Print processes

Rotary printing

Image printing plates are wrapped around a cylinder. Automated print process, can be sheet fed or on roll.

Three main types of rotary printing

Offset lithography (Litho)

Rotogravure (Gravure)

Flexography (Flexo)

Litho (Planographic)

Etched aluminium plates are wrapped arounda cylinder transfer ink to an 'offset' rubber blanket roller and then to print surface sheet fed or web fed

Web 'Offset' machine

Most machines are incredibly fast and run rolls of material as opposed to sheet fed. Often have finishing and folding built into the machine

Gravure (Intaglio)

Copper plates with mirror image, transfer ink directly to print surface, usually on rolls. Plates are more durable, good for long print runs. Prints such as flooring, newspaper and magazines

Flexo (Relif)

A positive, mirror image rubber polymer plate, on a cylinder, transfers 'Sticky' ink directly to print surface usually roll fed

Flexo plate, rubbery silicone feel with the image raised 2-4mm

Used for packaging like chocolate wrappers, bag packaging

Digital printing

The production of images by translating the digital code direct from a computer to a material without an intermediate physical process

Suited to short run or specials on a range of print media from paper to metal

Pad printing

A printing process that can transfer a 2D image onto a 3D object.
