CY/T 59-2009 "paper printing die-cutting process control and detection method" stipulates the terminology, process basic conditions, process control, mass requirements and inspection methods of paper printing products in the die-cutting process. This standard is applicable to the flat die-cutting (including indentation) of paper and paperboard printing products, and the die-cutting (including indentation) of corrugated fibreboard can also be referred to. By implementing this standard, it is possible to ensure that the printed product meets the expected size, shape and mass requirements during the die-cutting process, improve production efficiency and product mass, and meet the needs of the market and customers.
