GB/T9851 "Printing Technology Terms" is divided into 7 parts. This part is the 5th part of GB/T9851. This part replaces GB/T9851.6-1990 "Printing Technology Terms Part 6: Gravure Printing Terms". This part of GB/T9851 specifies the professional terms within the scope of gravure printing to ensure the correct application of professional concepts in production, teaching and academic activities. This part is applicable to the use of the printing industry and its related professions in the compilation of standards, publishing, teaching, scientific research, production and domestic and foreign technical exchanges. Compared with GB/T9851.6-1990, this part is mainly modified as follows: --- According to the development of technology, the entries of drum polishing, sleeve printing plate, gravure engraving machine, and failure are added. --- Some outdated entries are deleted, such as: gravure screen, milky white copy negative, sun screen, carbon paper sensitization, sun positive image, corrosion failure. Delete too small entries, such as: ink scraper stroke, ink scraper angle. ---Modification: some entries are merged, such as single-bath etching and multi-bath etching, and they are combined into roller etching.
