiment, but may be a combination of polygons and straight lines, and the number of straight lines may be changed depending on the number of printing colors. Figures 70 to 16 show other embodiments of the printed registration mark, and Figures 1O to 1U
In the figures, the number of straight lines is changed according to the number of printing colors from three to S, and Figures 73 to 1 O are combinations of polygons and straight lines. Furthermore, the number of arrows is not limited to one, and there may be more than one.

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

The printed registration mark should have the same shape as the printed registration mark shown in Fig. 3 (・The case where the number of printing colors is 3 will be explained. Fig. 17 shows the first three colors 13,
It shows the state in which lS, /7 is printed, and the reference color /')
Printing color /3 is shifted in the direction of the arrow in the figure, while printing color 15 is shifted in the direction of arrow B in the figure with respect to the printed registration mark. Therefore, in order to adjust the printing register, printing color 13 is shifted in the direction of arrow A', printing color /S is shifted in the direction of arrow "," and the amount of deviation between the reference color /7 and each color is corrected.

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

(11) 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 also possible to inspect for color omission (colors that should be printed are not printed). can.

(2) Since each color is printed in a flat area, the density can be managed using the solid area. Therefore, there is no need to use colored soil.

(3) The arrow of the printing registration mark has the function of indicating the north direction of the map, so it can be printed inside the product, and therefore it can be used to cut bulky parts of paper, which was previously a dream. When can you skip the steps?
