Electronic inkjet marking device for printing variable text, numbers, dates and time on suitable non-absorbent surfaces using REINER MP fast-drying ink.

The REINER jetStamp® 791 MP is an electronic inkjet marking device from the jetStamp 790/791/792 family, developed for printing short variable information directly onto suitable products, components, packaging and documents.

The MP designation is important. REINER developed the MP versions for marking difficult or non-absorbent materials using compatible quick-drying ink, including suitable:

• Metal
• Plastic
• Glass
• Coated surfaces
• Other non-porous materials

The jetStamp 791 MP can print information such as text, numbers, date and time in one- or two-line impressions, with a maximum print width of approximately 42 mm.

A particularly useful characteristic of the 791 version is its computer-oriented operation. REINER documentation describes the jetStamp 791 as supporting Click & Stamp functionality for transferring and printing suitable text originating from PC applications such as Microsoft Word and Excel.

The jetStamp 791 MP is an established earlier-generation REINER product. For a completely new marking project, customers should also compare the requirement with REINER's current marking portfolio before selecting an older model.

What Is the REINER jetStamp 791 MP?

The jetStamp 791 MP combines an electronically controlled stamp with inkjet printing.

Instead of using a fixed rubber impression, information is electronically defined and then printed directly onto the required surface.

Typical content can include:

Product ABC

LOT 001245

06.09.2026

or combinations of text, date, time and numbering within the supported imprint format.

This can be useful when information changes regularly between products, documents, production batches or processing steps.

Why Is the “MP” Version Important?

The surface being marked is one of the most important factors when selecting a REINER device.

Conventional ink works naturally with absorbent materials such as paper because the material absorbs the ink.

Materials such as:

• Metal
• Plastic
• Glass
• Coated packaging

can behave differently because ink remains on the surface rather than being readily absorbed.

The MP version of the jetStamp family is designed for these more demanding surfaces using compatible fast-drying MP ink.

However, the term MP does not mean that every possible plastic, metal, coating or glass surface will produce identical results.

Surface testing remains important.

Suitable Marking Applications

The jetStamp 791 MP can be considered for marking information such as:

• Production dates
• Expiry or best-before information where appropriate
• Lot numbers
• Batch numbers
• Sequential numbers
• Inspection information
• Quality-control markings
• Short product identification
• Internal tracking information
• Date and time information
• Short variable text

The exact marking format should be checked against the available print area and character limits.

Print Area and Character Format

REINER documentation for the jetStamp 791 family specifies a maximum print width of approximately:

42 mm

The device supports:

One-line impressions

or

Two-line impressions

Character height is approximately:

3.2 mm

Depending on the selected character width, up to approximately:

20 characters per line

can be accommodated.

This makes the 791 MP suitable for compact identification information rather than large-format graphics or extensive product descriptions.

PC-Based Printing and Click & Stamp

One of the distinctions of the jetStamp 791 is its PC-oriented functionality.

REINER documentation describes Click & Stamp software functionality that allows suitable text from applications such as Microsoft Word and Excel to be used for marking.

Applicable text can be transferred from PC applications and printing can be triggered through the computer or directly at the stamp.

This can be useful where marking information already exists in an office or production workflow and needs to be transferred to the physical product.

Because the jetStamp 791 is an established earlier-generation product, customers intending to connect it to a modern computer environment should verify current software, operating-system and interface compatibility before ordering.

Stored Impressions

The jetStamp 791 family can store up to 25 different impressions in device memory.

This can help when an operation regularly switches among predefined marking formats.

For example, different impressions might be prepared for:

• Receiving
• Inspection
• Production
• Quality control
• Batch identification

The user can then select the appropriate stored impression instead of rebuilding the content for every marking task.

Standard jetStamp vs MP Version

The distinction should be made before ordering.

Standard Version

Primarily intended for suitable absorbent printing surfaces.

MP Version

Designed for suitable non-absorbent surfaces using compatible quick-drying MP ink.

If the application involves metal, plastic, glass or coated material, the exact MP device and ink should be evaluated rather than assuming that a standard cartridge will provide suitable adhesion and drying.

jetStamp 790 MP vs 791 MP vs 792 MP

These related models should not be treated as identical.

jetStamp 790 MP

The 790 is the more mobile member of the earlier family and uses rechargeable battery operation.

jetStamp 791 MP

The 791 is particularly associated with PC-based Click & Stamp operation, allowing applicable content from PC applications to be incorporated into the marking workflow.

jetStamp 792 MP

The 792 is designed more toward stationary or machine applications, including installation into production environments, and operates from mains power rather than as the battery-operated 790 configuration.

Therefore, a customer asking for 791 MP should not automatically be quoted a 790 MP or 792 MP without understanding why the 791 was specified.

Applications

The REINER jetStamp 791 MP may be considered for:

• Manufacturing
• Production
• Quality assurance
• Goods receiving
• Warehouse identification
• Component marking
• Packaging
• Batch identification
• Lot marking
• Date marking
• Inspection marking
• Plastic component identification
• Metal component marking
• Coated packaging marking
• Laboratory and technical workflows
• Administrative and document applications

Suitability depends on the actual material, required print content and operating conditions.

Ink and Surface Compatibility

Ink selection deserves particular attention.

Even within the general category of "plastic," different materials can have very different surface characteristics.

For example:

ABS ≠ PET ≠ PE ≠ PP ≠ PVC

Similarly, painted, anodized, polished or coated metals may behave differently.

Before committing to a production process, customers should ideally test:

Actual REINER MP Ink

Actual Material

Actual Required Imprint

Actual Drying and Handling Conditions

This provides much better evidence than relying only on a general statement such as "suitable for plastic."
