  • Aluminum printing plates and method of making
    Publication number: 20010046645
    Abstract: A method of making improved aluminum printing plates comprising graining the aluminum plates, de-smutting them by treating them with nitric acid solution, then rinsing with hot water, acetating the aluminum plates, and silicating the aluminum plates. The plates are then coated with a photoresist, pattern exposed and developed. The printing plates of the invention have improved characteristics; they have excellent adhesion of the resist in image areas, and ink repellency in non-image areas.
