Color/Gloss Measurement
Color and gloss are important parameters for material surface inspection. They provide an objective quantification of the appearance characteristics of a material's surface, allowing for quality control, consistency assessment and comparison between samples.
T, C&A Lab offers specialized color/gloss measurement services for objective assessment of visual properties, which help in quality control and ensure consistent appearance across a variety of industries such as automotive, paint, plastics and cosmetics.
T, C&A Lab's color measurement services
Color measurement is the quantification of the perceived color of a material using objective metrics. It involves the measurement of various color attributes such as hue, saturation, and brightness.
T, C&A Lab uses spectrophotometers to capture and analyze the spectral reflectance or transmittance of materials. These instruments emit light onto the material and measure the intensity of the reflected or transmitted light at different wavelengths. The collected spectral data is then used to calculate color values based on standard color spaces. The measurements are carried out under defined UV illumination and geometry.
The standards for color measurement are based on DIN 5033-3, DIN 6174, and ISO 7724-3.
T, C&A Lab's gloss measurement services
In addition to color measurements, gloss measurements are often required. Gloss is the perception of how shiny or reflective a material's surface is. It is an important aspect of surface quality and is measured using a gloss meter. A gloss meter illuminates the surface of a material with a light source and detects the amount of light reflected at a specified angle.
T, C&A Lab's gloss meters typically measure the amount of light reflected from a surface at a specific angle, such as 20°, 60°, or 85°, depending on the material and the desired evaluation criteria. Different angles are used to assess gloss in various applications. For example, a low angle such as 20° is suitable for high gloss surfaces, while a higher angle such as 85° is suitable for matte or low gloss surfaces.

Integrated services for color and gloss measurement
In material surface inspection, color and gloss measurements are often combined to provide a comprehensive assessment of surface appearance. By considering both color and gloss values, manufacturers can ensure that visual characteristics remain consistent from batch to batch or product to product.
T, C&A Lab uses separate instruments to measure color and gloss independently, or some equipment is capable of capturing both parameters simultaneously. These integrated systems provide convenience and efficiency in evaluating surface appearance.
