the anti-counterfeiting effect of printing machine is better. printing machine's secret anti-counterfeiting is one of the main aspects of product anti-counterfeiting. this is achieved through trademarks. printing machine provides the necessary means for it. printing machine is easy to implement secret anti-counterfeiting when engraving. the depth of the pit determines the thickness and brightness of the printing. the imitator can easily imitate the size of the graphics and text and the thickness of the line, but it is difficult to copy the same thick and light level (ie the same deep puddle). this is the main reason why securities must be intaglio for a long time.
the less printing on the printing machine, the better the anti-counterfeiting effect. due to the long cycle and high cost of hand-carved gravure, the printing volume per hour of the printing machine is relatively high. the purpose of counterfeiters is mainly for economic benefits, unwilling to take risks when unprofitable or unprofitable, so it can be said that small batches of gravure printing the anti-counterfeiting effect may be better than mass gravure printing.
