I. Descriptions

Dyeing, Packaging, Printing, Inks and Textile. 

 

 

 

 

 

 

 

 

 

 

Since different light source has different radiant energy, when it reaches on the surface 

of an article, different colors will reflect.    With regard to color management  in 

industrial production, when an inspector is comparing the color consistency between 

products and samples, but there may be color differences due to the light sources used 

between in the production premises and those used by the client.    In this case, color 

under different light source might result differently.    It may create some unnecessary 

issues that the clients file a claim for color discrepancy or eventually result in rejection 

of goods, which can affect the company’s creditability. 

 

 

 

 

 

 

 

 

 

 

To resolve the above problem, the most effective way is to check the color under same 

light source. For example, international practice applies Artificial Daylight D65 as 

standard light source for checking the color of the goods. 

 

It's very important to use standard light source to check color difference in night shift. 

 

 

 

 

 

 

 

 

 

 

Besides D65 light source, TL84, CWF, UV and F/A light sources are available in this 

Lamp Cabinet for metamerism effect.
