The ANSI document was circulated for ISO approval
17、as a fast-track document at the request of the 1989 plenary meeting of ISO/TC 130 and subsequent to its approval was restructured to be in accordance with part 3 of the IEC/ISO Directives. The IT8 document itself resulted from the joint efforts of an international industry group that included partic

That group, initially identified as the DDES (Digital Data Exchange Standards) Committee, later became the founders of the ANSI IT8 (Image Technology) accredited standards committee which is responsible for electronic data exchange
19、standards in graphic arts prepress. 1 Scope This International Standard specifies a format for magnetic tape that will enable colour picture data transfer between colour electronic prepress systems manufactured by different vendors. 2 Conformance A DDES implementation shall be in conformance with th
