For color viewing booths from GTI Graphic Technology, Inc., small stains can be cleaned with mild soap and water. A mild solvent can be tried, but test it on a non-critical part of the booth (the underside for instance) to make certain the solvent will not remove any of the paint. For larger or stubborn stains, a new booth component (e.g., viewing surface) can be ordered and the pieces replaced.
Yes, providing each booth meets the specifications of ISO 3664:2009, have the same surround color (i.e., Munsell N8), and have a CRI of 90 or better.
No. Scientists have divided Ultraviolet energy into three very distinct regions; UV A, UV B, and UV C. UV A (also known as “Near UV” because of its close proximity to the Visible spectrum) are the wavelengths from 315 to 400 nm. The skin is sensitive to wavelengths below 320 nm. GTI ColorMatcher® and Graphiclite® lamps emit very little energy below 325 nm. UV B and UV C energy are used in medical and biocidal applications.
NO! Like all products, lamps are manufactured to meet certain needs. For most commercially available D50 and D65 lamps, the manufacturers are trying to produce long production runs and low manufacturing costs to gain the highest profits. Many do not render colors as well as lamps produced specifically for color matching applications. Additionally, they may not emit enough Ultraviolet energy to accurately simulate natural daylight. Make certain lamps have a high CRI value (92 or better) and a CIE Publication 51 Rating of at least B/C.
However, having a high CRI or Publication 51 rating may not be enough. Light booth manufacturers have their lamps formulated specifically to be part of a viewing system. This includes the reflector, the lamps, the diffuser, etc. Slight changes in the formulation can create a slight color cast that will influence color assessment. When lamps from another vendor, even another viewing booth manufacturer, are used in place of the original equipment lamps, the color viewing booth may no longer meet the ISO, ASTM, or CIE Publication 51 ratings specified by the manufacturer. Always use the lamps specifically recommended for the viewing booth you have.
Not all 5000 Kelvin lamps are the same!
