What is a barcode?
A barcode is a visual representation of data that can be read using a scanner. The structures of bars or dots contain encrypted information that enables fast and error-free reading. Barcodes are used in almost all areas of industry - from product labeling to logistics and medical technology.
Each barcode consists of several basic elements:
- Light-dark contrasts: They enable machine reading.
- Start and stop characters: Define the start and end of the code.
- Data areas: Contain the coded information.
- Check digits: Ensure the correct transmission of data.
Depending on the application, there are different barcode standards that are optimized for different industries.
Recognizing barcode types - What types are there?
A barcode type is recognized by special scanners or software. These read the specific characteristics of the code, including bar lengths, spacing and character structures. The choice of the right code always depends on the planned application and the required data volumes.
Barcode vs. 2D code - differences and areas of application
- Barcodes (1D barcodes): consist of a series of vertical bars and store limited information, such as product numbers or serial numbers. They are widely used in areas such as logistics, retail and manufacturing.
- 2D codes: Square codes with a complex data structure, e.g. QR codes or DataMatrix codes. They store significantly more data on a more compact surface. They are used in marketing, maintenance or product tracking, as they can be easily scanned with modern devices.
Which barcode types are relevant for industrial applications?
Various barcode types are used in industrial applications, each of which is suitable for specific requirements and areas.
- Code 39 & Code 128 are often used in the automotive and manufacturing industries as they are robust and versatile.
- EAN and UPC codes, on the other hand, are the standard for fast product identification in the packaging and food industry
- DataMatrix is ideal for small components and direct part marking (DPM) due to the high data density in a very small space.
- GS1-128 codes are used for global flows of goods and logistics processes. This enables standardized product tracking worldwide.
Barcode printing in the industry
Barcodes are indispensable in industrial production. They enable products to be identified quickly, reduce sources of error and ensure smooth process control. They make an important contribution to safety, particularly in the area of hazardous substance labeling, by enabling clear assignment.
Quality requirements for barcodes - challenges
Depending on the area of application, barcodes have to be applied to a wide variety of materials and surfaces. Various factors can influence the print quality - including uneven packaging materials, weather influences or chemical stress. In addition, there are industry-specific regulations that prescribe certain barcode standards.
For a barcode to be scanned without any problems, it must meet certain quality criteria. A high contrast between the bars and the background is just as important as a precise bar width. In addition, barcodes must be printed in such a way that they remain permanently legible even under demanding conditions - for example in the chemical or food industry.
Printers for industrial barcode printing
Various printing technologies are used for industrial barcode printing, which offer different solutions depending on the requirements. Thermal transfer printing ensures consistent results, while laser marking takes place directly on materials such as metal or plastic. Thermal inkjet (TIJ) enables high-resolution printing. The ResMark 5000 from Diagraph offers a flexible solution for large character printing and is suitable for non-contact marking of packaging and cardboard boxes in production lines.
Thermal transfer printers - Durable and precise barcodes
Thermal transfer printer are ideal for industrial use when durable, abrasion-resistant and high-resolution barcodes are required. They work with a special ribbon technology that transfers the printed image directly onto labels or flexible packaging. With a resolution of up to 600 dpi, they produce razor-sharp codes that remain consistent even under extreme conditions such as heat or exposure to chemicals. Another advantage is the space-saving design, which enables easy integration into existing production lines.
Laser marker - Permanent marking without consumables
Laser marker are the perfect choice for companies that require a contactless, durable and low-maintenance marking solution. They create barcodes, serial numbers and other markings through targeted laser engraving without using ink or labels. This technology is particularly suitable for materials such as metal, plastic, glass or cardboard and offers excellent readability and counterfeit protection. The low maintenance requirements and long service life make laser markers extremely economical.
Thermal inkjet printers - High-resolution printing with flexible application
Thermal inkjet printer (TIJ) offer a compact and user-friendly solution for industrial barcode printing. They use HP cartridge technology and deliver high-resolution print images with up to 600 dpi. These printers are versatile and can be used on materials such as cardboard, foils, metals and plastics. Easy maintenance, fast ink cartridge replacement and high print speeds make them ideal for efficient and cost-effective business coding solutions.
Large character printer ResMark 5000 - Perfect for large barcodes
The ResMark 5000 is a powerful large character printerespecially for industrial applications. With a print height of up to 100 mm, it is perfect for large barcodes on cardboard and other porous materials. Thanks to its modular design, several print heads can be combined. The ResMark 5000 is non-contact, making it ideal for fast production lines. With automatic printhead cleaning and a robust design, it offers a reliable and low-maintenance solution.
