Process Features: KANA coating liquid replaces PVC protective film, allowing for lettering and easy transfer without peeling. There are no issues with shrinkage, curling, or bubbles. It boasts strong resistance to friction and damage, yellowing, rainwater, high and low temperatures, and aging. Depending on the weather resistance of the printing ink, it can last for over 3 years. For example, when using efi/Canon original ink, the colorfastness and color difference data are excellent after 5 years. The cost advantage is evident, and installation and construction are convenient. The surface of the image is bright and smooth, easy to clean, with unchanged light transmittance and light reflection coefficients.
