FAQs About  ISO Test Charts

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 -128 to +127. Positive values represent red tones, while negative values represent green tones.
B (Yellow-Blue Axis): Ranges from approximately -128 to +127. Positive values represent yellow tones, while negative values represent blue tones.


To extend the life of a haze meter, keep the instrument dust-free and clean, regularly calibrate it, and control for a stable dry storage. For better results, avoid letting the optics dry, and leave the meters under sunlight. For optimal performance, have the meter professionally serviced once a year.

Inconsistent results from a haze meter can stem from issues like calibration, dusty haze meter optics, inadequate power supply, and improper measurement technique. If you have any questions, you can contact our Haze measurement experts


Inaccurate color rendering, mismatched results, and noncompliance with ISO 3664 or ASTM D1729 can occur when there are deviations.

The Colour Assessment Cabinet (CAC) is a controlled environment used for the visual evaluation of color wherein the light sources are consistent.


A colorimeter is used to measure absorbance at selected wavelengths with the help of filters, which is suitable for rapid comparison of colors. A more advanced spectrophotometer has a monochromator. It can measure a larger range of the spectrum of light and is more accurate. You can also get detailed color data at visible and non-visible wavelengths.
