PHOTOGRAVURE involves intaglio, or engraving an image below the surface of the non-image area. The process works like this: a printing substrate mounted on a copper cylinder is immersed in ink, which can create tiny cells as the images are screened. As the image carrier cylinder rotates, ink fills the tiny cells, covering the surface. As the surface is wiped with a blade, the non-image area is clean while ink remains in the cells.
