ColorMatcher® Series

When an item is viewed, the color we see is a result of the color quality of the light source and the reflective characteristics of the item. As a result, when attempting to achieve an accurate color match, colors can appear to match under one light source and then appear significantly different under another light source.


Premier Viewing Booths for Color Matching and Inspection
Industry standards require that viewing booths meet strict specifications in regard to color quality, light intensity, evenness of illumination, viewing/illumination geometry, and surround conditions.

Meeting Industry Standards

The GTI ColorMatcher Series is designed to meet all industry requirements. All ColorMatcher models conform to the ASTM D1729, ISO 3668, SAE J361, BS-950, AS 1580, AATCC Procedure #9, TAPPI T-515, and TAPPI T-1212 viewing standards. All booths are supplied with a certificate of product conformance (NIST traceable).
A GTI ColorMatcher viewing booth will enable you to make visual color inspections with confidence. Four model sizes are available to accommodate nearly any size sample (see reverse).
