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.

The color measurement test applies a colorimeter or spectrophotometer to evaluate the way a sample reflects or absorbs light. It is given in objective color values (L*a*b*, RGB, or absorbance) and is usually contrasted to a standard in quality control or compliance.
In a Pantone light box, the tubes last around 2000 to 3000 hours, after which the brightness and color should be assessed for replacement.
Gloss level is not given out in percentage but in gloss units (GU). In practice, however, 100 GU is considered 100 percent reflective. To contrast visually, the 20-40 GU is a low-gloss surface, and 85 or more is almost 100 percent mirror-like reflection.
Measuring zinc coating thickness is most commonly using magnetic induction. The gauge measures how far the magnetic probes are to the metal base under the zinc. This is the most reliable way to measure the thickness and the preservation of the galvanization.

The five common gloss levels are:
1. Flat/Matte (0–10 GU)
2. Eggshell (10–25 GU)
3. Satin (26–40 GU)
4. Semi-gloss (41–70 GU)
High Gloss (71–100+ GU)
These levels vary slightly depending on industry and standards used.
To keep the light box calibrated and to ensure accurate and steady lighting, clean the inside, replace the lamps when needed, check the calibration and record the hours use
