How did Alphonse Mucha make his posters?

Alphonse Mucha made his posters using a printmaking technique known as lithography. The process involves first using a greasy crayon or a black wash called tusche to draw an image onto a stone. Then, the artist treats the stone with chemicals before finally applying ink and pressing the stone against paper to produce an image. Explore a collection of Alphonse Mucha art on 1stDibs.
