Lithography: printing

1. The image is washed out with solvent through the gum film, and asphaltum is applied as a grease base. The stone is then sponged with a thin film of water that washes off the gum film and any excess asphaltum.

2. Printing ink is applied to the stone using a hand-roller. The ink adheres to the image areas and is rejected in the non-image areas.

3. The stone is alternately sponged and rolled over with ink until the tonalities of the image are built up to replicate the original drawing.

7. The stone is alternately sponged and re-inked for each new impression until the edition is complete.

8. Once the desired number of prints has been produced, the stone is re-grained (or polished) and used again to apply the next color to an image or create an entirely new one.
