Color Viewing Lamps For Critical Color Viewing and Inspection per ISO 3664:2009

GTI Graphiclite 100 lamps are manufactured with a unique blend of fluorescent phosphors that is unequaled by any other 5000 Kelvin lamp in the industry. GTI lamps produce a true full spectrum white light which renders colors with the highest degree of accuracy and efficiency.

When used in GTI viewing systems, the Graphiclite 100 color viewing lamp produces an actual system CRI approaching 95.

GTI viewing systems include a reflector, diffuser, the booth structure, geometry of illumination, and Graphiclite 100 lamps. A change in this system’s formulation can create a slight color cast that will impact color assessment, resulting in a viewing environment that is not ISO compliant. To maintain an ISO 3664:2009 compliant viewing system, use only GTI Graphiclite 100 color viewing lamps and relamp regularly. ISO 3664:2009, which specifies a D50 daylight viewing condition, is used by the graphic arts and photographic industries.

D50 (5000K) – A near white light source used for visual evaluation in printing, packaging, photographic, and other graphic art industries. It is the specified source in ISO 3664:2009. It has similar amounts of red, green, and blue energy. It neither accentuates nor subdues color, a prime requirement when viewing press sheets and original images (i.e., photographs) since they usually have many colors within the product to be evaluated.
