GB/T 22771-2008 "Graphic technology - Assessment of light fastness of prints and printing inks using filtered xenon arc lamp" specifies the method for evaluating the light fastness of prints and printing inks using a filtered xenon arc lamp, applicable to various types of prints and printing inks. By simulating natural light conditions with a xenon arc lamp, accelerated aging tests are conducted on samples, and the light fastness is assessed by comparing color changes before and after the test. The detection requires instruments such as a filtered xenon arc lamp aging test chamber, a colorimeter, and standard gray scale cards, providing a basis for judging the color stability of products used outdoors.
