Once the plate is prepared, it is mounted onto a cylinder on a printing press The plate is then dampened with water, which adheres to the non-image areas and repels the ink The ink is applied to the plate by rollers, which only adheres to the image areas As the plate cylinder rotates, the inked image is transferred onto a rubber blanket, which in turn transfers it onto the paper or other print material.
