Print production process

linocut Linocut is a printmaking technique, a variant of woodcut in which a sheet of linoleum is used for the relief surface. A design is cut into the linoleum surface with a sharp knife, V-shaped chisel or gouge, with the raised areas representing a reversal of the parts to show printed. The linoleum sheet is inked with a roller and then impressed onto paper or fabric. The actual printing can be done by hand or with a press.

Gravure Gravure is a printing method in which an image is applied to a printing substrate by use of a metal plate mounted on a cylinder. Unlike other processes, gravure uses a depressed or sunken surface for the desired image. The image to be reproduced is etched into the metal plate, sometimes with the use of a laser . The metal plate is bathed in ink during the process and then wiped clean before application to the substrate. While gravure printing can produce high-quality results rapidly, the costs are significantly higher than other printing methods, including flexography or various forms of digital printing .

lithography Lithography refers to a lithograph print that is made from an image which has been applied to a flat surface. Traditionally this flat surface was a specially prepared lime stone, but today grained aluminium-printing plates and the original stones are used. The process is based on the fact that oil repels water. An image is drawn, painted or photographically applied the stone or plate using a greasy medium. The image will repel water and accept ink. Lithographic inks are oil based

Laser printing Laser printing is an electrostatic digital printing process that rapidly produces high quality text and graphics by passing a laser beam over a charged drum to define a differentially charged image. The drum then selectively collects charged toner and transfers the image to paper, which is then heated to permanently fix the image. As with digital photocopiers and multifunction printers laser printers employ a xerographic printing process, but differ from analog photocopiers in that the image is produced by the direct scanning of the medium across the printer's photoreceptor. Hence, it proves to be a much faster process compared to the latter.

Photocopying Photocopying machines are fairly complicated devices, but the basic principal is pretty simple. At the heart of the process are static electricity, a metal drum, a system of lenses, and dark powder.
