Direct marking is a modern, efficient, and sustainable solution for product identification and coding.
Efficient, Durable Marking for Industry and Commerce
Direct marking is one of the most important methods for permanent identification of products, components, and packaging. In the era of Industry 4.0, growing traceability requirements, and complex supply chains, it is becoming increasingly strategic. Companies across industries – from automotive to food production to logistics – rely on direct marking systems to label products safely, efficiently, and in compliance with regulations.
TIJ marking systems and mobile handheld printers are particularly valued for their ease of use, low maintenance, and versatile applications.
Businesses seeking future-proof marking solutions benefit from the combination of stationary TIJ printers and mobile handheld systems – ensuring maximum efficiency across production, warehousing, and logistics.
What Is Direct Marking?
Direct marking refers to the immediate application of identification directly onto a product or its surface – without the need for labels or additional carrier materials. The marking can be applied to:
- Metal
- Plastic
- Glass
- Wood
- Cardboard
- Films
- Composite materials
Typical contents of direct marking include:
- Batch numbers
- Serial numbers
- Expiration dates
- Production dates
- Barcodes
- QR codes
- DataMatrix codes
- Logos or graphics
The goal is a permanent, tamper-proof, and easily readable marking.
Why Is Direct Marking Important Today?
Requirements for product marking have increased significantly in recent years. Key reasons include:
1. Traceability
Regulations – particularly in the food, pharmaceutical, and automotive industries – require full traceability of products.
2. Product Safety
Serial numbers and codes help prevent counterfeiting and enable targeted recalls.
3. Efficiency
Direct marking reduces the need for labels, minimizes process steps, and lowers long-term costs.
4. Sustainability
Fewer consumables mean less waste and reduced resource consumption.
Direct Marking Methods
There are several technologies for direct marking, including:
- Laser marking
- Dot peen marking
- Continuous Inkjet (CIJ)
- Thermal Inkjet (TIJ)
Each method has its specific applications. Thermal Inkjet (TIJ) technology, however, proves to be particularly flexible and cost-effective.
Direct Marking with TIJ Systems
What Is TIJ (Thermal Inkjet)?
Thermal Inkjet (TIJ) technology uses precise ink ejection through thermal impulses, enabling high-resolution printing directly onto a wide range of materials. Compared to other methods, TIJ offers:
- High print quality (up to 600 dpi)
- Low-maintenance operation
- Compact design
- Easy integration into existing production lines
