Similar to wet offset, but requires a coarser screen, normally 100 to 120 lines per inch. Uses a printing plate with a raised surface. Produces printing quality higher than flexography but lower than wet offset.
A printing method where the areas to be inked are higher than the non-printing areas. The inked areas are then placed in contact with a rubber surface which in turn transfers the ink to the material to be printed. This process eliminates the use of water as required in the lithographic process. A similar technique is used with rubber stamps. Other terms: indirect letterpress; letterset; relief offset. See also: letterpress.
