printers

Lithography (Litho) PLANOGRAPHIC

Etched aluminium plates on a cylinder transfer ink to an ‘offset’ rubber blanket roller and then to print surface.

Sheet fed or Web fed.

Rotogravure (Gravure) INTAGLIO

Copper plates (with mirror image) transfer ink directly to print surface, usually rolls. Advantage, plates are more durable and so are good for long print runs. Sheet fed or Web fed.

Flexography (Flexo) RELIF

A positive, mirror image rubber polymer plate, on a cylinder, transfer ink directly to print surface. Usually roll feed.
