Printing directly onto metal
Durable, precise, without labels
From smooth aluminum parts to galvanized steel: With REINER, direct printing on metal is reliable, high-contrast, and smudge-proof. Our mobile inkjet printing systems print serial numbers, QR codes, best-before dates, logos, or batch numbers directly onto metal surfaces—without labels or carrier material. Ideal for components, workpieces, housings, or metal packaging that need to be marked in a robust and legible manner.

Hurdles in the coding of metal
Why standard solutions are often not enough

Metal is hard, smooth, and often difficult to label. This is precisely where REINER's mobile marking devices show their strength. Contactless inkjet technology creates a clear, strong impression directly on the surface.
Typical requirements
- Clear print images on stainless steel, aluminum, galvanized steel, or anodized surfaces
- Imprinting of text, logos, QR codes, serial numbers, or best-before dates
- No labeling or re-sticking necessary
- Smudge-proof
- Ideal for small series, custom-made products, and variable applications
- Optionally software-controlled – with PCset graphic or ERP connection
Typical challenges
-
Smooth, non-absorbent surface makes adhesion and drying more difficult
-
Residues from production impair the print image
-
Coated or painted metals react differently to inks
-
High abrasion and scratch resistance requires particularly resistant labeling
-
Temperature differences (heat/cold) can affect adhesion and legibility

Different surfaces
Printing on smooth, brushed, or coated metals
Special technical features for metal
Labeling that adapts to your material
-
Smooth, non-absorbent surface requires special inks with high adhesion
-
Different types of metal and coatings influence adhesion and drying
-
Temperature stress can affect the durability of the labeling
-
Reflection and dark surfaces require high contrast for good legibility
Practical example
Applications, experiences, and tips
A medium-sized manufacturer of industrial electronics from Bavaria produces control units and sensor systems for mechanical engineering. The devices have aluminum and powder-coated metal housings on which type labels were applied. These have now been replaced by the jetStamp® 990.
Result:
- Elimination of separate type labels
- Faster assembly processes
- Permanent labeling directly on the product
- Reduced material and storage costs
- Uniform typeface

Our solution
The versatile inkjet printer for industrial metal marking. Fast, mobile, and robust—perfect for industrial applications.
Precision clip CAP990
Flexible marking on metal surfaces
The jetStamp 990 is suitable for marking metal parts, components or metal packaging. Serial numbers, batches or production data can be applied directly to smooth metal surfaces and ensure clear identification in the production process.
✓ Print height up to 12.5 mm (2 lines of 20 characters each)
✓ Variable content (date, batch, serial number)
✓ Suitable for smooth metal surfaces
✓ Mobile and flexible use in production

jetStamp® 1025
Highly visible marking on metal parts
With the jetStamp 1025, metal parts and components can be marked clearly and legibly. Larger print images enable the display of serial numbers, barcodes or production data directly on components or metal surfaces.
✓ Print height up to 25 mm
✓ Print text, barcode, date and serial number
✓ Ideal for parts and metal components
✓ Mobile or stationary use in the production process

jetStamp® 1025 sense
Scan data and mark metal parts directly
The jetStamp 1025 sense combines data capture and marking in one device. Barcodes can first be scanned and then printed directly onto metal parts or components. This facilitates documentation and traceability in the production process.
✓ Integrated scanner for codes and data
✓ Print height up to 25 mm
✓ Automatic labeling after data acquisition
✓ Ideal for production and quality processes
Flexible and economical metal marking
