Introducing the Color Fastness Automatic Grading System

The Color Fastness Automatic Grading System is a cutting-edge instrument designed to objectively and accurately assess the color change and staining of textile samples after various fastness tests. Moving beyond subjective visual evaluation, this system utilizes advanced optical technology and intelligent algorithms to provide precise, repeatable, and consistent grading results.

It significantly enhances efficiency and reliability in quality control, R&D, and compliance testing for manufacturers, laboratories, and research institutions. By automating the grading process, it minimizes human error, reduces labor intensity, and ensures global consistency in color fastness assessment.

Application Scope

The color fastness automatic grading system is used to evaluate the color fastness of textiles, including color staining fastness and color change fastness. It can also assess products’ resistance to friction (dry and wet friction) fastness, light fastness, and other performance characteristics. Traditionally, color fastness grading is performed by trained and experienced graders using standard light source boxes and gray scale equipment.

Instrument Features

1. Combines LED active lighting and RGB imaging technology to accurately capture the product’s color and appearance, enabling digital grading of color fastness.

2. Automatically grades color change fastness, staining fastness, light fastness, and a series of other performance tests such as resistance to friction.

3. Optionally uploads color fastness data to ERP systems, facilitating enterprise product quality management and data sharing.
