Carborundum etching (sometimes called carbograph printing) was invented in the mid-20th century by American artists who worked for the WPA. [17] In this technique, a metal plate is first covered with silicon carbide grit and run through an etching press; then a design is drawn on the roughened plate using an acid-resistant medium. After ...
Conrad Machine Co. is an independent manufacturer of etching and lithography presses, which it first began producing in 1956.The company was founded in 1945 by brothers Earl and Robert Conrad, and they offered general engineering services as well as their own products.
Much greater pressure is then needed to force the paper into the channels containing the ink, so a high-pressure press is normally needed. Intaglio techniques include engraving, etching, and drypoint. In the planographic family of printing, the entire surface of the matrix is flat, and some areas are treated to create the print image.

Although glass is unaffected by compression in the printing press, it will break under tension. For that reason, vitreographs are always printed on an etching press, whose rigid bed will support the glass plate firmly. [6] In addition, the press bed must be level and working conditions in the print shop immaculate.
In intaglio printing, the lines to be printed are cut into a metal (e.g. copper) plate by means either of a cutting tool called a burin, held in the hand – in which case the process is called engraving; or through the corrosive action of acid – in which case the process is known as etching.
A larger burr, formed by a steep angle of the tool, will hold a lot of ink, producing a characteristically soft, dense line that differentiates drypoint from other intaglio methods such as etching or engraving which produce a smooth, hard-edged line. The size or characteristics of the burr usually depend not on how much pressure is applied, but ...
