1 Scope

GB/T 25677-2010 is the Chinese national standard on printing machinery - web offset, in the field of image technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 23 December 2010 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 July 2011. Classification: ICS 37.100.10, CCS J87. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the web offset printing press (not including commercial web offset printing press) terms and definitions, basic parameters, requirements, Test methods, inspection rules and signs, packaging, transportation and storage. This standard applies to monochrome and multi-color (simplex printing color calculation) web offset printing press. This standard does not apply to commercial web offset presses.
