Offset printing

Offset printing is also called lithography.

This technology involves the transfer of images (text and art) from one material to another using printing plates. Offset is the highest quality printing that is low in cost but wide in scope. For example, you can use offset printing to create advertisements, brochures, or packaging on a high-quality sheet-fed machine.

The table below compares offset and digital printing.
