Lithographic printing is a popular printing technique that uses a flat surface to transfer images and text onto paper. It is based on the principle that oil and water do not mix. In this process, an image is drawn on a stone or metal plate with a greasy substance. The plate is then treated with water and ink, allowing the ink to adhere only to the greasy areas, which represent the image. This method is widely used for producing high-quality prints, such as posters, books, and packaging. Lithography has evolved over time, leading to modern variations like offset printing, which uses a rubber blanket to transfer the image, enhancing efficiency and print quality.
