What are the main types of printing presses?
Printing is primarily divided into three main categories depending on whether the image surface that gets inked is indented (eg, engraving), flat (eg, lithography), or raised (eg, letterpress). That is, with engraving, the image gets cut into the material (eg, copper); lithography, the image is painted on a flat stone surface; and letterpress, the image is raised metal, linoleum, or wood.
