Automotive, Ceramics, Cosmetics, Foodstuffs, Footwear, Furniture, knitwear, Leather, Ophthalmic, Dyeing, Packaging, Printing, Inks and Textile.
It is very important to use standard light source to check color difference in night duty.
Besides D65 light source, TL84, CWF, UV, and F/A light sources are available in this color light box for metamerism effect.
- Color matching cabinets provide several light sources, i.e. D65, TL84, CWF, UV, F/A
- Microcomputer to switch between the light sources quickly.
- Super timing function to record use time of each light source separately.
- All fittings are improved, ensuring quality.

How to use color assessment cabinet correctly?
What is colour matching cabinet？
Colour matching cabinet,also called color viewing light box or colour matching box,is a light booth for color matching.It can be easily felt in our daily lives that under different lighting conditions, the color of an object would appear to be different to us to certain extent. This is because different light sources own their own radiating energy, when the light hits on the object, different colors would be reflected and appeared.
Similar situation applies to the manufacturing industry. For example, when quality assessors have done their job to make sure that the color of the product is right, but complaints from the customers regarding the difference in color are still received. Sometimes it can even lead to the request for refund or return for the product and this would bring negative impacts to the reputation of that company.
To solve this problem effectively, the easiest approach is to do the color assessment test through color assessment cabinet and color matching cabinet under the same source of lighting with controllable requirement. For example, use the popular white light source- d65 light box for the test. Otherwise, the test would be meaningless and untrustworthy.
How to use the color assessment cabinet correctly?
- Objective Angle
Below is the features that a color assessment cabinet should have. Note that the angle of observation affects the result of quality assessment directly and there are only two angles of observation that can be used. And, they are:
- Zero degree light source, observe at the angle of 45 degree (0 °-45 °). i.e. The light source shoots perpendicularly on the specimen, or zero degree of incident angle, and the observer should observe at the angle of 45 degree.
- Light source at 45 degree
Light source at 45 degree and observe at the angle of zero (0 °-45 °). For this setup, the use of 45°fixed angle table is involved so that the light source shoots on the specimen at the direction of 45 degree and the observer should observe at the angle of zero degree(perpendicular to the specimen).
- Positioning of the specimen for the 45°light source test
Note that for whichever approach from above, the specimen should always be placed at the center of the color matching light box to reduce the effect of the outside light source on the result. Besides that, the most important thing when it comes to comparing the colors of two or more objects, avoid stacking the objects. Instead, place them side by side to do the comparison.
