Black quick-drying REINER ink cartridge for direct marking on suitable non-porous and difficult surfaces including metal, plastic and foam with compatible jetStamp® 1025-series printers.

Product Overview

The REINER P5-MP3-BK is a black quick-drying ink cartridge developed for direct marking applications using compatible REINER jetStamp equipment.

REINER Designation: P5-MP3-BK

REINER Item Number: 1037 100-120

The MP3 formulation is particularly relevant when ordinary ink intended primarily for absorbent materials is not suitable for the surface being marked.

REINER identifies P5-MP3-BK for materials including:

• Paper
• Cardboard
• Wood
• Metal
• Plastic

REINER also documents a practical industrial application using P5-MP3-BK with the jetStamp 1025 to print directly onto non-porous foam, including machine-readable EAN barcodes.

This makes the cartridge relevant for customers using direct marking across mixed or difficult substrates rather than only conventional paper and cardboard.

The actual surface should nevertheless be tested before deployment. “Plastic,” “metal” and “foam” describe broad material families containing many different formulations, coatings and surface treatments.

What Is P5-MP3-BK?

Understanding the product name helps when selecting the correct cartridge.

P5 identifies the applicable REINER cartridge family.

MP3 identifies the ink formulation/application category.

BK identifies the ink colour:

BK = Black

The complete designation matters.

A cartridge should not be selected merely because another REINER ink is also black.

Different ink formulations are intended for different material and application requirements.

Why Does Ink Type Matter?

Direct inkjet marking depends on interaction between:

Ink

Surface

Printer

Required Marking

For absorbent material such as untreated cardboard, ink can penetrate into the material relatively easily.

Non-porous surfaces behave differently.

Materials such as:

• Plastic
• Metal
• Coated components
• Certain foams

may absorb little or no ink.

The ink therefore needs characteristics appropriate to that surface.

REINER positions its MP3 black ink as a quick-drying formulation for non-porous and difficult surfaces.

This is why selecting the correct cartridge is just as important as selecting the printer.

Suitable Materials

REINER documentation identifies P5-MP3-BK for:

Paper

Cardboard

Wood

Metal

Plastic

REINER additionally documents an industrial application involving:

Foam

The presence of a material in this list should not be interpreted as universal compatibility with every version of that material.

For example, plastics can include:

• PE
• PP
• PET
• PVC
• ABS
• Coated plastics
• Treated plastics
• Textured plastics

and metals can be:

• Bare
• Painted
• Coated
• Anodized
• Polished
• Oily
• Chemically treated

Surface testing remains important.

Printing on Plastic

P5-MP3-BK can be considered for suitable plastic direct-marking applications.

Potential markings may include:

• Product number
• Serial number
• Batch number
• Date
• Production information
• Barcode
• QR or other supported codes depending on printer capability

The exact plastic should be tested because surface energy, additives, coatings and contamination can influence ink adhesion and drying.

A successful print on one plastic does not prove performance on every plastic.

Printing on Metal

REINER also identifies metal as an application material for P5-MP3-BK.

Possible applications can include suitable:

• Components
• Parts
• Housings
• Production pieces
• Metal packaging

Metal surfaces can vary significantly.

A clean untreated metal surface may behave differently from painted, powder-coated, anodized, polished or oily metal.

Testing the actual component is therefore recommended where durability is important.

Printing on Foam

This is a particularly useful verified application for P5-MP3-BK.

REINER documents the combination:

jetStamp 1025 + P5-MP3-BK

for direct printing onto foam.

In the documented application, variable information including EAN barcodes and numbering is printed directly onto foam sheets, with production information transferred from an ERP workflow to the jetStamp 1025.

This demonstrates why the MP3 formulation can be useful for unusual surfaces where applying conventional labels may be inconvenient.

It does not mean every foam composition will behave identically.

Paper, Cardboard and Wood

Although MP3 is particularly interesting for difficult and non-porous surfaces, REINER also identifies:

• Paper
• Cardboard
• Wood

among its supported material categories.

However, customers working only with ordinary absorbent paper, cardboard or wood should not automatically assume MP3 is necessary.

REINER provides other ink formulations for different material requirements.

The cartridge should therefore be selected according to the actual application rather than simply choosing the formulation with the broadest-looking material list.

Direct Barcode Printing

When P5-MP3-BK is installed in a compatible REINER printer capable of generating machine-readable codes, it can be used in suitable direct barcode-marking applications.

REINER's documented foam application specifically demonstrates machine-readable EAN barcode printing with a jetStamp 1025 and MP3 ink.

Successful barcode printing still depends on:

• Barcode dimensions
• Module width
• Quiet zone
• Surface
• Ink contrast
• Print quality
• Surface deformation
• Scanner
• Required reading distance

For operational barcode applications, print samples should be tested using the scanner that will actually be deployed.

P5-MP3-BK vs Standard Ink

The correct choice depends primarily on the material.

A standard ink intended for absorbent materials may be appropriate for applications involving:

• Paper
• Cardboard
• Wood

P5-MP3-BK becomes particularly relevant when the application includes:

• Non-porous surfaces
• Plastic
• Metal
• Difficult surfaces
• Suitable foam

There is little benefit in choosing a specialized quick-drying formulation if the application does not require it.

P5-MP3-BK vs P5-MP4-BK

These two cartridges should not be treated as identical black inks.

Both belong to REINER's P5 family and both address applications extending beyond ordinary absorbent materials.

However, REINER's material documentation differentiates them.

P5-MP3-BK

REINER identifies:

• Paper
• Cardboard
• Wood
• Metal
• Plastic

and documents MP3 for difficult/non-porous applications such as foam.

P5-MP4-BK

REINER's material documentation extends the listed application range to:

• Paper

• Cardboard

• Wood

• Metal

• Plastic

• Glass

Therefore, customers should not substitute MP3 and MP4 merely because both cartridges contain black quick-drying ink.

The correct formulation should be selected according to the actual substrate and required marking performance.

Compatibility

P5-MP3-BK belongs to the current REINER P5 cartridge ecosystem associated with the jetStamp 1025 platform.

REINER's current accessory documentation explicitly identifies P5-MP3-BK together with:

• jetStamp 1025

• jetStamp 1025 sense

REINER also provides blue replacement seals specifically identified for:

P5-MP3-BK

and

P5-MP4-BK

in these machines.

Do not assume compatibility with a different REINER model merely because it uses black ink or belongs to the jetStamp family.

The exact printer model and cartridge designation should always be matched.

Cartridge Care and Sealing

Quick-drying ink is useful because the ink needs to dry rapidly on suitable non-porous surfaces.

The same characteristic means cartridge protection is important when the cartridge is not actively printing.

REINER provides dedicated replacement seals for the P5-MP3-BK/P5-MP4-BK cartridge ecosystem to help protect the cartridge from drying and maintain print quality.

Users should follow current REINER handling, storage, cleaning and sealing instructions for the exact cartridge.

Applications

P5-MP3-BK may be considered for suitable:

• Industrial product marking
• Plastic component marking
• Metal component marking
• Foam marking
• Packaging
• Manufacturing
• Production identification
• Batch coding
• Lot coding
• Date marking
• Serial numbering
• Barcode marking
• Product traceability
• Warehouse identification
• Logistics
• Variable-data marking

Things to Verify Before Ordering

For critical applications, testing the cartridge on the actual product is recommended before wider deployment.

Who Should Consider P5-MP3-BK?

This cartridge may be appropriate for users who:

• Operate a compatible REINER P5-cartridge printer
• Need black direct marking
• Print on suitable plastic
• Print on suitable metal
• Print on difficult or non-porous surfaces
• Need quick-drying black ink
• Mark suitable foam
• Require machine-readable markings on tested surfaces
• Need variable industrial direct marking

Who May Need Another Ink?

Another formulation should be considered where:

• Only conventional absorbent material is being marked and another REINER ink is more appropriate
• Glass is an important substrate and another REINER formulation is specified for that application
• A different ink colour is required
• The printer uses a different cartridge family
• MP3 does not provide satisfactory adhesion or durability on the actual surface

The correct ink should be selected from the application rather than from the cartridge name alone.
