Printer Compatibility

Printer technology and printer settings have not been specified for this magnetic paper.

Before printing, check the printer manufacturer's specifications to confirm that the printer can safely accept:

• A3-sized media
• 0.3mm thick media
• Flexible magnetic printing material
• The required media feed path

Do not assume that a printer can process magnetic paper simply because it accepts standard A3 paper.

Where practical, test a single sheet before beginning a larger print run and follow the printer manufacturer's recommended media handling and settings.

This is particularly important with a 50-sheet bulk pack where multiple sheets may be printed as part of the same project.

Compatible Magnetic Surfaces

The flexible magnetic backing is designed to attach to suitable ferromagnetic surfaces, including:

• Mild steel
• Iron
• Magnetic steel
• Compatible steel cabinets
• Steel shelving
• Steel storage systems
• Suitable appliances
• Magnetic notice surfaces

It will not effectively attach magnetically to inherently non-magnetic materials such as:

• Aluminium
• Copper
• Brass
• Plastic
• Timber
• Standard glass

Many stainless steel grades may also be weakly magnetic or non-magnetic and should be tested before relying on magnetic attachment.

Not Compatible with Glassboards

Glassboards generally position a layer of glass between the flexible magnetic material and the underlying steel or magnetic component.

This additional distance substantially reduces the effectiveness of flexible magnetic products.

Please note, this product alongside all flexible magnetic products are not compatible with glassboards.

For glassboard applications, use magnetic products specifically designed and rated for use through the glass surface.

Magnetic Performance

Printable magnetic paper is designed primarily for lightweight magnetic display, signage, promotional and identification applications.

It should not be compared directly with rigid neodymium, ferrite, Alnico or Samarium Cobalt magnets designed for concentrated or higher-force magnetic holding.

Practical magnetic attachment depends on factors including:

• Available magnetic surface area
• Target steel composition
• Target steel thickness
• Surface flatness
• Paint and coatings
• Air gaps
• Curvature
• Installation orientation
• Weight of the finished printed sheet

No specific pull force or magnetic flux density in Gauss has been supplied for this product.

Surface Area and Magnetic Holding

Flexible magnetic materials generally benefit from having a larger magnetic surface area in direct contact with compatible steel.

A complete A3 sheet provides a large contact area when positioned flat against a suitable target.

If the material is cut into smaller pieces, each piece has less magnetic surface area available for attachment.

Use sufficient magnetic surface area for the size, weight and orientation of the finished magnetic graphic.

Air Gaps and Surface Contact

For best practical magnetic attachment, maximise direct contact between the magnetic backing and target steel.

Performance can be reduced by:

• Thick paint
• Powder coating
• Protective films
• Dirt
• Dust
• Rust
• Curved surfaces
• Uneven surfaces
• Material positioned between the magnetic backing and steel

Clean, flat contact generally provides better magnetic attachment.

Flexible Magnetic Paper vs Rigid Magnets

Printable magnetic paper serves a different purpose from rigid permanent magnets.

Flexible printable magnetic paper is particularly suitable for:

• Printed graphics
• Photos
• Signs
• Labels
• Promotional material
• Lightweight displays

Rigid permanent magnets, including neodymium and ferrite magnets, are generally more appropriate for:

• Higher-force holding
• Mechanical assemblies
• Fixtures
• Magnetic closures
• Industrial magnetic systems

This 0.3mm magnetic paper should therefore be considered lightweight flexible magnetic display media, rather than a high-strength holding magnet.

Permanent Magnetic Operation

The flexible magnetic backing is permanently magnetic during normal use.

It requires:

• No electricity
• No batteries
• No charging
• No external power supply

Once printed, position the magnetic backing against a compatible ferromagnetic surface.

Storage and Handling

To help preserve the condition of the magnetic sheets:

• Store sheets flat where possible
• Keep the material clean and dry
• Protect the printable face from scratching
• Avoid sharp folds and permanent creases
• Keep unused sheets protected from dust and contamination
• Avoid excessive heat unless temperature suitability has been confirmed
• Follow printer manufacturer instructions during printing

Permanent creases may affect both the appearance of the finished graphic and the amount of magnetic surface that sits flat against the target.

For bulk storage, keep the unused sheets supported and protected so the edges and printable surfaces remain in good condition.
