The color of chemical products is measured by using a colorimeter or spectrophotometer. The instruments measure the amount of light that gets absorbed or reflected by a substance. It may be used to determine concentration, purity, or compliance with product standards.

To determine haze, haze meters are used in multiple industries such as plastic, glass, film, coating, and displays. This ensures that all optical quality of the product is in the appropriate specification, including aesthetic compliance and meeting the intercontinental quality standards.

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

Standard light sources make sure that the results of color evaluations are comparable and consistent, no matter when and where the assessments are made, or the varying production runs.

The LAB color space defines colors in a three-dimensional model: Lightness (L), red–green axis (a), and blue–yellow axis (b). It's a globally recognized standard supported by most modern color measuring devices. CIELAB is a standardized, device-independent system designed to map all visible colors that the human eye can perceive.

The LAB color space uses three values to define any color, each representing a specific dimension:

L (Lightness): Ranges from 0 to 100. It measures the brightness of the color, where 0 is pure black and 100 is pure white.
A (Red-Green Axis): Ranges from approximately -96 to +127. Positive values represent red tones, while negative values represent green tones.
B (Yellow-Blue Axis): Ranges from approximately -96 to +127. Positive values represent yellow tones, while negative values represent blue tones.

The gloss of the paint is defined by the measurement of light reflection at the surface of the paint with the help of a gloss meter. The angle and quantity of light reflected determine the level of gloss, with smoother and reflective surfaces having a higher level of gloss.

To answer this question, you first need to clarify your specific needs: 

• Is it for simple color quality control (QC)?

• To coordinate with supply chain color management?

• To monitor on-line color stability?

• Do you require computer color matching or production color correction?

• What is your budget?

• Systematic supervision and evaluation of color performance in dyed products?

If you aren’t fully clear about your requirements at the initial stage, our color management engineers are ready to communicate with you. We will recommend solutions tailored to your needs. When conditions permit, we can provide prototype demonstrations and trial testing to ensure the instrument meets your practical application requirements.

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

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. 

Smooth and uniform surfaces with a large amount of reflected light directly result in high gloss. Some of the factors are the smoothness of the surface, the type of paint that is being used, the thickness of the coating, and curing. The lesser the surface irregularities, the greater the gloss.
