Offset printing is called so because the image is not directly printed on the final substrate but onto a rubber blanket. The image is transferred to the blanket from inked rollers and then to the final substrate. Like screen printing, offset prints each color separately. The process is best suited for high volume orders due to the set up time involved.

Why use offset?

It renders a high image quality, excellent color representation and crisp detail. It offers the most variety of printing substrates such as papers, metals, plastics and vinyls, even wood. The unit cost goes down as the quantity goes up.

Sheet fed offset presses offer several advantages. Because individual sheets are fed are fed through, a large number of sheet sizes and format sizes can be run through the same press. In addition, waste sheets can be used for make-ready which is the testing process to ensure a quality print run. This allows for lower cost preparation so that good paper is not wasted while setting up the press for plates and ink.

LEM prints on materials other than paper; primarily on plastics and vinyls. For large runs of tags and labels, offset is the perfect answer.
