Printing, packaging, photographic, and other graphic art industries have adopted ISO 3664:2009 as their international standard for viewing color. ISO 3664:2009 specifies a color temperature of 5000K and spectral power distribution of CIE D50. D50 (5000K) is a near white light source and has similar amounts of red, green, and blue energy. It neither accentuates nor subdues color, a prime requirement when press sheets, original images, or printed material since they usually have many colors within the product to be evaluated.
ISO 3664:2009 requires that viewing conditions meet strict specifications with regard to color quality, light intensity, evenness of illumination, viewing/illumination geometry, and surround conditions. The best way to ensure that you meet these requirements is to use a color viewing booth that conforms to the ISO 3664:2009 standard. All GTI Graphiclite color viewing systems are compliant with the ISO 3664:2009 standard.
The lamps are the most important part of the viewing booth. GTI’s inhouse spectroradiometric laboratory and a 100 percent measurement and verification process guarantee that our lamps consistently deliver an excellent match to the D50 spectral power curve.
