Gravure printing requires a printing press.

Four-colour printing on a two-colour flatbed press requires that a sheet be passed through the press twice.

A sheet-fed rotary press and a web-fed rotary press, which is fed a continuous length of paper unwinding from a roll, can print four colours in a single pass of the paper, depending on design.

The steam powered rotary printing press was invented in 1843 by Richard Hoe. Its innovation was the use of rollers instead of a flat bed and it greatly increased the speed of printing.

(example: approx. copies per hour - manual flatbed press 500, steam operated flatbed press 2,000, steam rotary press 20,000)

The increased quantity being printed reduced the unit cost and this allowed the owners to reduce the price of newspapers while continuing to make profits.

Johannes Gutenberg was known for inventing the printing press around the year of 1450. He was also known for the Gutenberg bible later created with his own printing press.
