What is a coder - and why the term is changing
In industrial labeling, the term Encoder often used for devices with which variable information such as date, batch number, serial number or barcodes can be applied to products.
Classic coders are usually stationary inkjet or thermal transfer systems, integrated into production lines and designed for high volumes.
In many applications, however, these systems reach their limits - for example with small series, changing products, manual processes or Markings outside the production line.
Here comes the mobile coders into play.
What is a mobile coder?
A mobile encoder is a Hand-held labeling device, with the variable information directly on the product can be printed - independent of a fixed production environment.
Typical areas of application:
- Batch labeling
- Date and time marking
- Serial numbers
- Barcodes and QR codes
- Documentation and test markings
In contrast to stationary coders, a mobile coder offers Maximum flexibility with high print quality at the same time.
Direct printing without a label - the modern form of coding
Modern mobile coders work with the Thermal Inkjet (TIJ) process and enable the Direct printing without label. The ink is applied to the product with pinpoint accuracy - without backing material, without adhesive, without detours.
Advantages of direct printing compared to labels and classic coders:
- no label material
- No storage of labels
- Less waste
- Quick conversion
- Direct labeling on the product
- Ideal for changing content
REINER jetStamp® - mobile inkjet coder for industrial applications
The REINER jetStamp® devices are often referred to as mobile inkjet coders are used. They combine the advantages of classic coding systems with the flexibility of a hand-held device.
Typical applications:
- Batch labeling in the food industry
- Date printing in logistics and shipping
- Labeling of cardboard boxes, pallets and wood
- Marking of metal and plastic parts
- Documentation printing in incoming goods or quality assurance
jetStamp® 1025 - mobile coder for variable markings
The jetStamp® 1025 is a mobile encoder for the Manual direct printing of variable information. Texts, barcodes, logos, serial numbers, date, time and batch identification are printed directly onto the product at the touch of a button without movement, without fixed installation.
Typical for the jetStamp® 1025:
- 100 % mobile
- Direct printing without label
- Variable contents
- Intuitive, display-guided operation
- Ideal for flexible, manual processes

jetStamp® 1025 sense - Coder with sensor connection
The jetStamp® 1025 sense extends the principle of mobile coding to include a Integrated sensor interface. Measured values, signals or scanned data trigger the print automatically directly at the place of origin.
The jetStamp® 1025 sense is particularly suitable for:
- Measuring and testing processes
- Processes requiring documentation
- Automated labeling without PC
- Barcode and sensor signals

Mobile coder or classic coder - which solution when?
| Application | Classic encoder | Mobile coder |
|---|---|---|
| High quantities | ✔ | – |
| Fixed production line | ✔ | – |
| Small series | – | ✔ |
| Changing products | – | ✔ |
| Manual processes | – | ✔ |
| Marking outside the line | – | ✔ |
Conclusion: rethinking coding - mobile, flexible, direct
The term Encoder no longer just stands for large, stationary systems.
Modern mobile encoders such as the REINER jetStamp® devices enable the Direct printing without label, exactly where it is needed.
For companies that Flexible processes, Changing markings and Practical solutions the mobile coder is an efficient alternative to classic coding systems.
