Advantages and production methods < br / >
< br / >
bar code label is easy to make, no special requirement to equipment and materials, identification equipment easy to operate, do not need special training, and the equipment is relatively cheap. Easy to make, easy to read, input speed, high reliability, read in the high degree of standardization of equipment, with computer and other control equipment online use, perfect performance. < br / >
< br / >
the production of bar code printing, is commonly used in through the bar code printer or laser engraving machine to print the barcode. Bar code printer and ordinary printer is the big difference, bar code printer to print is based on heat transfer, with carbon belt for print media type, with different materials of carbon belt can realize high quality printing effect and in the case of unattended to realize continuous high-speed printing. < br / >
< br / >
high technology content, complicated manufacturing process; Can store a lot of words, pictures, fingerprint; A bar code message, infinite changes; It is difficult to decipher special encryption technology; Limited to the disposable use, belong to the national patent technology, one of the country. Characteristics of < br / >
< br / >
1. Uniqueness: same specification the same product code corresponding to the same products, the same products in different specifications should deal with different product code. According to the different nature of the product, such as: weight, packing, specifications, smells, colors, shapes, and so on, to give different commodity code.



  2. Boast skillful: product code once assigned, no longer changes, and is for life. When this product is no longer production, its corresponding product code can only be shelved, shall not be repeated use of redistribution to other goods.



  3. No meaning: code to ensure there is enough capacity to meet the needs of the frequent replacement products, will eventually adopt sequence code without meaning. Conclusion < br / >
< br / >
1. Bar code itself, there is no authenticity, the existence of authenticity is a commodity packaging;



  2. Is not in the middle of the item code web query less than bar code corresponding to the goods is fake, because the quality of the merchandise manufacturers in their local inspection and quarantine bureau to apply for to their enterprise commodity barcodes, passes through a long time to send to a server in the middle of the country goods coding, if buy the query in this period of time the goods from the bar code, is unable to query to;



  3. Commodity bar code used is a deadline, the enterprises need to renew every year to continue to use the bar code, otherwise, the bar code will be deleted from among items code website, if the buyer is in this period of time inside of the goods from the bar code, is also unable to query to. Classification < br / >
< br / >
1. Invisible barcode: no damage packaging decoration integral effect, also does not affect the bar code features, the purpose of the same invisible barcode after contact, generally counterfeiters are difficult to copy, the anti-counterfeit effect is very good, and there is no matching color when printing problems.



  2. Two dimensional barcode, coding technology, laser technology, computer technology, encryption anti-counterfeiting technology and optical technology such as complicated technological process and production of high-tech multiple anti-fake products < br / >
< br / >
3. Metal bar code: metal foil after plating, generally in the surface of the bar code, and covering a layer of polyester film, the bar code is to use a dedicated metal bar code reader to read.



  4. Two dimensional metal: belong to foil after plating, generally in the surface of the bar code, and covering a layer of polyester film, the bar code is to use a dedicated metal bar code reader to read. < br / >
< br / >
5 implied magnetic code: powder weak magnetic materials magnetic ink, in order to offset printing, screen printing and other printing way will its mechanical characteristics and magnetic characteristics were mixed coding copy. < br / >
< br / >
6 other: reasonably determine the location of the barcode, can also achieve the purpose of anti-counterfeiting. < br / >
< br / >
use barcode scanning is the trend of the future market circulation. In order to make the flow of goods to freedom in the world, widely, enterprise both in design and production, application for registration or use of commodity barcodes, all you need to follow the relevant provisions of the commodity bar code management.
