A commodity barcode is a symbol consisting of a set of regularly arranged bars and spaces and their corresponding characters, and is used to indicate the symbol of the product information. The strips are dark and empty, and are used for scanning and reading of barcode reading devices. Its corresponding character consists of a set of Arabic numerals for people to directly read or use the keyboard to input data to the computer. This set of empty spaces and corresponding characters
The information represented is the same.
Barcode technology is born with the development and application of computer and information technology. It is a new technology that integrates coding, printing, identification, data collection and disposal.
The use of bar code scanning is a major trend in the future market. In order for goods to be freely and universally circulated throughout the world, companies must follow the rules governing the management of bar codes of goods, whether they are designing and manufacturing, applying for registration or using commodity barcodes.
At present, the commonly used codes in the world are ENA barcode, UPC barcode, two-five barcode, interspersed two-five barcode, Kudba barcode, Sanjiu barcode and 128 barcode, etc., and the most commonly used commodity is the EAN commodity barcode.
The specification size of the commodity barcode is 37.29 mm x 26.26 mm, and the magnification is 0.8-2.0. When the printing area is allowed, a barcode of 1.0x or higher should be selected to satisfy the reading request.
The smaller the magnification, the higher the printing accuracy request, and when the printing accuracy cannot satisfy the request, it is difficult to form a bar code.
Since the reading of the barcode is performed by the bar code and the empty color illuminance, under normal conditions, only the requested color of the illuminance (PCS value) can be used.
Usually used in pastel colors, such as white, orange, yellow, etc., using dark colors, such as black, dark green, dark brown and so on. The best color match is black and white. According to the theoretical experience of bar code detection, red, gold, and light yellow are not suitable for color, and transparent and gold cannot be used as empty colors.
The EAN-8 commodity barcode is an eight-digit commodity barcode for identification, and consists of a 7-digit commodity item code and a 1-digit numeric check digit.
The birth of commodity barcodes has greatly facilitated the circulation of commodities, and modern society has been inseparable from commodity barcodes. According to statistics, at present, there are 500,000 kinds of products in China that use internationally accepted commodity barcodes. After China's participation in the WTO, enterprises will surely win more space for activities on the international stage. To be in line with international practices and to comply with the needs of international trade and economics, companies must not wait for commodity barcodes.
