Offset Printing
What is Offset Printing
Offset printing is a widely used printing technique where ink is transferred (or “offset”) from a printing plate to a rubber blanket and then onto the printing surface. It is ideal for producing high-quality, large-volume prints on a variety of materials, such as paper, cardboard, and plastics. Offset printing is known for its sharp details, consistent color quality, and cost-effectiveness for bulk printing.
Procedure of Offset Printing
The offset printing process involves several key steps:
Design Preparation
A digital design or artwork is created and separated into color plates (CMYK: Cyan, Magenta, Yellow, and Black).
Plate Creation
Metal plates are prepared for each color. These plates carry the image or text to be printed.
Ink Transfer
Ink is applied to the printing plates and then transferred (offset) to a rubber blanket. The blanket ensures smooth and even ink distribution.
Printing Process
The rubber blanket transfers the ink onto the printing surface (e.g., paper or other material) with precision and clarity.
Drying and Finishing
Once the ink is transferred, the print is dried and may go through finishing processes such as cutting, folding, binding, or lamination.
