Jane Dickinson's stairwells illustrates what printmaking process?

Jane Dickinson's stairwells illustrate the printmaking process of lithography. This technique involves creating images on a flat stone or metal plate using a greasy medium, which is then treated to attract ink only to the drawn areas. The resulting prints often showcase rich textures and detailed imagery, characteristic of Dickinson's exploration of architectural spaces. Her work highlights the interplay between printmaking and the physicality of the environments she represents.
