Description

[Detailed Description of the Invention] The present invention relates to a color chart selector that can facilitate the selection of a color chart used to determine the color tone when producing color printed matter.

In order to produce color printed matter, it is necessary to replace the continuous tones of the original with the tones of color-separated halftone dots of the printed matter, and at this time, a color chart is used to make the finish of the printed matter the same as the tones of the original. However, the ink set most suitable for the original is selected.

However, color chart a, for example,
As shown in the figure, the basic combination is two colors 1 and 2, each square 3 is arranged in a grid pattern, and the upper and right sides have numbers 4 and 4' indicating the halftone dots of that row.
are arranged in units of 10 from 0 to 100%, indicating that one color 1 is printed in the horizontal direction and the other color 2 is printed in the vertical direction with 11 gradations. Since the grids 3 are close to each other, when looking at the three tones of one grid,
The colors of the other squares 3 around it were mixed, making it difficult to contrast with the color tone of the original, and it was sometimes possible to misread the color tone values 4 written on the top and right sides.

In addition, at the top of the color chart a, the basic 2
Colors 1 and 2 are shown. Depending on the case, other colors 5 and 6 and their numerical values 7 and 7' may also be shown next to them.

The present invention was devised in view of the above-mentioned conventional problems, and it is possible to easily select a color tone that matches the color tone of the document from among a plurality of squares in a color chart, and to It is an object of the present invention to provide a color chart selector that prevents the user from misreading the numerical values of two-color halftone dots printed on the eyes.

Therefore, in the present invention, the color chart selector is formed by forming a window corresponding to one square of the color chart near one corner of a transparent thin plate made of a resin material, and forming a window corresponding to one square of the color chart around the window. A wide opaque window frame is formed that covers the surrounding squares, and the numbers of the two-color halftone dots printed on the squares that the window portion is in contact with can be seen. , a ruled line is provided from the center of the two inner sides of the thin plate of the window frame, parallel to the edges of the two sides of the thin plate, respectively, overlapping the numbers of the halftone dots written on the top and right sides of the color chart, and The intended purpose is achieved by providing a structure in which the ruled lines are provided with small windows surrounding the numerical values of the halftone dots at predetermined intervals.

The present invention will be described below with reference to illustrative embodiments.

b is a color chart selector, which is a thin plate 1 formed of a transparent resin material and having a substantially rectangular shape;
1, and a window 12 corresponding to one grid 3 of the color chart a is formed near one corner of the thin plate 11. Around the window 12, there is a wide white opaque window frame 1 that covers eight squares 3 adjacent to the square 3.
3 is formed. In the window frame 13, from the center of the two sides 13a and 13b which are inside the thin plate 11, and parallel to the edges 11a and 11b of the two sides of the thin plate 11, are written on the upper and right sides of the color chart a. The ruled line 14, which overlaps the halftone dot numbers 4 and 4',
15, and each of the ruled lines 14 and 15 has a predetermined interval, that is, the same interval as the interval between the squares 3, and a plurality of ruled lines 14 and 15 are arranged so as to surround the numerical values 4 and 4' of the halftone dots. Small windows 16 and 17 are provided.

To select the color tone to be printed using the color chart selector b, first select color chart a from the color chart in which the two basic colors used in the document to be printed are printed, and then The color chart selector b is placed on the chart a and moved appropriately to select one square 3 from the color chart a. At this time, the color tone of the squares 3 appearing on the window 12 can be clearly seen because the surrounding squares 3 are covered by the window frame 13. Next, ruled line 1
The numbers 4 and 4' of the halftone dots located in the small windows 16 and 17 above 4 and 15 are read and the halftone dots of one color 1 are determined.
Check the values 4 and 4' of the halftone dots of the other color 2.

As described above, the present invention forms a window corresponding to one square of a color chart near one corner of a transparent thin plate made of a resin material, and surrounds the window adjacent to one square. Since a wide opaque window frame is formed to cover the squares, it is possible to easily select a predetermined color tone without being confused by the color tone of the surrounding squares.

Furthermore, according to the present invention, when a predetermined color tone is selected, the numerical values of the halftone dots of the two colors appearing in that square are read by the ruled lines having small windows.
You can check the numbers accurately.
