WURZBURG, GERMANY—December 1, 2014—On Nov. 29, 1814, 360 years after Gutenberg invented the hand press, a new steam-powered double-cylinder printing press from Friedrich Koenig and Andreas Bauer was ...

Scientists from the Fraunhofer ISE built a bifacial heterojunction solar cell with a power conversion efficiency of 21.7% via rotary screen printing. They used a machine that is able to achieve a ...

How does a typical printing machine work? Today's most common printing machines use a flexographic process. Flexography is a direct rotary printing method that uses a raised image surface to print on ...

MR. BENNETT describes in clear and simple language every step of the process of the making of photogravure prints by the screen plate process, leaving the original dust-grain process with little more ...
