Offset printing is the most commonly used high-quality and cost-effective printing method in the publishing and printing industry today. The name “offset” comes from the process of transferring ink first onto a plate, then to a rubber blanket, and finally onto paper. This indirect printing technique ensures sharper, cleaner, and more durable print results.
How Does Offset Printing Work?
- Design Preparation: The content to be printed is prepared digitally, typically using CMYK color codes.
- Plate Creation: Separate metal plates (usually aluminum) are created for each color.
- Ink Transfer: The ink is transferred from the plate to a rubber blanket.
- Printing on Paper: The ink is then applied from the blanket onto the paper. This system enables printing without direct contact between the plate and the paper surface.
