Abbreviation for Work and Back, a printing method in which the front and back of pages are assembled on two different plates. The printing is done by turning the page over after the first side is printed and using the same gripper and side guides. This technique is also called sheetwise.
Abbreviation for Work and Turn, a printing method in which both sides of a sheet can be printed using a single plate. The paper is turned over after the first side is printed, using the same edge of the first printing as the gripper edge for the second printing. Different side guides are used for each pass.
A term given to the occurrence of plate deterioration of the image area during the printing process. It usually occurs on long runs.
The procedure of cleaning a particular ink from all of the printing elements (rollers, plate, ink fountain etc.) of a press.

Abbreviation for Windows Color System, the color management engine that is included in Microsoft operating systems such as Vista and Windows 7. Its goal is to achieve color consistency across various software and hardware solutions, including cameras, monitors, printers and scanners.
A roll of paper stock used in web or rotary printing.
A tear in a web roll during the printing process.
The deformation of the paper printed on a web press.The physical deformation occurs as the paper absorbs ink and water and is accelerated with pressure and tension. Factors contributing to web growth include: the type of press, press configuration, paper stock, humidity, ink coverage and the conditions of the blankets. Web width changes also happen with wide web flexo and gravure. With flexo and gravure presses that have interunit hot air dryers, the web width will shrink as it goes through the press because of the moisture loss of the paper due to the hot air drying. Web growth in the web width direction was called fan out. Fan out rollers or spiral taped rollers help minimize this problem. Some web presses used a Fife system or series of “S” rollers to minimize the problem.
A printing lithographic process that prints on paper from a continuous roll and delivers onto another roll or as folded signatures.
A printing press that prints on rolls of paper. This type of press is typically used to print newspapers, magazines, large catalogues or other jobs where the number of impressions exceeds 25,000 copies. Because web presses ‘pull’ a continuous piece of paper through the press, lighter weight papers can be used. Many web presses have the ability to do folding for complicated direct mailers and brochures.
The term given to the tension or pull exerted by the web press on the web roll.
A system or process that allows customers to order and possibly create & edit a printed publication using an internet connection.
