Hydrographic printing is a process that applies layers of color to a surface using water. The colors are typically applied to a substrate such as vinyl, plastic, metal, or glass. The advantages of hydrographic printing are that it is durable and can be used on a variety of materials. The disadvantages of hydrographic printing are that the process can be expensive and the colors may not be as bright as other methods. Hydrographic printing is most commonly used for automotive parts, but it can also be used for other applications such as signs, labels, and packaging.
