Off-Set Printing Process
Process Description
Off-set printing process is where the ink image is transferred (offset) from a plate to a rubber blanket, then to the printing surface. When used in combination with the lithographic process, which is based on the principle of oil and water repulsion, to make an image. Firstly, is to supply water to the non-image areas of the printing plate, to protect the images from being stained with ink, then during printing, provide ink supply to the image area of the printed plate. Finally, the transfer of ink to the canvas and then a rubber roller is rolled over it, leaving an impression of the desired images on the canvas. Lithography is an indirect printing.
