FAQs About  Spectrocolorimeter

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.


A colorimeter is sufficient when measuring similar materials or batches with stable conditions. Suitable for fast, low-cost color checks where high precision is not required. Quick quality control in plastics, paint batch consistency, food color grading (e.g., fruit ripeness), and basic printing checks.

A spectrophotometer is recommended when you need professional, maximum color accuracy or when testing materials with variable surfaces – such as glossy or textured samples. Like textile dye formulation, cosmetic shade matching, medical device color calibration, high-end printing (e.g., packaging for luxury goods), and material spectral research. learn more Understanding Spectrophotometric Parameter Measurement


A Spectrophotometer color measuring device objectively determines the color of a surface. It is used wherever accurate color matching, reproducibility or deviation control is needed – for example in quality assurance, product development or incoming goods inspection.

Spectrophotometer color measuring devices primarily perform three key tasks:

Capture color information: They detect light reflected, transmitted, or emitted by a sample using optical sensors.
Quantify color data: They convert the captured optical signals into standardized numerical values, such as RGB, CMYK, or CIELAB coordinates.
Compare color consistency: They compare the measured color data of a sample against a target or standard to assess color accuracy and uniformity.


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.


The accuracy of colors is determined by comparing the values of the colors (L*a*b*) of a sample with a standard reference sample using tools such as spectrophotometers. The variation is measured as ΔE. The smaller the value of ΔE, the more accurate, the nearer to the target color.
