Vertical Product Inspector – Textiles
The VPI/T viewing system helps the textile industry evaluate textiles and apparel as per AATCC Test Method 9 and other AATCC test methods such as soil release, wrinkle retention, and more. The VPI/T light levels meet the specifications outlined by the AATCC.
Color Rendition Demonstrator
The CRD is designed for demonstrating the effects different light sources have on identical color samples. The three compartment viewer demonstrates color rendition of store light, 6500K daylight, and home light. Viewing area of each compartment (H × W× D) is 11" × 9.5" × 7.5".
Simultaneous Color Viewer
The SCV helps detect metamerism and test color harmony by allowing a visual side-by-side comparison of colors under four light sources: daylight, LED, store light, and home light. A UV light allows for the detection of optical brighteners, whitening agents, and fluorescent dyes and pigments.
Available Light Sources
