Big Color Matching Cabinet Color Assessment Cabinet 6 Light Sources

1. Uses
Color matching cabinet is an equipment designed for the visual evaluation of shade and color differences under standardized and controlled lighting conditions. Multiple light sources provide an essential tool for visual color assessment, comparison of color variation, and detection of metamerism (when color samples appear to match under one lighting condition but distinctly change when viewed under a different lighting condition).

2. Specifications

Instructions for Lamp Cabinet

1. Provide several light sources, i.e. D65, TL84, CWF, UV, F/A
2. Apply microcomputer to switch between the light sources quickly.
3. Super timing function to record use time of each light source separately.
4. All fittings are impored, ensuring quality.

Color Assessment Cabinet,suitable for all industries and applications where there is a need to maintain color consistency and quality-e.g. Automotive, Ceramics, Cosmetics, Foodstuffs, Footwear, Furniture, knitwear, Leather, Ophthalmic, Dyeing, Packaging, Printing, Inks and Textile.
Since different light source has different radiant energy,when they arrive on the surface of an article,different colors display. With regard to color management in industrial production,when a checker has compared the color consistence between products and examples, but there may exist difference between light source used here and light source applied by the client.In such condition, color under different light source differs. It always brings following issues: Client makes complaint for color difference even requires for rejection of goods, seriously damaging company credit.
To resolve the above problem, the most effective way is to check good color under same light source. For example, international Practice applies Artificial Daylight D65 as standard light source for checking goods color.
It`s very important to use standard light source to chenk color difference in night duty.
Besides D65 light source, TL84, CWF, UV, and F/A light sources are available in this Lamp Cabinet for metamerism effect.

4. Lamp Cabinet Performance

1. 1. Hepachromic artificial daylight acknowledged by CIE, 6500K color temperature.
   2. Lighting scope: 750-3200 Luxes.
   3. Background color of light source is Neutral Grey of absorbance.In using lamp cabinet, prevent outer light from projecting on article to be checked. Don`t place any unconcerned articles in the cabinet.
   4. Making metamerism test.Through microcomputer, the cabinet can switch between different light sources in very short time to check color difference of goods under different light source. When lighting up, Prevent lamp from flashing as home fluorescent lamp is lighted.
   5. Correctly record use time of each lamp group. Especially D65 standar dlamp shall be replaced after being used for over 2,000 hrs, avoiding error resulted from aged lamp.
   6. UV light source for checking articles containing fluorescent or whitening dye, or be used to add UV to D65 light source.
