| Offset printing is a widely used
printing technique where the inked image is transferred
(or "offset") from a plate first to a rubber
blanket, then to the printing surface. When used in combination
with the lithographic process, which is based on the repulsion
of oil and water, the offset technique employs a flat
(planographic) image carrier on which the image to be
printed obtains ink from ink rollers, while the non-printing
area attracts a film of water, keeping the nonprinting
areas ink-free. |
| |
| The
advantages of offset printing include: |
|
| Consistent
high image quality — sharper and cleaner
than letterpress printing because the rubber blanket conforms
to the texture of the printing surface |
| Usability
on a wide range of printing surfaces — in
addition to smooth paper (e.g., wood, cloth, metal, leather,
rough paper) |
| Quick
and easy production — of printing plates |
| Longer
plate life than on direct litho presses —
because there is no direct contact between the plate and
the printing surface. |
