A barcode is a graphical identifier that arranges multiple black bars and blanks of varying widths according to a certain coding rule to express a set of information. The common barcode is a parallel line pattern composed of black bars (referred to as bars) and white bars (referred to as spaces) with significantly different reflectivity. Barcodes can indicate many information such as the country of production, manufacturer, product name, production date, book classification number, mail start and end locations, category, date, etc. Therefore, they are widely used in many fields such as commodity circulation, book management, postal management, banking system, etc.
There are many types of product barcodes on the market, and the most commonly used one is EAN13 barcode. EAN13 barcode is a widely used product barcode standard,
Prefix code: This part is used to identify the country or region of production of the product. The prefix code of EAN13 barcode is usually composed of numbers, used to distinguish different countries and regions.
Manufacturer identification code: used to identify the manufacturer or brand that produces the product. This part of the code is usually represented by specific numbers or combinations of numbers, ensuring that each vendor has a unique identifier.
Product item code: This section is used to identify specific product items. It is usually composed of a series of numbers used to distinguish different types or models of goods.
Verification code: used to verify the correctness of barcodes. The verification code is calculated through a specific algorithm to ensure the accuracy and reliability of the barcode.
The ITF-14 barcode is a 14 digit barcode designed specifically for cardboard boxes. It adopts the GTIN-14 code structure and consists of three parts: packaging indicator, internal item code, and verification code. This barcode is mainly used to label boxes or logistics units, such as pallets, but not for settlement. The character set of ITF-14 barcode is composed of digits 0-9, including the carrier bar, left blank area, start symbol, 7 pairs of data symbols, stop symbol, right blank area, and characters for human recognition. The carrier bar serves to protect the barcode image and can be a rectangular box surrounding the barcode or two vertical bars spanning the top and bottom of the data expression bar.
The types of packaging barcodes mainly include EAN-13 barcode, EAN-8 barcode, UPC-A barcode, UPC-E barcode, etc. These barcodes each have their own characteristics and uses, suitable for different products and scenarios.
EAN-13 barcode: composed of a 13 digit character code, also known as EAN standard version barcode, widely used for product identification worldwide and domestically.
EAN-8 barcode: also known as shortened code, used for printing and packaging of goods for sale. When there is not enough space to print standard barcode on the product packaging, the product can be coded into a B-digit code for use in packaging with limited space.
UPC-A barcode: used for both product sales and product storage and transportation packaging, consisting of 12 digit character initials, known as the standard version of UPC barcode, mainly used in the United States and Canada.
UPC · E barcode: It is a shortened version of UPC barcode used for product sales packaging, consisting of an 8-digit character code. Only used when the product is too small to print UPC-A barcode.
Born in Tokyo, Japan in 1957, graduated from Hosei University with a Bachelor's degree in Electrical Engineering in 1980, and joined Denso Corporation (now Denso Corporation) in the same year. He successfully developed QR codes in 1994, which passed the JIS standard in 1999 and the IS0 standard in 2000.

A barcode reader (usually a laser scanner or CCD) emits a beam of light onto the barcode and then receives the reflected light. The barcode is composed of black and white stripes of different widths, with the black stripes absorbing light and the white stripes reflecting light. By detecting the strength and frequency of reflected light, converting it into numbers or letters, the barcode reading is completed.
Mobile scanning recognition: In recent years, a very popular way of recognition is to capture barcodes through mobile phone cameras and then use image recognition technology to analyze the information of the barcodes. Usually, numbers or letters are analyzed by identifying the width ratio of black and white stripes.
The color of barcodes is usually black, but sometimes in order to reduce printing color, color is used. We try to use dark colors as light colors cannot be recognized. In addition, it is best to pad white or light colors under the barcode.
As a professional customized printing packaging manufacturer, ITIS will inform customers of the relevant barcode standards when they propose design requirements, thereby reducing customer time waste.
