Planographic Printing

In this method of printing the ink is neither pressed down into the paper nor raised above its surface, but lies exclusively on the plane of the paper. This means that with planographic printing the printed and non-printed areas on the surface of the print exist on the same plane. Planographic techniques include: lithography, serigraphy, pochoir, monoprints, monotypes, screenprints, digital prints, and counterproofs
