The plate is then etched simply by washing the plate with water, revealing the original image on the plate. The image is transferred to the plate by exposure to UV light. The transparency is sandwiched with a steel plate that has a UV light-sensitive emulsion, known as a photopolymer plate. It first involves making a transparency from a photograph. A printing press is a mechanical device for applying pressure to an inked surface resting upon a print medium (such as paper or cloth), thereby transferring the ink.It marked a dramatic improvement on earlier printing methods in which the cloth, paper or other medium was brushed or rubbed repeatedly to achieve the transfer of ink, and accelerated the process. Reducing the size and weight of the printing press and using precision machining by the Kughler Company in Ballard, the Halfwood Press performs like presses weighing hundreds of. The term "intaglio" is an Italian word meaning "carved" or "recesses." The intaglio process provides the opportunity for gradations in tone in the final print.Ī modern method of creating an etched plate from which to print intaglios is used. In 2004, Seattle printmaker Bill Ritchie designed a stylish miniature version of the professionals’ fine art printing presses used worldwide for printing etchings, engravings, linocuts, and lithographs. Intaglio is the opposite of relief printing such as woodcuts which rely on the surface ink. Ink is pressed into the recesses of the etched metal plate, and the plate is then pressed onto dampened paper using a printing press. The intaglio presses first print the back of the currency sheets in green ink. All forms of intaglio printmaking rely on making an image based on ink being drawn from the etched or "sunken" areas of a plate or other media rather than from the surface. On this press, the face and back of the sheet is printed at the same time. The upper pressure drum may be raised 1.25' above the bed for relief printing. Micrometer pressure dials are supplied with each press to allow consistent pressure application and repeatability. The rubber cylinder gives great flexibility, permitting printing on wood, cloth, metal, leather, and rough paper. Printing pressure is applied by lowering the upper pressure drum onto the press bed using the pressure adjusting screws. Intaglio printmaking has been around in one form or another for almost 700 years. offset printing, also called offset lithography, or litho-offset, in commercial printing, widely used printing technique in which the inked image on a printing plate is printed on a rubber cylinder and then transferred (i.e., offset) to paper or other material.
