18 인쇄 및 기록매체 복제업

설명

This division includes printing of products (for example, newspapers, books, periodicals, business forms and greeting cards), printing on T-shirts and other types of material, and associated support activities (for example, bookbinding, plate-making services, data imaging). The support activities included here are an integral part of the printing industry, and a product (a printing plate, a bound book, or a computer disk or file) that is an integral part of the printing industry is almost always provided by these operations. The ownership of the input material is irrelevant to the classification of printing and reproduction of recorded media activities. Division 18 covers explicitly the processing activities. Processes used in printing include a variety of methods for transferring an image from a plate, screen or computer file to a medium (for example, paper, plastics, metal, textile articles, wood). The most prominent of these methods entails the transfer of the image from a plate or screen to the medium through lithographic, gravure, screen or flexographic printing. Often a computer file is used to directly drive the printing mechanism to create the image or electrostatic and other types of equipment (digital or non-impact printing). Though printing and publishing can be carried out by the same unit (for example, a newspaper), it is less and less the case that these distinct activities are carried out in the same physical location.
