Why is a Color Evaluation Box important?

YR053445-YR053447-6-1.png
The importance of a Color Evaluation Box, to evaluate and display the appearance of products as well as, identify notable inconsistencies between the color of a sample and the standard color, in order to order human visual perception, with numerical color values. Typically, in production environments, early completion of these color assessments helps to minimize duplication of work and future additional costs. For each sensory evaluation, the samples to be assessed should be established, if necessary, prepared and presented in the same way, every time.
Similarly, the Color Evaluation Box can be applied to industries that need to perform color difference tests, as follows, as the leading designer and manufacturer of color matching instrument products for the graphic arts, photography, textile, dyeing, packaging, printing, leather, inks, knitwear, plastics, automotive and ceramics industries.

Importance of perception in a color evaluation box

Basically, color is appreciated under the sensitivity of the human eye, and this varies from person to person, which often results in color appearing different in each individual, and even, perception can affect how the color of the sample is perceived. In this way, the way you appreciate it can affect the appearance of your color. Because seeing an object from a slightly different angle, for example, can make the object lighter or darker. For this reason, sample viewing angle and other visual conditions must be consistent in every evaluation. It is therefore recommended that : 

  • Do not place other objects in the evaluation area, which will break with the appearance of color.
  • Place samples flat inside the box or at a 45° angle, changing position from left to right and top to bottom, to observe any color changes.
  • Hold samples in parallel to identify color differences.

Color evaluation box configurations

In the mechanisms of an evaluation box, it facilitates the importance of color, as it is one of the most important characteristics of an object, and the evaluation of it must be appropriate and accurate in the samples. The box configuration is very important, as it allows two or three illuminants to be formed, which are suggested for metamerism evaluation, being these D65 (daylight), F2 (fluorescent light) and, A (incandescent light).
As a result, images illuminated by D65 radiate more energy in the blue region, in the case of illuminant F2 (cool white light), radiate more energy in the yellow region and finally illuminant A (incandescent), radiates more energy in the red region. If you’re doing a raw material application and you’re only looking to evaluate color, without taking into account the effect of appearance, then you need to configure the box as a specular mechanism to measure color, without taking into account the appearance of its finish.
