[0002] A gravure printing press uses an intaglio plate for printing. The image and text areas of the plate are recessed, while the blank areas are flush with the outer diameter of the plate cylinder. During printing, the entire plate cylinder is inked. A doctor blade removes the ink from the blank areas, leaving only the ink on the image and text areas. The paper is then passed over, and the impression cylinder presses the back of the paper, transferring the ink from the recessed areas directly to the paper. Finally, the printed material is stacked or rewound in the paper delivery section.
