What is Offset Printing?

Offset printing is a popular printing technique that uses a series of metal plates and rollers to transfer ink onto paper or other materials. The process involves transferring ink from a metal plate to a rubber blanket, which then applies the ink to the paper or other surface.

The plates used in offset printing are typically made of aluminum and contain an image of the desired print material. The image is etched into the plate using chemicals or lasers, creating a pattern of raised and recessed areas that correspond to the desired image.

During the printing process, the plate is dampened with water and then coated with ink. The ink adheres to the raised areas of the plate, while the dampened areas repel the ink. The plate is then pressed against a rubber blanket, which transfers the ink onto the paper or other material.

Offset printing is known for its high-quality and consistent results, making it a popular choice for a wide range of printing applications, including books, magazines, brochures, and packaging. It is also capable of producing large quantities of prints at a relatively low cost, making it an efficient choice for large-scale printing projects.
