Printing anti-counterfeiting process is changing

Plano-convex printing and multi-process printing

That is, using a large press of a letterpress printing machine to print large-area solid color patches with even inked strengths, and printing four-color continuous printing to compensate for complex lines with lithographic printing presses, or using concave and convex, concave-drain and other processes. Printing. In short, the anti-counterfeiting effect is improved by the complication of the printing process.

Rainbow printing anti-counterfeiting technology

Multiple colors can be printed at a time, and the middle color transition is soft. The effect is difficult to achieve with a multi-color overprint method. Even if the counterfeiter uses a rainbow printing method, it is difficult to determine the distance between the partitions, thereby increasing the difficulty of counterfeiting. If such a process is used on a large area of ​​shading, its anti-counterfeiting effect will be more pronounced.

Special Printing Technology for Bills

The technology is used for discoloration coating in the printing process and printing in the coating process, so that the invoices printed out have very strict associativity, and are suitable for the printing of triple or triple bonds. After copying the parts of the first customer name and the capital amount column of the triple bond, the invoices are displayed in different colors; the customer name and capital amount column on the back of the second link are also processed so that the third copy is written after One-third of the color of the word is different from other parts, and any one of them cannot leave a ticket that meets the requirements. It can effectively prevent the user from opening a single document, opening it in a false manner, and has the features of anti-counterfeiting, anti-counterfeiting, and easy identification.

Barcode anti-counterfeiting technology

Invisible barcodes (covered implicit barcodes, invisible barcodes for photochemical processing, invisible barcodes printed with invisible ink, etc.), or metal barcodes enable barcodes to have anti-counterfeiting capabilities at the same time as code.
