Print adhesion refers to the ability of a printed material to stick to a substrate, such as paper or plastic. This property is crucial in various printing processes, including inkjet and offset printing, as it affects the quality and durability of the final product. Good adhesion ensures that the ink or toner does not smudge or fade over time. Factors influencing print adhesion include the type of ink used, the surface texture of the substrate, and environmental conditions like humidity and temperature. Proper preparation of the substrate, such as cleaning or priming, can enhance adhesion and improve the overall print quality.
