Browsing: Lithography

Lithography is a printing process that involves creating images or text on a flat surface, typically a stone or metal plate, and using the principle that oil and water do not mix. Invented in the late 18th century by Alois Senefelder, lithography allows for the mass production of high-quality prints. The process begins by drawing an image with a greasy substance onto the plate. The plate is then treated with a chemical solution that ensures that the drawn areas attract ink, while the non-drawn areas repel it. When the plate is pressed against paper, the inked image is transferred, creating a print. Lithography has been widely used in artistic printmaking, as well as in commercial printing for books, posters, and packaging. In the modern era, the term “lithography” has also come to refer to a process used in semiconductor manufacturing, where patterns are transferred onto silicon wafers to create integrated circuits.
