WF standard light source color light box Introduction: The standard light source color light box is widely used in the color management fields of textiles, plastics, paints, inks, printing and dyeing, printing, pigments, packaging, ceramics, leather, cosmetics, etc., to accurately check the color deviation of goods and improve product quality. And market competitiveness. Especially in cloudy and dark nights, it is especially important to use a standard light source to detect the color deviation of the color light box. Product performance: D65 uses the artificial fluorescent lamp D65 approved by the International Institute of Lighting (CIE) as the basic illumination source. In addition to being used as contrast color, the D65 light source is also defined by most of the world's society or group as the illumination source when the gray scale is compared. Ultraviolet light source (Ultra: Violet llluminant) Due to the widespread use of fluorescent and whitening dyes in industrial production, the best way to detect these effects is to use an ultraviolet light source because the ultraviolet light is irradiated with fluorescent light. The substance of the agent will produce a noticeable change in brightness that is easily detectable by the naked eye. F/A Family Light Source (Filament Lighting) is suitable for color management under the light source in a home or hotel room, such as underwear, bedroom products and other products. CWF / TL84 / U30 Some customers require this source for color matching. For example, US merchants often require Cool White Fluorescent (CWF) light source. European and Japanese merchants require Triphosphor Lamp P15 (TL84) light source. U30 is another type. American commercial light source. The illumination of the light source ranges from 750 to 3,200 lux (Luxes). Background color and brightness are very important when performing color work. Because color is a subjective sensation, comparing colors in different backgrounds can produce different results. Therefore, all background colors are specified as Neutral Grey, and the reflectivity must be less than one-third of the incident light. Record the usage time of each light source separately (it is recommended to replace the light pipe after 2,000 hours) to avoid detection errors caused by aging of the light pipe. It has the ability to test the metamerism effect. The so-called metamerism effect means that under a certain light source, the color of the sample appears to be the same as the requirement, but under another light source, the color is different and cannot be accepted.
