A colorimeter is a quick and inexpensive method to measure color and to control color in a material or solution. It is used to maintain color consistency during production and to check the chemical concentration. It also assists with the quality control of labs, food, textiles, and pharmaceuticals.
Pick a haze meter that correlates with your materials, precision needs, and applicable testing protocols. For lab-level precision, a bench-top version is advisable; for a rapid field check, a portable haze meter is appropriate. International standards must be met at all times.
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.
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.
The gloss scale is normally measured against the scale of 0 to 100 gloss units (GU). The scale is zero at matte and 100 at a mirror. Other very smooth surfaces can be over 100 GU at lower angles, such as 20°.
A digital coating thickness gauge is used to measure the thickness of dried paint. It measures coating thickness specification non-destructively, helping to maintain consistent quality and performance.
An 18% gray background reduces distractions and color bias, helping in a more accurate assessment.
An 80 gloss surface will reflect less light as compared to a 100 gloss surface. Both are said to be high gloss, although 100 GU (or higher) reflects almost as much as a mirror. The distinction can be slight in graphic terms, but major in specific uses.
To take care of a haze meter to make it last longer, ensure that it is cleaned, recalibrated regularly, and stored in a dry, dust-free place.
