How to set up the barcode in the trademark? How to identify different barcodes?

Commodity barcode refers to a symbol composed of a set of regularly arranged bars, spaces and corresponding characters, which is used to represent certain product information. The bars are dark and the spaces are dark, which are used for scanning and reading with barcode reading equipment. The corresponding characters consist of a set of Arabic numerals for people to read directly or input data into the computer through the keyboard. The information represented by this group of spaces and corresponding characters is the same.

Bar code technology was born with the development and application of computers and information technology. It is a new technology that integrates coding, printing, identification, data collection and processing.

The use of barcode scanning is a major trend in market circulation in the future. In order to enable goods to circulate freely and widely around the world, companies must abide by the relevant regulations on product barcode management, whether designing and producing, applying for registration or using product barcodes.

The commonly used barcodes in the world currently include ENA barcode, UPC barcode, 25 barcode, crossed 25 barcode, Kudba barcode, 39 barcode and 128 barcode, etc., and the most commonly used barcode on goods is It is the EAN product barcode.

The EAN commodity bar code, also known as the universal commodity bar code, was developed by the International Article Numbering Association and is used all over the world. It is currently the most widely used commodity bar code in the world. Our country is currently promoting the use of this kind of commodity barcode in the country. EAN product barcodes are divided into two types: EAN-13 (standard version) and EAN-8 (shortened version).

EAN-13 universal product barcode generally consists of a prefix part, manufacturer code, product code and check code. The prefix code in the product barcode is a code used to identify the country or region. The coding authority is in the International Article Numbering Association, such as 00-09 representing the United States and Canada. 45-49 represents Japan. 690-692 represents mainland China, 471 represents Taiwan, and 489 represents Hong Kong SAR. The manufacturer's code is assigned to the article coding organization of each country or region. In my country, the manufacturer's code is assigned by the National Article Coding Center. Commodity codes are codes used to identify commodities. The right to assign codes is exercised by product manufacturers themselves. Manufacturers decide which Arabic numerals to use as product barcodes on their own products according to specified conditions. The product barcode finally uses a 1-digit check code to verify the correctness of the 1-12th digit code from the left in the product barcode.

The encoding of product barcodes follows the principle of uniqueness to ensure that product barcodes are not repeated worldwide, that is, one product item can only have one code, or one code can only identify one product item. Products of different specifications, different packaging, different varieties, different prices, and different colors can only use different product codes.

The standard size of product barcodes is 37.29mm x 26.26mm, and the magnification is 0.8-2.0. When the printing area allows, a barcode with a magnification of 1.0 or above should be selected to meet the reading requirements. The smaller the magnification of the barcode, the higher the printing accuracy requirement. When the printing accuracy cannot meet the requirements, it is easy to cause difficulty in reading the barcode.

Since the reading of barcodes is achieved through the color contrast of the barcode bar and space, in general, as long as the color can meet the contrast (PCS value) requirements, it can be used. Usually, light colors are used for hollows, such as white, orange, yellow, etc., and dark colors are used for strips, such as black, dark green, dark brown, etc. The best color combination is black bars and white space. According to practical experience in barcode detection, red, gold, and light yellow are not suitable colors for bars, and transparent and gold cannot be used as blank colors.

EAN-8 product barcode refers to an 8-digit product barcode used for identification, which is composed of a 7-digit product item code and a 1-digit check character.

The birth of commodity barcodes has greatly facilitated the circulation of commodities, and modern society is inseparable from commodity barcodes. According to statistics, currently 500,000 products in my country use internationally accepted commodity barcodes.

After my country joins the WTO, enterprises will surely gain more space for activities on the international stage. In order to be in line with international practices and adapt to the needs of international economic and trade, enterprises cannot wait for product barcodes.
