The color evaluation cabinet is a tool that allows simulating from different light principles the objective evaluation of shades at any time and from any perspective. The cabinets are equipped with 5 light sources, which have the consistency of light sources and provide excellent viewing scenarios, to take reliable critical color measurements under constant lighting.
The color evaluation cabinet, is applicable for industries that require testing color difference, and provides users with the ideal color combination, whether for graphic arts, photography, textile, dyeing, packaging, printing, leather industries, inks, knitted genres, plastic, automotive and ceramics.
Techniques for Color Evaluation in a Light Box
For the study of colors, through the use of evaluation cabinets, standardized techniques are used to make the process reliable, where the participation of light, the observer and the object to evaluate, become fundamental pillars in its development. In this sense, the light source, is important for the study, as it determines the luminescence, among them are: D65 Day Light, TL84, Cool White Fluorescent CWF, Incandescent A light, etc.
In this way, the user can control the tool based on the elements provided by the light boxes, to understand the physical presentation of the object to study, ensuring the consistency and objectivity, preventing it from being affected by changes in natural or artificial lighting.
In this sense, through the proper handling of light, increases in the efficiency and productivity of the evaluation cabinets can be achieved, to stimulate visual attraction to certain objects or spaces.
Influence of Colors on the Light Box
The illuminance or amount of luminous energy through the light boxes, for the human eye, influences the distribution of energy in the different wavelengths of the spectrum, to have a good color reproduction, the light has to have enough energy in all of them.
For this reason, the color evaluation box provides uniform, standardized viewing environments to evaluate color variations and discover lighting sources.
For the effectiveness of light boxes, it is necessary to have differences in color, illumination, light and shade, etc. to be able to perceive any object. It is therefore recommended that:
- The environment should have an adequate level of lighting.
- Apply a single type and mark of luminaire (spotlights or fluorescents) to prevent differentiation of the color of the light source.
- Do not exceed the use of the evaluation box, because it may cause variations in hue and hue.
- Store samples and color charts appropriately.
In summary, the higher the contrast, the greater the differentiation between objects, however, the excessive contrast in one space can cause glare, due to the large difference in illumination between the light source and the surrounding space.
