Cold Transfer - the process in Sheet-fed Offset printing
Cold Transfer is realised via two conventional printing units in an offset printing press. The first printing unit applies an application-specific adhesive (adhesive printing ink) via an inking unit, an offset printing plate. Depending on requirements, the ink can be applied either partially or over the entire sheet. Fine lines and fonts as well as halftone effects can be transferred, since the properties of offset printing come into play during adhesive application just as they do with a conventional offset printing ink. Via a second printing unit, which is equipped with a special Cold Transfer module and an unwinding and rewinding station, the Cold Transfer product is fed into the printing nip between the blanket cylinder and the impression cylinder and transferred under pressure to the areas of the sheet where the adhesive has been applied.
After the backing material has been removed, the metallised transfer layer remains on the substrate and adheres directly and permanently to the sheet preprinted with the adhesive by means of a special adhesive layer. The substrate is then rewound with the non-transferred areas through the Cold Transfer module. A wide variety of metallic colour effects and shades can be achieved by subsequent inline overprinting of the Cold Transfer product in subsequent printing units or in a separate work step. Coated art paper and folding carton boards with surfaces that are as smooth as possible offer the best conditions for high-quality Cold Transfer applications. In addition, non-absorbent substrates such as PP or PE can also be used.
Advantages
The transfer of finest details, fonts as well as areas and screens are possible in one operation
Inline and offline overprinting processes are possible.
No Hot Stamping clichés are required for cold product transfer.No heat or high pressure is required for the process.
The surface structure of the substrate is retained on both sides, and there is no deformation of the substrate.Very short makeready times and fast roll and job changes.
Fast changeover from Cold Transfer mode to standard printing mode.
Very high production speeds.
Compared to metallised substrates, no opaque white application is necessary for cold product applications. The whiteness of the substrate can be optimally and efficiently utilised by corresponding omission of the Cold Transfer product.Product and cost savings are possible through the use of clocked Cold Transfer modules.
