GTI was founded in 1975 to design and manufacture critical color viewing/inspection systems for the most demanding clients. Success over the past 35 years has been the result of our relentless pursuit of improved consistency and accuracy of our Graphiclite Color Viewing Systems, CMlite Color Matching Booths, and proprietary color viewing lamps. Our precision is guaranteed by an in-house spectroradiometric laboratory and our 100% measurement and verification production process.
