At present, there are ENA barcode, UPC barcode, 25 barcode, crossed 25 barcode, Kudba barcode, Sanjiu barcode and 128 barcode commonly used in the world, and EAN commodity bar code is the most commonly used commodity.
EAN commodity bar code, also known as General commodity bar code, is formulated by ean international and is widely used all over the world. It is the most widely used commodity bar code in the world. This kind of commodity bar code is being used in China at present. EAN commodity bar code is divided into EAN-13 (standard version) and EAN-8 (shortened version).
ean-13 universal commodity bar code generally consists of prefix, manufacturer code, commodity code and check code. The prefix code in commodity bar code is used to identify the country or region, and the code is given in ean international. For example, -9 represents the United States and Canada. 45-49 stands for Japan. 69-692 stands for Chinese mainland, 471 stands for Taiwan Province and 489 stands for Hong Kong Special Administrative Region. The empowerment of manufacturer's code is organized by article coding in various countries or regions, and in China, the national article coding center gives manufacturer's code. Commodity codes are codes used to identify commodities, and the right to assign codes is exercised by the product manufacturers themselves. The manufacturers themselves decide which Arabic numerals to use for their own commodities according to the prescribed conditions. Commodity bar code finally uses the 1-digit check code to check the correctness of the L-12th digit code from the left in commodity bar code.
commodity bar code's coding follows the principle of uniqueness, so as to ensure that commodity bar code will not be repeated all over the world, that is, a commodity item can only have one code, or a code can only identify a commodity item. Commodities with different specifications, different packages, different varieties, different prices and different colors can only use different commodity codes.
the standard size of commodity bar code is 37.29mmx26.26mm, and the magnification is .8-2.. When the printing area permits, bar codes with a magnification of more than 1. should be selected to meet the reading requirements. The smaller the magnification is, the higher the printing accuracy is. When the printing accuracy can't meet the requirements, it is easy to read the bar code.
because the bar code can be read by the blank color contrast of the bar code, generally, as long as the color can meet the requirements of contrast (PCS value), it can be used. Usually, light colors are used as empty colors, such as white, orange and yellow, and dark colors are used as strips, such as black, dark green and dark brown. The best color matching is black stripes and white spaces. According to the practical experience of bar code detection, red, gold and light yellow should not be used as bar colors, and transparent and gold should not be used as empty colors.
ean-8 commodity bar code refers to an 8-digit commodity bar code for identification, which consists of a 7-digit commodity item code and a 1-digit checker.
The birth of commodity bar code has greatly facilitated the circulation of commodities, and modern society can't live without commodity bar code. According to statistics, at present, 5, kinds of products in China have used the internationally accepted commodity bar code. After China's accession to the WTO, enterprises will certainly win more space for activities on the international stage. To be in line with international practices and meet the needs of international trade, enterprises should not treat commodity bar code badly.
