Comparison of color fastness quality Between Direct To Film, Direct to garment and Sublimation

This study aims to compare the print quality and color durability of textile printing using Direct to Garment (DTG), Direct to Film (DTF), and Sublimation. The evaluation focuses on image sharpness, the ability to reproduce fine lines and small text, ink adhesion, as well as color gamut comparison and color fastness after washing. The experiment was conducted by designing a test form consisting of the ECI2002 standard image, text, and various line widths. The test form was printed on cotton fabric using all three printing methods and then washed according to ISO 6330 standards with detergent and chemicals for ten cycles. After each wash cycle, the printed samples were evaluated by measuring color values and capturing images using a digital microscope with 1600x magnification. The color difference and color gamut were analyzed, along with sharpness and text reproduction. The results showed that the Sublimation printing system exhibited

the highest ink adhesion and washing durability, with minimal color changes on the fabric and the best sharpness and text clarity. In contrast, the DTG printing system demonstrated the lowest washing durability and the highest color difference values. In conclusion, DTG printing has lower print quality and color durability compared to DTF and Sublimation printing
