Barcode, also known as barcode, is a graphic identifier that arranges multiple black bars and blanks with different widths according to certain coding rules to express a group of information. A common bar code is a parallel line pattern composed of black bars (referred to as bars) and white bars (referred to as empty bars) with very different reflectivity. Bar code can mark the country of production, manufacturer, commodity name, production date, book classification number, mail start and end location, category, date and many other information, so it is widely used in many fields such as commodity circulation, book management, postal management, banking system and so on, Danmajet inkjet printer can quickly print variable bar code information onto labels and films for traceability.

Data matrix, formerly known as data code, was invented by international data matrix (ID matrix) in 1989. The data matrix can be divided into two types: ecc000-140 and ecc200. Ecc000-140 has a variety of error correction functions at different levels, while ecc200 generates polynomial to calculate the error correction code through Reed Solomon algorithm, and its size can be printed into different sizes according to requirements, but the error correction code used should match the size. Because its algorithm is easier and the size is more flexible, Therefore, ecc200 is generally used. Danmajet provides customers with UV DOD digital web press and single sheet variable data printing solution for labels, films, cards, tags.

Unique device identification (UDI) is the electronic ID of medical device products.

Serial number, also known as "machine code", is the same item, which is generally the world's unique identification code of electronic products. Commonly used for anti-counterfeiting. The biggest feature is the only one.

QR code code is a matrix two-dimensional code symbol developed by Denso company in September 1994. It has the advantages of large information capacity, high reliability, multiple text information of Chinese characters and images, strong confidentiality and anti-counterfeiting, etc. of one-dimensional bar code and other two-dimensional bar codes.

1. Symbol specification from version 1 (21 × Module 21) to version 40 (177 × 177 modules), 4 modules will be added on each side for each improved version.

2. Data type and capacity (refer to the maximum specification symbol version 40-L):

Digital data: 7089 characters

Alphabetic data: 4296 characters

8-bit byte data: 2953 characters

Chinese character data: 1817 characters

3. Data representation:

Dark modules represent binary "1" and light modules represent binary "0".

4. Error correction capability:

Level L: Data codeword with error correction of about 7%

Level M: Data codeword with error correction of about 15%

Level Q: Data codeword with error correction of about 25%

Level H: Data codeword with error correction of about 30%

Date is very common. The validity date of food packaging and the production date of products are a direct and effective traceability method. Danamjet inkjet inkjet can print various forms of dates, which is corrosion-resistant and scratch resistant.

GS1 (global standard 1) is an organization established by the United States unified code Committee in 1973. The system has a global cross industry identification standard system and information exchange standard system for products, transportation units, assets, locations and services, so that products can be scanned and read all over the world.

In the increasingly competitive global market, strict management and correct use of the company's logo with unified standards will provide a more effective, clearer and friendly market image. Logo is a visual way of information expression formed in people's long-term life and practice. It has a certain meaning and can be understood by people. It has a concise, clear and clear visual transmission effect. It is a special subject with strong practicability, involving psychology, aesthetics, chromatics and other fields. After refining, abstracting and processing in life practice, it is concentrated in the form of graphics, expresses certain spiritual connotation, transmits specific information, and forms a visual language for people to communicate with each other. Logo, as a visual graphic for identifying and conveying information, with its simple and beautiful modeling language, reflects the characteristics of the brand and the image of the enterprise. Danmajet thermal inkjet printer can print logo at high speed / high resolution / high resolution.
