Color Assessment Cabinet
Product description:
Standard light source colorimetric light box is widely used in textile, plastic, paint, ink, printing, dyeing, printing, pigment, packaging, ceramics, leather, cosmetics and other industries in the field of color management, used to accurately calibrate the color deviation of goods, improve product quality and market competitiveness. It is especially important to use the standard light source to detect the color deviation of goods on cloudy days and dark nights.
Technical parameters:
D65 The use of artificial fluorescent lamps D65 approved by the International Commission on Illumination (CIE) as the basic lighting source, D65 light source in addition to being used as a contrasting color, but also defined by most of the world's societies or groups as a gray-scale contrast when the lighting source.
UV Ultraviolet light source (Ultra:Violet llluminant) .Due to the widespread use of fluorescent and whitening dyes in industrial production, the best way to detect this effect is to use a UV light source, because UV light in the irradiation of fluorescent dyed substances will produce obvious changes in brightness, so that the naked eye can be easily detected.
Family Light Source (Filament Lighting) is suitable for color management instead of observing colors under a light source in a home or hotel room, such as underwear, bedding, and other products.
CWF / TL84 / Some customers require the use of this light source for color matching, such as the United States customers often require the use of Cool White Fluorescent (CWF) light source, European and Japanese customers will require the use of Triphosphor Lamp P15 (TL84) light source. Illumination of light sources in the range of 750 to 3200 luxes.
When performing color matching work, the background color and lightness are very important. Since color is a subjective perception, comparing colors against different backgrounds will produce different results. Therefore, all background colors are specified as Neutral Grey, which must be less than one-third the reflectivity of the incident light. Separate records of the use of each type of light source, (it is recommended that the use of 2,000 hours after the replacement of the light tube), to avoid the detection error caused by the aging of the light tube.
