Offset lithography is the most common high volume commercial printing technology. In offset printing, the desired print image is burned onto a plate and is then transferred (or offset) from the plate to a rubber blanket, and then to the printing surface. 

Advantages of Offset

• High image quality.
• Works on a wide range of printing surfaces.
• The unit cost goes down as the quantity goes up.
• Quality and cost-effectiveness in high volume jobs. 
• Many modern offset presses use computer-to-plate systems as opposed to the older computer-to-film work flows, further increasing quality.
