Observation Angle:
The following points are all the facilities required for the Color Assessment Cabinet, and the viewing Angle will directly affect the evaluation results. According to international standards, there are only two observable angles that can be used. They are:
A, zero light source and 45 degrees observation (0 °, 45 °), the light from zero (vertical) incident Angle on the sample, sample watchers from 45 degrees.
B, light source and 45 ° inclined channel
45 degrees of light source, zero observation (0 °, 45 °), the layout must use specific 45 degrees of inclined (45 ° Fixed Angle table) making from 45 degrees of light source on the samples, sample watchers from zero (vertical).
The location of the 45 ° light samples:
Regardless of any of the above observation methods, it is important to note that the test sample is placed in the middle of the light box as far as possible to reduce the influence of the external light source. In addition, the most important thing is that when you need to compare the colors of two or more objects, you should also try not to overlap them and observe them, preferably by placing them side by side in the box.
Light box maintenance:
A perfect maintenance plan can ensure that your light box is in standard condition for a long time: if you use it, be careful not to pollute the inner wall of the lamp box; If you find any stain or paint peeling, you should immediately send someone to correct or replace the inner wall panel, and always check the use or brightness of the lamp.
Requirements for the implementation of environmental factors in color:
All in on test samples according to the body will have the opportunity to foreign must avoid light, such as the window within the scope of the field of vision, also should be fitted with a gray curtain to cover it, so in a dark room used for color light box is the most ideal. Another thing that is often overlooked is that the color light box must not be placed in other sundries.
Have test the functionality of the same color different spectrum effect:
So-called homochromy different spectral effect, is that under a light source, the samples with the colors displayed requirement is the same, but in another light, the color difference will not be accepted. Under D65 light, the color is not much difference with the standard but in A light under the original sample color can't accept it. Therefore, all the color light source device, must be equipped with two or more light, to test the same color vision effect.
Convert light source requirements:
According to the daily life experience, in our eyes, like having a register, when change color in a very short time, we can clearly feel. So in observing the same color vision spectrum, if want to change the light source, it must be done in flash, do not like lighting lamp we use in our everyday, after to twinkle Gao Zhao, because that would stimulate the eye, affect the review result.
Uv light source:
Because of the current industry, fluorescence and whitening dyes are commonly used, and the best way to detect this effect is to use a non-uv light source, which must not be partial.
Position of lamp tube:
Although there is no specific requirement for the arrangement of the lamp tube, the distribution position must be in the color light box with a uniform light source and must not be partial to the side.
