			Lithography The greasy areas, which represent the printing image, attract and hold the ink. Because of the mutually repellent nature of grease and water, the ink does not adhere to those areas covered with a film of water. After inking, the stone, placed upward on the bed of the press, is covered with a sheet of dampened paper and run through the press. The printed image reverses the composition as drawn on the stone. In colour lithography a different stone is prepared for each colour and printed successively in register. Since they are printed from a flat surface, the lines in a lithograph are neither raised, as in intaglio processes, nor pressed into the paper, as in relief processes.                                                                     Begin demonstration Previous Page  3/3
