Lithography
Lithography is a printmaking process that transfers an image from a flat stone or plate to paper. The resulting print is a lithograph. It differs from woodcut, which prints from a raised surface, and etching, where ink is held in recessed lines.
How it works
The artist draws with greasy crayon or tusche on a prepared surface, traditionally limestone. Metal plates may also be used. Following treatment, the surface is dampened and rolled with oily ink. Water protects the areas without an image, while ink adheres to the drawing. Paper is pressed against the surface. The process can preserve drawn lines and soft tonal transitions.
What can be checked?
A drawn appearance is a clue, not proof of technique. Artist lithographs, reproductions and other prints may look similar in photographs. Compare the sheet with documented work details, its signature, paper and any workshop information. A written signature alone does not establish authenticity.
Editions and condition
A marking such as 12/75 normally identifies the impression and stated edition size, not necessarily printing order. Check fading, stains, tears and discolouration beside the mount. Avoid direct sunlight and damp conditions. Suitable acid-free mounting materials and separation from the glazing help protect the paper.
