The correct use of color light boxes can not only provide more accurate measurement results and color detection, but also greatly help us extend the service life of colorimeters. So we color inspectors must pay attention to our habits when using color matching light boxes. It is necessary and important to develop good and correct color detection habits. Let's discuss the correct operation method of the lightbox together now.

1The selection of D65 light source for dyeing is very important. The YQ60 (4), YQ60 (5), and YQ60 (6) D65 light tubes are equipped with Aiseli light tubes, which are produced in Canada and have the model F20T12/65 6500K. The color matching is very accurate. Some customers have experienced inaccurate color matching when purchasing cheap Philips D65 lamps, resulting in significant losses of tens of thousands of units. Choosing YQ60 (5) and YQ60 (6) can solve the problem of inaccurate color matching.

2、 Observation angle:

The observation angle will directly affect the evaluation results. According to the standard, there are only two Observation angles can be used, which are:

aZero degree light source,45Degree observation（0°/45°）

The light source is irradiated onto the test sample from a zero degree (vertical) incident angle, and the observer45Observe the test sample, as shown in the following figure: 45Degree observation（0°/45°）

B、45Degree light source, zero degree observation（45°0°）

In this layout, a specific one must be used45Inclined platform（45°T：H Table）,Using a light source from45Illuminate the test sample with the observer observing it from zero degrees (perpendicular). As shown in the following figure:Zero degree observation（45°0°）

3、 Placement of test samples

Regardless of using any of the above observation methods, it must be noted that the test sample should be placed in the middle of the lightbox as much as possible to reduce the influence of external light sources. In addition, it is important to avoid overlapping two or more colors when comparing them. It is better to place them side by side in a color matching lightbox for comparison.

4Light box maintenance

A comprehensive maintenance plan is necessary to ensure that your color light box is in standard condition for a long time; Be careful when using, if you want to dirty the paint inside the lightbox, if you find stains or peeling paint, you should immediately send employees to correct or replace the inner wall panel, and regularly check the usage time or brightness of the lamp tube, etc. These services can be provided by the seller.

The above is the guarantee for the correct and long-term use of color light boxes. As long as the color detection results are measured according to these steps, they will be accurate, and the service life of the light box will also be relatively long. So operators using lightboxes must pay attention to these details.

Standard light source boxes are widely used in various industries such as textiles, toys, printing and dyeing, plastics, paints, inks, printing, pigments, chemicals, ceramics, footwear, leather, hardware, and food for color management and visual evaluation of color fastness, color matching sampling, identification of color differences and fluorescent substances. They enable samples, production, quality inspection, and acceptance to be carried out under the same standard light source, accurately checking the color deviation of goods and ensuring that the color quality of goods meets requirements. Thus improving product quality and market competitiveness.
