Method for selecting defective die-cut surface paper in packaging box processing technology

Abstract

The invention discloses a method for selecting defective die-cut surface paper in the packaging box processing technology. The method includes operation steps that 1, a detecting line is printed: when in a printing plate making process for the surface paper, besides normal pattern plate making, detecting lines or detecting patterns are printed at positions, close to cutter lines, of paper required to be die-cut off during plate making or imposition, 2, die-cutting of the surface paper is realized: the surface paper printed with the detecting lines or the detecting patterns is subjected to die-cutting forming on a die cutting machine, 3, qualified products are selected: after the die-cut surface paper is stacked to form a pile, various corresponding side surfaces, which are printed with the detecting lines or the detecting patterns, of the surface paper are checked to see whether printing marks are formed on the side surfaces or not, if the printing marks are formed on the side surfaces of the surface paper, the surface paper is a detective product, and the surface paper is a qualified product when various corresponding edges of the surface paper do not have the printing marks, and4, the surface paper is mounted: the die-cut surface paper is used in a working procedure for mounting the surface paper on a packaging box. The method has the advantages that defective goods of packaging boxes in the technology can be effectively reduced, production raw materials are saved, and processing procedures of the packaging boxes are decreased.

Description

technical field [0001] The invention relates to a printing technology, in particular to a method for selecting unqualified die-cut surface paper in the packaging box processing process, which can select unqualified die-cut surface paper before pasting in the packaging box processing process. Background technique [0002] In recent years, with the improvement of people's requirements for the appearance and quality of commodity packaging, printing technology and packaging technology have made great progress, and post-press processing technology has achieved vigorous development. The production of packaging boxes of different materials requires processing of surface printing paper, die-cutting, lining paper, forming and mounting paper, etc. in addition to processing the outside of the box. The quality of each process directly affects the quality of the final product, so each process is very important. At present, for the sake of beauty, different colors or patterns are often p...

Problems solved by technology

At present, for the sake of beauty, different colors or patterns are often printed on different sides of the packaging box. However, in the die-cutting process, due to various reasons such as the processing of the die-cutting board or the error of the die-cutting board, it is often used during die-cutting. There will be facial paper with misplaced patterns, and the packaging boxes processed with these facial papers are defective products, and the facial paper with misaligned patterns after die-cutting is generally relatively small due to the misalignment, so it is difficult to pick out, so it must be processed after the finished product Only after the defective packaging box can be picked out, not only the face paper of the die-cutting deviation will be discarded, but also the box body and other materials will be wasted, and it will also cause waste in the process
