Web18 feb. 2024 · In a nutshell, a chromolithograph is a type of colored lithograph. Lithography begins by: Creating an image on a flat stone or metal plate using a greasy substance. The plate is then treated with a chemical solution, which attracts ink to the greasy areas and repels it from the non-greasy areas. The ink is transferred to the paper using a press ... Lithography (from Ancient Greek λίθος, lithos 'stone', and γράφειν, graphein 'to write') is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the … Meer weergeven Lithography uses simple chemical processes to create an image. For instance, the positive part of an image is a water-repelling ("hydrophobic") substance, while the negative image would be water-retaining … Meer weergeven • About Lithography • Twyman, Michael.
