A double-sided printing process for the production of paper products

Abstract

The invention provides a double-sided printing process for the production of paper products, comprising the following steps: 1) designing the printing pattern on the front and back of the paper; 2) installing the base paper roll to be printed on the paper feeding roller of the printing device; 3 ) Blow out hot air on both sides of the base paper roll to be printed to perform preliminary cleaning; 4) Print one side of the base paper through the double-sided printing unit of the printing device; 5) Blow out hot air on the printed side of the base paper to print the pattern Drying; 6) Print the same pattern on the other side of the base paper through the same double-sided printing assembly; 7) Blow hot air on the other side of the base paper after printing to dry the printed pattern; 8) Pass the winding roller Finished printing can be obtained by rewinding the dried printing paper. The invention can print the same content on both sides of the paper through one device, which saves cost, improves efficiency and reduces waste of resources.

Description

technical field [0001] The invention relates to a double-sided printing process for producing paper products, belonging to the technical field of paper product printing. Background technique [0002] At present, the web printing machine has the advantages of fast printing speed and high production efficiency, so it is more and more widely used in fields that require large-volume printing. [0003] When the existing web printing machine prints the same content on both sides, it is necessary to use two printing machines. The front and back are turned over, and the second printing machine is used to print the back of the web, which requires two printing machines for the front and the back, and the equipment investment is expensive, especially when only one-sided printing is required, one of which is The equipment will be in an empty state, resulting in waste of equipment resources, and the two equipments occupy a large area and have low practicability. [0004] In addition, s...

[0003] When the existing web printing machine prints the same content on both sides, it is necessary to use two printing machines. The front and back are turned over, and the second printing machine is used to print the back of the web, which requires two printing machines for the front and the back, and the equipment investment is expensive, especially when only one-sided printing is required, one of which is The equipment will be in an empty state, resulting in a waste of equipment resources, and the two equipments occupy a large area and have low practicability

[0004] In addition, some existing printing equipment can realize double-sided printing on one printing machine, but the equipment is complicated and the manufacturing cost is high
