Diagram of rotogravure process. Rotogravure (or gravure for short) is a type of intaglio printing process, which involves engraving the image onto an image carrier. In gravure printing, the image is engraved onto a cylinder because, like offset printing and flexography, it uses a rotary printing press.
More popular modern and contemporary methods include etching, pantograph engraving, and engraving using electric or air-powered rotary tools. In the US, one-cent coins are most commonly used in these vending machines, as they are thin, easy to emboss, and are the smallest denomination of US money (most machines charge US$ 1.00 in addition to ...
The rotary printing press uses impressions curved around a cylinder to print on long continuous rolls of paper or other substrates. Rotary drum printing was later significantly improved by William Bullock. There are multiple types of rotary printing press technologies that are still used today: sheetfed offset, rotogravure, and flexographic ...
Flexography (often abbreviated to flexo) is a form of printing process which utilizes a flexible relief plate. It is essentially a modern version of letterpress, evolved with high speed rotary functionality, which can be used for printing on almost any type of substrate, including plastic, metallic films, cellophane, and paper.
Rotary letterpress machines are still used on a wide scale for printing self-adhesive and non-self-adhesive labels, tube laminate, cup stock, etc. The printing quality achieved by a modern letterpress machine with UV curing is on par with flexo presses. It is more convenient and user friendly than a flexo press.
The rotary press itself is an evolution of the cylinder press, also patented by William Nicholson, invented by Beaucher of France in the 1780s and by Friedrich Koenig in the early 19th century. [ 1 ] [ 2 ] Rotary drum printing was invented by Josiah Warren in 1832, [ 3 ] whose design was later imitated by Richard March Hoe in 1843. [ 4 ]
