The research paper aims to the analysis of light fastness of inkjet printed textile products to the artificial light. The artificial light used here is a xenon arc lamp and two polyester substrate having different screen counts is selected. The higher screen count shows less color variation to the artificial light as compared to the color variation on less thread count substrate. The ink used for inkjet printing is locally made at Flashjet inks, Chennai and the cost is less. The artificial lights are rich in various ranges of electromagnetic spectrum especially in ultra violet region. Various researches show the UV light is responsible for 50 % light fastness, 25% by heat and 25% by normal light rays. In this research, Yellow color shows higher color variation. The solid patch color variation is higher than the tint patch color variation. Some research shows higher level multi ink layers have less color variation. The one of the main method to prevent the light fastness is the addition of cationic UV absorbers as the ingredient in the printing ink.
