Alroy of Voltera talks about their dual-layer circuit board printer.
In this video, Norm from Tested.com investigates the art of letterpress and relief printing and the machines that makes them. While antique machines like the ones in this video is rare and difficult to get a chance to work with, this video shows the fundamental workings and process of Letterpress printing and relief printing. We get to see the different techniques used to make the print, such as movable type in lead, “job sticks”, “furniture”, carved designs and a modern material called “Polymer plate”. In the end the resulting paper print is stunningly beautiful and a valuable hand crafted piece of art.
