Lithography is a print on which the image is printed from a plastered limestone, even zinc or aluminum plate, can be used. The technology is based on the fact that fat and water repel each other. One uses a stone for each color. The word lithography comes from the Greek words lithos = stone and graphein = to write.
The image is drawn to the stone with special fat crayons or bold bark. Then the stone is coated with arabic rubber, which covers the surfaces that have no image. Excessive crayon and ink are washed away with solvents. The stone is then moistened with water, which does not stick where there is a picture. When rolling the paint on the stone, the paint is repelled out of the water and stuck only where there is an image. Finally, a paper is pressed against the stone in a lithographic press.
