D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries. 

Ensure the source, viewing angle, and background are all neutral and standardized, and the samples are clean, and positioned for a side-by-side comparison under each light condition.

Ambient light, heat, and moisture levels should be regulated. The use of colored walls and reflective surfaces should be avoided, as they can damage the assessment of the sample colors visually.

Gloss is a broad term to describe the reflectivity of a surface. Whereas high gloss is a specific term that has the highest reflectance (usually more than 70 GU). High gloss finishes are shiny, mirror-like, and exhibit more surface blemishes than lower gloss finishes.

Flickering lamps, color shifts, and uneven lighting are common faults, which can be corrected by changing the tubes, cleaning the interiors, and re calibrating the light system.

Always a pre-production sample before mass production; Always final Inspection before shipment; 

Pantone light boxes are mainly used for standardized color viewing and color consistency verification across multiple industries to ensure accurate color evaluation under uniform light conditions. Core Application Industries like Textile & Garment Industry, Printing & Packaging Industry, Paint, Ink & Coating Industry, Plastic & Electronic Product Industry, Cosmetics & Food Industry

Take L*a*b* readings of two samples using a colorimeter or spectrophotometer and calculate color difference using the 3 formula (Delta E). The difference in 0 is the reported Delta-E, which shows how visible the change is, whereas the thresholds define the acceptability as per the application requirements.

Assembling the light booth entails connecting the panels, fixing the light fixtures, fitting the tubes, and calibrating the lights according to our 3nh manufacturer’s instructional and safety guidelines.

A light booth for color matching usually contains D65 (daylight), TL84 (store), A (incandescent) and UV light. LED may also be used in modern time for additional color matching.
