Lithography is a printmaking process based on the immiscibility of oil and water. It was invented in 1796 by the German author and actor Alois Senefelder as a method for reproducing text and images efficiently. This process involves creating an image on a flat stone or metal plate, typically limestone or aluminum, using oil-based substances. The surface is then treated with a chemical solution that ensures the image areas repel water but attract ink, while the non-image areas do the opposite.

In traditional lithography, artists draw directly on the prepared surface with greasy pencils, crayons, or inks. Once the image is finalized, the plate is inked, and the surface is pressed onto paper to produce the print. Modern lithography has evolved to include offset lithography, where the image is transferred from a plate to a rubber blanket before printing onto paper, enabling high-volume printing with consistent quality.

Lithography is widely used in commercial printing, fine art, and illustration. Its ability to produce detailed and nuanced images has made it a popular medium among artists since the 19th century. Notable lithographers include Henri de Toulouse-Lautrec and Alphonse Mucha, who utilized the technique for posters and artworks.

Innovations continue in lithographic methods, including digital lithography and chemographic processes, which allow for greater flexibility and efficiency. Despite technological advances, traditional lithography remains valued for its artistic qualities and capacity for fine detail. It stands as an important historical and contemporary printmaking method contributing significantly to the arts and publishing industries.
