Offset Printing Blanket

Offset printing, also known as lithography, is a printing technique that uses a chemically treated blanket to

transfer ink onto the printing surface. The process involves several steps:

1. Plate Making: A metal plate (often copper) is prepared with a chemically treated surface (called the

"plate") using photolithography.

2. Ink Application: Lithographic inks are applied to the treated plate, which selectively attract the ink due

to chemical differences between the treated and untreated areas of the plate.

3. Printing Process: The printing blanket (usually rubber) is rolled over the plate, absorbing the ink. As the

blanket is lifted, it transfers the ink to the printing surface (e.g., paper, metal, or plastic).

Offset Printing Blanket:

- Purpose: To transfer ink from the plate to the substrate.

- Materials: Typically made of rubber or other elastic materials.

- Construction: The blanket may have different textures or patterns depending on the printing needs.

Advantages:

- High-speed production

- Suitable for large-scale printing

- Can print on a wide range of surfaces

Offset printing is widely used in packaging, advertising, and industrial applications. Let me know if you need more details!
