Description

Technical Field

[0001] The utility model relates to the technical field of proofing machines, in particular to a label proofing machine. Background Art

[0002] At present, sample proofing in the entire label printing industry is basically divided into two types: digital proofing and large-scale machine proofing. Digital proofing can only help brand owners confirm the design direction in the early stage of the product, but digital proofing is not the same printing method as the actual bulk product, and there is a big difference with the final product. Therefore, it cannot be used as a proof for the final signing.

[0003] 1. The actual large-scale machine proofing costs thousands of yuan for dozens of signed samples, and the proofing rollers are basically set on large machines of several hundred meters. A group of large-diameter rollers need to be equipped with gear transmission, which increases the cost of label proofing;

[0004] 2. The current rollers in foreign countries have a notch on one side. Therefore, in order to stably cold-foil the labels, it is necessary to use a separate device for cold-foil after label proofing, which increases the cost of cold-foil.

[0005] 3. The current proofing machines abroad are basically online plate-mounting machines. It takes three to five minutes to replace a printing plate, which increases the labor of the staff and greatly reduces the efficiency of label proofing;

[0006] 4. The current proofing machines abroad clean the anilox roller online when changing colors, which increases the labor of the staff and greatly reduces the efficiency of label proofing;

[0007] 5. The anilox rollers of current proofing machines abroad are all forward scrapers, which leads to unstable ink transfer. Utility Model Content
