printing: Relief Printing
The story of the invention of printing and of its early days is told in the article type . In the 15th cent. the art spread, directly and indirectly, from Mainz to many parts of Europe. It was brought to England in 1476 by William Caxton; to the New World in 1539 by Juan Pablos, who set up his press in Mexico City.
The first papermaking machine producing a continuous roll of paper and capable of delivering sheets in specific sizes—the Fourdrinier machine—was installed in London in 1803. Steam power was successfully applied to the printing press in 1810 by Friedrich Koenig, a German. The invention did not improve the quality of the product but greatly increased the output of the machine. In Koenig's press, the type bed remained flat as in hand presses, but the paper was pressed on the type by a cylinder. The Adams power press was invented by an American, Isaac Adams, in 1827.
In 1846 and 1847, Richard March Hoe designed a rotary press in which stereotype plates were for the first time arranged in a true cylinder. In 1866 a press known later as the Walter press was patented in England; in this press the printing surfaces were not types but stereotype plates curved to form parts of cylinders. The invention of ways of making paper in sheets of any desired length, so that paper could be fed to cylinder presses from rolls, assisted in increasing the speed of printing. Machines for folding newspapers were incorporated with the power cylinder press.
