| 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. |
