電的に行なうのＫは不便である。Power 2 - In the case of printing, it is often said that specifying colors is abstract and difficult to understand. In other words, while the orderer grasps, judges, and evaluates colors intuitively, in actual printing, colors are basically expressed by a mixture of the three primary colors cyan, magenta, and yellow.
A very physical reproduction method is used to control the amount of mixing, controlling the size of the halftone area ratio, and a medium that converts the sensory quantity expressed by the orderer into a physical quantity (halftone area ratio) for printing reproduction. With the plate making and printing power chart currently available as a color translation means, it is inconvenient to communicate concretely and electrically between the orderer and the order recipient at the time of submission and proofreading. .
色には、色相、明度および彩度の３つの属性があるが、
印刷時においてこの３つの属性を独立して調整すること
は困難である。Color has three attributes: hue, brightness, and saturation.
It is difficult to adjust these three attributes independently during printing.
％に、明度と彩度とは、感覚的にもあまシ明確に区別さ

果として知覚されることが多い。%, brightness and saturation are not clearly distinguished perceptually, and are often perceived simply as a tone of one color as a synergistic effect of brightness and saturation.
本発明は、色相、明度および彩度を３次元にとらえた色

という効果を奏する。The present invention is based on the idea of a color solid that captures hue, brightness, and saturation in three dimensions, and provides a color chart for plate making and printing that shows how the brightness and saturation change for each hue. This has the effect of making it possible to accurately and easily communicate color specifications and proofreading between the person ordering plate-making printing and the person receiving the order.

One or two of the three primary colors magenta, cyan, and yellow, each of which has a maximum halftone dot area ratio of 100%, is applied to the circumferential portion of the joint surface of a three-dimensional solid in the shape of two cones joined at their bases. Mark the required number of hue points consisting of a combination of species, and mark each hue point, the upper vertex (achromatic white; the halftone dot area ratio of the three primary colors is 0%), and the lower vertex (achromatic black; the halftone dot area ratio of the three primary colors). The halftone dot area ratio is 100%), and the upper hypotenuse connecting each hue point and the upper vertex has 1 part that participates in the hue formation of the hue point.
Equal dividing points are provided toward the upper vertex to reduce the halftone dot area ratio of the seed or two primary colors to 0%, and hue formation of the hue point is provided on the lower oblique side connecting each hue point and the lower vertex. 10 to
Equal dividing points are provided toward all the lower vertices to increase the halftone dot area ratio of primary colors of 0% or 2 rice that are not completely involved up to 0%, and on these upper and lower hypotenuses. A color having three deep color halftone area ratios divided by a combination of equally divided points is displayed in each division, and the brightness is indicated in the vertical axis direction of the triangle, and the saturation is indicated in the horizontal axis direction of the triangle. K is used to show each.

In this way, each hue point graduated on the circumference of the color solid, for example M (magenta) and the upper apex W (achromatic white, the halftone area ratio of the three colors are all 0%) and the lower A triangular cross section 2 is formed connecting the vertex Bk (achromatic black, the halftone dot area ratio of all three primary colors is 100%).Then, the upper hypotenuse 3 connecting the hue point M of this triangle and the upper vertex W is formed. An equal dividing point is provided toward the upper vertex W to reduce the magenta halftone dot area ratio involved in the hue formation of the hue point by dividing it into 10 equal parts from 100% to 0%.
In addition, on the lower hypotenuse number connecting the hue point M and the lower vertex Bk, the halftone dot area ratio of cyan and yellow, which are not involved in the hue formation of the hue point, is divided into 10 equal parts and increased from 0% to 100%. Points are provided toward the lower vertex Bk, and colors having three primary color halftone area ratios provided on the upper and lower oblique sides and partitioned by a combination K of equally divided points of 10 are displayed in each section. The details of this are shown in Figure 2, where the halftone area ratios of the three primary colors are indicated by numbers up to t for magenta, numbers with ()t- for cyan, and numbers in brackets for yellow. Each is indicated by the number attached.

・、れの詳細は第３図に示され、３原色の網点面積率の
表示方法は第２図の場合と同様である。An equal dividing point is provided toward the upper vertex wK, and the halftone dot area ratio of magenta, which is not involved in hue formation at the hue point, is set from 0% to 100% on the lower hypotenuse, and from 0% to 100%, and 6
Yellow halftone dot area ratio t-0%, which only contributes 0%
Colors having three primary color halftone area ratios divided by a combination of 10 equal dividing points from 40% to 40% are provided toward the lower vertex BkK, and these 10 equal dividing points are provided on the upper and lower oblique sides. is displayed in each section. Details of these are shown in FIG. 3, and the method of displaying the dot area ratios of the three primary colors is the same as in FIG. 2.
従って、これらの各三角形において、上部頂点Ｗと下部

せばよいととＫなる。Therefore, in each of these triangles, the direction of the vertical axis 8 connecting the upper apex W and the lower apex Bk represents brightness, and the direction of the center line of this vertical axis, the horizontal axis 9.9, represents saturation. For example, the colors displayed in section 10 in Figure 5 [halftone area ratio (sum of halftone area ratios shown on the upper hypotenuse and lower hypotenuse): magenta 60%, cyan 80%, yellow 68%] and lightness. If you want a color with a large chroma, look for a color that is higher in the vertical axis direction, and if you want a color with a higher saturation, look for a color that is farther away in the horizontal direction from the vertical axis. It's okay and K.

It is even more convenient to search for brightness and saturation if it is displayed as (brightness/saturation).

- You can judge at a glance by looking at the color how much you should increase or decrease the halftone area ratio.
This means that there will be sufficient communication between the two parties in printing.

You can clearly know the limits of color reproduction in printing by comparing with , and it can also be conveniently used to distinguish between colors that are easy to reproduce in 9-printing and colors that are difficult to reproduce. Note that the force 2 shown by the triangle - the vertical axis part of the chart - appears between each hue point, so that part is used as a common part together with the hue color chart in the complementary color Kanyu as a rectangular envoy. I can do it with you too.
