lithograph

Imagine an artist wanting to make several copies of a drawing before photocopiers or digital printers existed. That is where lithography comes in. The word "lithograph" can mean both a type of printing process and the print made with it. It works because oil and water do not mix. The artist draws on a smooth surface, traditionally stone, with a greasy material. When the surface is damp, the drawn parts hold the ink, while the blank parts push it away. The image is then pressed onto paper to make a print. Many vintage posters, book illustrations, and art prints were made this way.

Lithography is a printing process that depends on the way oil and water resist each other. The word comes from the Greek "lithos" (stone) and "graphein" (to write). In the original method, an artist drew directly on a smooth limestone surface with a greasy crayon, pencil, or liquid drawing material. Those drawn areas would later accept ink, while the rest of the surface would not.

The surface is then dampened with water, which stays on the non-greasy parts, and rolled with ink. The ink sticks to the drawn image and is rejected by the wet blank areas. Paper is pressed against the surface, transferring the image. Although the process began with stone, later versions often used metal plates, especially in commercial printing.

The word "lithograph" can refer to the process itself, but it is also commonly used for the finished print. In art, lithographs are valued for their soft shading, clear lines, and wide range of tones. The method became especially important in the 19th and early 20th centuries for posters, illustrations, sheet music covers, and fine-art prints.

You will often see the term in art history and museum labels. Artists such as Toulouse-Lautrec and Daumier helped make the technique famous through posters and illustrated prints. So if you come across a vintage print with rich tones and a drawn, handmade feel, it may well be a lithograph.
