Discuss the security printing process in wine printing
A high-quality bottle of wine is like a beautiful work of art, and in this regard, the bottle and label play a pivotal role. In the field of packaging printing, the printing process of wine labels has also attracted much attention. The following is a discussion of wine labels and their printing processes.
1. Printing of the main pattern of the wine label
The main pattern of the wine label is often based on some delicate and exquisite, simple and elegant patterns, and offset printing is the most suitable printing method for the processing of these patterns, because it has good dot reduction characteristics and fine text and line reproduction ability. In addition, the offset printing process has been developed very perfectly, and the supporting raw and auxiliary materials have also been fully matured, and the production cost is low.
2. Printing of other parts of the wine label
If the text description part is very small text, and contains some anti-counterfeiting microtext and patterns, you can also use offset printing. If it's just normal-sized text and barcodes, and contains some color blocks, you can consider flexographic printing.
3. Post-printing processing of wine labels
The wine label should give people a sense of nobility and stability, so after printing. There is also some post-processing. For example, in the company's logo or some decorative lines, the gold and silver effect is increased by cold transfer and hot stamping.
Printing anti-counterfeiting technology is a comprehensive anti-counterfeiting technology, including anti-counterfeiting design plate making, precision printing equipment and supporting ink, paper, etc. Purely from the perspective of printing technology, printing anti-counterfeiting technology mainly includes: engraving plate making, computer design pattern, gravure printing, rainbow printing, pattern docking, double-sided printing technology, multi-color wiring printing, multi-color overprinting, microprinting technology, refractive latent shadow, invisible image and image scrambling printing. Here we first introduce the barcode anti-counterfeiting technology and watermark counterfeiting.
Barcode anti-counterfeiting technology: Commodity barcode is a kind of code of goods, which is designed by humans for effective management of computers and other goods. If we can reasonably use commodity technology, including the reasonable selection of the carrier of the barcode, the reasonable selection of the printing method and the printing machine, the reasonable selection of the printing position, etc., then it is possible to make the commodity barcode technology have an anti-counterfeiting effect.
Watermark paper: watermark paper in the manufacturing process, can use technical means to make the required logo, pattern, etc. into the paper, these patterns are not easy to see under normal circumstances, only against the strong light can be seen, China's issuance of larger denominations of RMB are mostly printed with watermark paper. In today's era of advanced science and technology, watermarking is still recognized as an effective anti-counterfeiting technology by anti-counterfeiting experts around the world, and continues to be adopted and developed by various countries. For example, in 1996, the new version of the 100 US dollar paper used the "Fulan Klin" portrait watermark, and China's large-denomination RMB paper made "Tiananmen", "Mao Zedong" and other watermarks. Watermarks have been widely used in other ticket papers in addition to currency paper. There are several types of watermarks in the position of the paper: fixed, non-fixed and semi-fixed. The production process of watermark paper was invented by Italian papermaking experts in the 13th century. Because it integrates complex processes such as design, engraving, netting, and papermaking in the manufacturing process, it often makes counterfeiters helpless. Checking the watermark is also one of the most effective ways to distinguish the real from the fake. Of course, a large number of watermarks on the packaging decoration anti-counterfeiting is not economical at this stage, with a special material to develop an ink, the imitation watermark mark is printed on ordinary coated paper, and the watermark effect is extremely similar.
