A colorimeter is a laboratory instrument that measures or specifies color by comparison with synthetic pigments. A typical colorimeter has a standard light source, three colored filters, photocells, and a standard reflective panel. More advanced colorimeters use photocells and electronic circuits as receivers instead of the human eye, thus speeding up the process. Obtaining results. The result of colorimeter detection is called chromaticity.
Factors that affect colorimeter measurement results are:
(1) Light source
The light source has a great influence on the color detection of the object, but using a specific color tube to illuminate the object, we will find that the original color of the material cannot be observed at all. This is why the industry now uses colorimeters to detect color.
(2) Light source illumination
The specific light-receiving surface is different, even when the same light is illuminated, the illuminance will be different, and the result is that the light and shade of the object are different. We use a colorimeter to measure one of the main reasons for the color difference in different periods of material brightness.
(3) far and near sight distance
When observing the color of matter, it is impossible to accurately observe the color of the object if it is too far or too close. Objects appear gray when too far away.
(4) Object size
Small objects are more affected by the color of the environment, that is, when we look at things, when two objects, one small and one large, are placed together, the larger one dominates. Large reflective surfaces will affect the color of small objects.
(5) Ambient color
When the colorimeter measures the change of the environment, it has a certain influence on the measurement of color difference. Objects are affected by neighboring objects in different environments, and the surface color changes. In particular, smooth-surfaced objects or lighter-colored materials have obvious color changes against dark objects.
(6) Object surface texture
The emission effects produced by different problem suits are also different, and the difference can be found in the colorimeter and visual inspection.
