Double Copper Paper ColoriMeter

The double-sided coated paper colorimeter measures the reflected light from the paper surface using optical sensors, converting colors into numerical data. It is used to monitor color consistency in printed materials made from double-sided coated paper, serving for quality control and batch matching in the printing and packaging industries.
Selection
When selecting a double-coated paper colorimeter, it is essential to consider the measurement aperture matching the paper texture, ensuring the instrument's repeatability meets the production error range, compatibility with industry-standard color spaces, an operation interface suited to workshop environments, and maintenance costs aligned with usage frequency.

Colorimeter controls batch color difference in plastic and rubber films.
This article primarily discusses how to use a colorimeter to control color differences in the production of plastic and rubber films. It explains the working principle of the colorimeter, which involves converting colors into numerical values represented by L, a, and b values, and then calculating the color difference.
Colorimeter evaluates the change in yellowing index of transparent resin.
This article introduces how to use a colorimeter to measure the yellowing index changes in transparent resin. Transparent resin can turn yellow over time or due to environmental influences, and the yellowing index can quantify the degree of color change.
Application of Colorimeters in Color Management for Packaging and Printing
This article mainly discusses the application of colorimeters in color management for packaging and printing. A colorimeter is an instrument used to measure color, capable of converting colors into numerical values, such as representing them with L*a*b* values.
Multi-angle colorimeter detects color changes in pearlescent coatings.
Pearlescent coatings contain special flake pigments that produce color effects that vary with the viewing angle, known as "goniochromism." Traditional single-angle measurements struggle to accurately capture this characteristic.
Application of Colorimeters in Controlling Color Differences in Paint Batches
This article introduces the role of colorimeters in controlling color consistency in paint production. Since human judgment of color is easily influenced by lighting and subjective factors, colorimeters quantify color differences in the CIELAB color space by measuring spectral data, providing an objective basis for production.
Application of Colorimeter and Color Matching Box in Pigment Color Inspection
A colorimeter and a light booth are two primary tools in pigment color inspection. The colorimeter measures color through photoelectric principles, while the light booth provides a standardized light source environment for visual evaluation of color effects, metamerism, and other phenomena.
