WebLithography uses the natural repulsion of water and oil to transfer images. Alois Senefelder (1771-1834), a Bavarian playwriter, discovered the lithographic process by accident when searching to reproduce scripts for the actors in his plays. Soon musicians applied the process to duplicate musical scores for orchestras. WebLithography. Lithography uses either zinc and aluminum metal plates or stones for printing. It involves use of a variety of chemicals to make the image ink-receptive and non-image areas receptive to water and ink-repellent. Plate and Stone Preparation. phishing awareness campaign ideas
