A commonly used printing technique in which the inked image is transferred from a plate 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 water-based film (called "fountain solution"), keeping the non-printing areas ink-free.
Opaque white ink can create a unique print effect — it is a non-transparent ink which does not let any of the base color show though. The more hits of white used, the more it stands out from the background. White ink can be used alone, or as the base to print color on top, which allows full color imagery to be printed on dark colored paper.
