![]() Imposition has been a requirement since the earliest days of printing. A little copy is then created, and this can help paginate the product. This is made by folding several sheets of paper in the way the press will print and fold the product. To understand how the pages are related to each other, an imposition dummy may be used. These fibers must run lengthwise along the fold, which influences the alignment, hence the position, of the pages on the printed sheet. ![]() Paper fiber direction: Many papers have a "grain," reflecting the alignment of the paper fibers.Stitching/binding method: The compositor must understand how the sheets are placed to form the signatures that compose the finished book.Number of pages of the printed product: The compositor must determine how many sheets are to be printed to create a finished book.Format of the product: The size of the finished page determines how many pages can be printed on a single sheet.The arrangement of pages on the printer’s sheet is affected by five different parameters: To achieve this, the printed sheet must be filled as fully as possible. It consists of the arrangement of the printed product’s pages on the printer’s sheet, in order to obtain faster printing, simplify binding and reduce paper waste.Ĭorrect imposition minimizes printing time by maximizing the number of pages per impression, reducing cost of press time and materials. Imposition is one of the fundamental steps in the prepress printing process. ( June 2014) ( Learn how and when to remove this template message) Please see discussion on the linked talk page.
