Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は光源の演色性検査に使用される演色性検査カー
ドに関する。The present invention relates to a color rendering test card used for color rendering test of a light source.
〔従来の技術〕 一般に物体の色は照明の質によつて変つて見えるため、
カラー印刷物の色の仕上りは一定の照明光の下で印刷原
稿であるリバーサルカラーフイルムと校正刷あるいは印
刷仕上り品を比較して検討するわけであるが、印刷物の
方は上から照明光を当てて、反射光の状態を見、リバー
サルカラーフイルムはカラービュアライトボツクスの上
に置いて透過光の状態で見ることになる。[Prior Art] In general, the color of an object appears to change depending on the quality of lighting.
The color finish of color prints is examined by comparing the reversal color film, which is the printing original, with a proof print or print finished product under a constant illumination light. , See the state of the reflected light, put the reversal color film on the color viewer light box and see the state of the transmitted light.
そのために同時に２種の（反射光と透過光）の標準的な
照明が必要になるとともに、その２種は共通な光質を持
たなければならない。Therefore, two types of standard illumination (reflected light and transmitted light) are required at the same time, and the two types must have a common light quality.
印刷物の色の評価は、日本印刷学会が推薦している色温
度5000゜Kに±200゜Kの光源の下に行われるのが通例で
あり、実用的にはJIS−Z8726「光源の演色性評価方法」
による平均演出評価指数が98前後の螢光灯が標準的な光
源として用いられている。欧米各国においても状況は類
似している。It is customary to evaluate the color of printed matter under a light source of ± 200 ° K at a color temperature of 5000 ° K recommended by the Japan Printing Association, and practically JIS-Z8726 “Color rendering of light source”. Evaluation methods"
Fluorescent lamps with an average performance evaluation index of about 98 are used as standard light sources. The situation is similar in Western countries.
その際、透過用と反射用の２種の光源の光質は共通して
いなければならなく、特に基準となるリバーサルカラー
フイルムを見るためのカラービユアライトボツクスはデ
ザイナーなどの発注者が用いているものと受注者である
印刷会社が用いているものとが共通の光質をもつている
必要がある。また、メイクアツプの化粧品には口紅、ほ
お紅およびアイシヤドウ等様々なものがあるが、その化
粧品の色或いは化粧した肌の色は照明の光の質によつて
様々に変つて見える性質をもつている。At that time, the light qualities of the two light sources for transmission and reflection must be common, and the color viewer light box for seeing the standard reversal color film is used by the orderer such as a designer. There is a common light quality between the printer and the printer used by the contractor. There are various types of makeup cosmetics such as lipstick, blusher, and Aishado, and the color of the makeup or the color of the skin to which makeup is applied has the property of appearing variously changed depending on the quality of the light of illumination.
従つて同じ化粧品を用いて化粧を施しても照明条件によ
つて化粧した唇の色や顔の色が相当違つて見える場合が
ある。Therefore, even if makeup is applied using the same cosmetics, the color of the lips and the face of the makeup may be considerably different depending on the lighting conditions.
そのため、いつも変らない色調のメイクアツプを施こす
ようにするには照明条件が前にメイクアツプしたときと
同じであるが、或いは照明条件が正しいかどうかが重要
な要件となつている。Therefore, in order to apply a make-up having a color tone that does not always change, the lighting condition is the same as that before the make-up, or whether or not the lighting condition is correct is an important requirement.
物体の表面色を正しく判断するときの照明に用いる光源
に日本工業規格（JIS−Z8723）に規定されている例えば
直射日光をさけた自然光（日の出３時間後から日没３時
間前までの北窓の光）がある。しかしながら数多く存在
する照明条件が適正であるかどうかメイクアツプする人
にとつて、なかなか判断できないという問題点があつ
た。The light source used for lighting to correctly determine the surface color of an object is specified by Japanese Industrial Standards (JIS-Z8723), for example, natural light that avoids direct sunlight (from the north window from 3 hours after sunrise to 3 hours before sunset) Light). However, there is a problem that it is difficult for a person who makes a makeup to judge whether or not there are many lighting conditions.
本発明はかかる問題点を解決することを目的としてなし
たもので、標準光源の下および自然昼光の下ででは同一
となり、そうでないときは色の差が生じるように調色し
た光源の演色性検査カードを提供するものである。The present invention has been made for the purpose of solving such a problem, and it is the color rendering of a light source that is toned under the standard light source and under the natural daylight, and if not, a color difference is generated. It provides a sex test card.
本発明を図面について説明する。第１図においてA,B,C

てもよい。着色シートA,B,Cの色素は次のようである。The present invention will be described with reference to the drawings. In Figure 1, A, B, C
Is a coloring sheet, and the coloring sheets A, B, and C are those obtained by kneading a pigment into a plastic such as polyvinyl chloride, polystyrene, polyethylene, vinyl chloride-vinyl acetate on the mount 2 of the color rendering test card 1 of the light source, or A plastic coated with a pigment may be used, or the base 2 may be coated directly. The dyes of the coloring sheets A, B and C are as follows.
着色シートＡは 二酸化チタンホワイト（ルチル型） チタンイエロー顔料 コルトブルー顔料 カドミウムレツド顔料 着色シートＢは 二酸化チタンホワイト（アナターゼ型） ジスアゾイエロー顔料 銅フタロシアニンブルー顔料 ローダミンレーキ顔料 着色シートＣは 二酸化チタンホワイト（ルチル型） クロムイエロー顔料 ウルトラマリンブルー顔料 溶性アゾ系レツド顔料 である。Coloring sheet A is titanium dioxide white (rutile type) Titanium yellow pigment Colt blue pigment Cadmium red pigment Coloring sheet B is titanium dioxide white (anatase type) Disazo yellow pigment Copper phthalocyanine blue pigment Rhodamine lake pigment Coloring sheet C is titanium dioxide white ( Rutile type) Chrome yellow pigment Ultramarine blue pigment Soluble azo red pigment.
上記着色シートA,B,CはＡとＢの色票が近似して見える
光源の状態は、色温度5000゜Kに近く、印刷物の色評価
に適した条件であり、ＢとＣの色票の色が近似して見え

るいは直射日光を避けた自然光の条件と類似しており、
一般的な色評価に適した条件である。In the above coloring sheets A, B, and C, the light source state in which the color charts of A and B appear similar to each other is close to a color temperature of 5000 ° K, which is a condition suitable for color evaluation of printed matter. The state of the light source where the colors of the colors appear to be similar is close to the color temperature of 6500 ° K and is similar to the condition of synthetic daylight D 65 or natural light avoiding direct sunlight.
The conditions are suitable for general color evaluation.
例えば第２図，第３図に示すように、印刷物の場合Ａと
Ｂが同じであつてＣが異なつていれば、光源はそのまま
使用してもよいものであり、その照明が標準光源に近い
状態を示す。また、ＢとＣが同じであつてＡが異なつて
いれば、光源は一般的なものに使用してよい。即ちその
照明がJIS−Z8723に規定されている標準光Ｃ或はこれに
準じたものである。For example, as shown in FIG. 2 and FIG. 3, in the case of printed matter, if A and B are the same and C is different, the light source may be used as it is, and its illumination is the standard light source. Indicates a close condition. If B and C are the same and A is different, the light source may be a general light source. That is, the illumination is the standard light C specified in JIS-Z8723 or a light in conformity therewith.
但しA,B,Cの３つの着色シートが完全に一致して見える
ものではない。However, the three colored sheets A, B, and C do not look exactly the same.
