【産業上の利用分野】本発明は、印刷物や成形品等の色
彩や光沢を、光電変換手段を使用して高精度に測定する
色彩・光沢度測定装置に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color / glossiness measuring device for highly accurately measuring the color and gloss of printed matter, molded products, etc. using photoelectric conversion means.
【０００２】[0002]
【従来の技術】印刷や物体の色、艶を客観的かつ高精度
に測定し評価するには、色彩と光沢感とは切り放せず、
人間の受ける感じや、仕上がりの優劣に大きく影響する
要因となっている。しかし、この管理のためには、高精
度な測色計や光沢計が必要である。2. Description of the Related Art In order to objectively and highly accurately measure and evaluate the color and luster of printing and objects, it is necessary to separate color and luster from each other.
It is a factor that greatly affects the feeling that people receive and the quality of finished products. However, a highly accurate colorimeter and gloss meter are required for this management.
【０００３】ところが一般には、印刷やコピー方式、物
体の基材や製造方法等の違いにより、表面の細かい凹凸
の大小の違いにより表面の光沢感は様々となるため、高
精度な色彩測定や光沢測定には困難を伴う。However, in general, the glossiness of the surface varies depending on the size of the fine irregularities on the surface due to the difference in the printing or copying method, the base material of the object, the manufacturing method, etc. Therefore, highly accurate color measurement and gloss Measurement is difficult.

内部を通過又は表面で吸収により着色されて反射した光
束は、物体の色味を持った拡散光となって視認される。As shown in FIGS. 2 (a) to 2 (c), the reflected light beam on the object surface has various modes such as direction and reflectance. Then, this reflected light becomes specular reflected light of the same color as the illumination light source, and is visually recognized as gloss of a printed matter or an object. On the other hand, the light flux that passes through the inside of the object or is colored by absorption on the surface and is reflected is visually recognized as diffused light having the tint of the object.

により大きく変るので、色彩測定値、光沢度の測定値は
測定器により変るのが普通である。At this time, the color of the object and the gloss, that is, the specular reflected light flux are visually recognized separately, but the same points are evaluated and judged as one. On the other hand, the color of the object and the intensity of the specularly reflected light flux in the measuring device greatly change depending on the arrangement state of the illumination light and the observation system, so the color measurement value and the glossiness measurement value usually change depending on the measuring device. .

Here, the 45 degree illumination / vertical light receiving method, that is, the 45-0 method is defined as one of the measuring methods that reduces the influence of specular reflection.
