How Does An Offset Plate Work?
During the offset printing process, the ink rollers on the printing press transfer from the image file directly onto a printing plate. Once plated, the image areas are ink receptive and water repellant, and the non-image areas are water receptive and ink repellant. This ensures that the non-image area remains ink free. From the plate, the image is transferred onto a flexible rubber sheet on the press. As the paper passes through the press, between the rubber sheet and the impression cylinder, the image is then transferred onto the paper. This printing process is called "offset" because the ink is offset to the rubber blanket and then to the paper.
FAQ
1.What is a plate in offset printing?
Offset printing plates are what transfer an image from the ink supply to the paper. They are usually made from paper, rubber, plastic, or metal depending on the printing process. Printing plates have an image that is burned onto them. This image will transfer the ink to the paper.
2.Why is the term OFFSET used when referring to these printing plates?
The reason that the term "offset" is used is because the plate will run against another large cylinder and press the image onto it before it presses onto the paper. This is where the term offset comes from because the plate doesn't directly touch the paper. It offsets onto another rubber-coated cylinder before touching the paper.
