Offset label printing

Offset printing is a technology in which the printing areas and recesses are practically on the same plane. Before applying the ink, the printing plates are coated with a wetting solution. The printing areas, which are divided into oleophilic (which absorb ink) and hydrophilic (which absorb water), produce selective printing. An intermediate offset cylinder with a mounted rubber cloth helps transfer ink from the printing plate onto the paper.

Offset label printing is carried out using special plates. Offset printing plates are produced on extremely thin aluminum or zinc plates using photomechanical, diffusion, electrophotographic or other methods, including lasers.

The advantages of offset label printing include the fact that all processes can be highly standardized, printing plates are cost-effective, ink use is confined to a minimum, and that bitmap transitions from 0 to 100% can be made.
