Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printed registration mark and a registration method for use in printing a multicolor map to facilitate printing registration of each color.

In general, in multicolor printing, a cross-shaped registration mark 1 as shown in Figure 1 is used, and in the case of form printing, printing is made up of a rectangle and a cross surrounding a marginal punch hole 3 as shown in Figure 2. Registration marks 5 are provided for each color, and by overlapping all the printing registration marks at the same position, the printing registration of the pattern is adjusted.

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, a separate colored ball must be used.

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 first invention of the present invention is a "registration mark for printing a multicolor map, in which when the registration marks corresponding to each color are superimposed, a position away from the center forms a circle or a polygon; A printed registration mark for a multicolor map, comprising a plurality of straight lines passing through the center of a polygon, extending radially, and penetrating the circle or polygon, one of the plurality of straight lines having an arrow. .”

Further, the second invention of the present invention is ``a registration method for printing a multicolor map, in which when registration marks corresponding to each color are superimposed, positions away from the center form a circle or a polygon; Pass through the center of the polygon,
The outline of the registration mark is made up of a plurality of straight lines extending radially and passing through the circle or polygon, one of which has an arrow, and the outline is printed in a printing color that serves as a reference for registration. This is a registration method characterized in that registration is achieved by printing a solid pattern of each color in accordance with a predetermined position of.

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 7 and a straight line 9, and one of the straight lines is provided with an arrow 11.

The black areas in FIGS. 4 to 9 indicate the printing areas of each color. Figure 4 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 the areas equally divided into six printing colors are shown as solid lines. .
The printing register is adjusted by aligning each color shown in FIGS. 5 to 9 with a 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 also 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 10 to 1
Figure 6 shows another example of the printed registration mark, and Figures 10 to 12 show the number of straight lines changed according to the number of printing colors from three to five. Figures 1 to 16 are a combination of polygons and straight lines. Further, the number of arrows is not limited to one, and there may be a plurality of arrows.

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

A case will be described in which the print registration mark has the same shape as the print registration mark shown in FIG. 3, and the number of printing colors is three. FIG. 17 shows the state in which three colors 13, 15, and 17 are first printed, and the printed color 13 is shifted in the direction of arrow A in the figure with respect to the printed registration mark made by the reference color 17, and on the other hand, Print color 15 is shifted in the direction of arrow B in the figure. Therefore, in order to adjust the printing register, print color 13 is shifted in the direction of arrow A' and print color 15 is moved.
is printed while being shifted in the direction of arrow B', and the amount of deviation between the reference color 17 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.

(1) Since the printing position for each color is different, it is possible to easily observe the amount of deviation from the reference position even if it is a light color without being obstructed by dark colors, and also inspect for color omission (colors that should be printed are not printed). You can also do it.

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

(3) Since the arrow of this printing registration mark has the function of indicating the north direction of the map, it can be printed inside the product, and the process of cutting unnecessary parts of the paper, which was previously done, has been eliminated. can be omitted.
