Some standard content:
GB/T4313--2002
The differences between this version and G3/4313-1995 are as follows: This standard makes adjustments to the requirements of the extreme rolling tolerance of ribbon length, thickness, base warp and weft density, and seam breaking strength: the provisions of ribbon oil accumulation are cancelled; two types of endless ribbons are added: with and without joints; the print fastness is changed to print UV resistance; the print clarity is changed to print grayscale; the inspection rules are changed to quality assessment procedures, and specific provisions are made. This standard will replace B/F4313-1995 from the date of implementation. This standard is proposed by the Ministry of Information Industry of the People's Republic of China. This standard is approved by the China Electronics Technology Standardization Institute. The drafting units of this standard are: China Electronics Technology Standardization Institute, Yequan Electronics (Shenzhen) Co., Ltd., and Tianwei Printer Consumables Manufacturing Factory.
