A Detailed Guide to Light Fastness Testing

[fyitester]

Color accuracy and performance are two of the most important factors for manufacturers. From plastics to fabrics, the durability and longevity of color is the single most important indicator of quality.

Most products are designed for outdoor environments, where they are constantly exposed to the sun, especially textiles.

If a product fades under the sun, it might be a reason to stop production, but most items are already sold by then. Light fastness testing helps anticipate and prevent these product recalls ensuring quality.

This guide breaks down light fastness testing, standards of color fastness to light test, and applications of a tester like the YG611M. https://fyitester.com/light-fastness-testing/
