There is no generic mathematical formula for gloss value. Rather, it is measured directly with a gloss meter, which compares how strongly reflected light from a sample matches a standard (typically black glass with a known reflectance).

An inappropriate viewing angle may lead to reflections or color shifts in the light. The correct angle of 45 or 0 will provide the real color of the assessment without the distraction of glare.

Ambient light may affect the test results and must therefore be kept to a low level for accurate haze meter results. 

Our machine is packed by standard export wooden box, it won’t be damaged. We’ve delivered many testing machines abroad by sea or by air without damage.

When using a Pantone light box, each sample should be positioned flat and nearby the other samples, but not overlapping. Each one should also be in the middle of the light box, and the surfaces of the light box should be clean and non-reflective.

A colorimeter or spectrophotometer should be used to measure the color of a solution. The instrument directs light through the liquid and quantifies absorbance at certain wavelengths. The values obtained indicate the color intensity of the solution and, by default, the concentration of the solution.

L*a*b* is an L*a*b* color space. The L* is a measure of lightness (as 0 = black, 100 = white), a* indicates the green to red axis, and b* indicates the blue to yellow axis. It is also common in color measurement in terms of precision and reliability.

Depending on model and location, delivery time is usually 2-4 weeks for standard models and 4-6 weeks for built- to-order ones. 

 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.

Lightbooths come in different dimensions. A typical tabletop model occupies 0.5-1 m². The bigger industrial variants take up 2-4 m².  If you have special requirements, we can customize the product according to your size
