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. The developed printing plates have excellent durability without baking.
