Flexo printing requires rubber plates that transmit to the media (paper or plastic) the link present in the elevated regions of the plate.
The traditional flexographic media comprises four kinds of rollers; a fountain roller, and an anilox roller, and the plate - tube, and the impression cylinder.
The fountain roller provides ink in an ink pan into a ceramic or steel ink-metering "anilox" roller then to the plate canister. The cylinder applies the strain needed to move the ink from the plate into the substrate.
In flexography, the anilox roller can move a uniform depth of ink into the printing plate. Every anilox roller contains engraved cells which are the element that decides how much ink will be transported to the plate. An optional blade scratches the anilox roller top to ensure the ink delivered into the printing plate is homogeneous.
Each colour or coating is put at every print section. Drying units help guarantee that every colour of ink is completely dried. Dryers utilize warm air or infrared or ultraviolet lighting based upon the curing that the ink requires.
Various versions of wide-web presses are designed to deal with materials which thickness ranges from 20 microns to around 5 millimetres.
Narrow-web presses 200-500mm wide is used to publish shorter packaging runs such as bottle wraps and single-serve packs, adhesive labels, butt-cut labels, and shrink sleeves.
EB (electronic beam) curing systems provide energy straight to the inks from the shape of active electrons and do not demand photoinitiators as UV-curable inks perform. Always interface with the packaging supplier to understand if the inks and curing methods are safe for food products!

From the packaging globe, laminates are multi-layered substances made from various mixtures of substrates, including aluminium foil, film, and paper. Laminates supply the barrier layers, which flexible packages might have to keep the contents protected from moisture, air or chemical contamination.
