Printer Compatibility

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

Before printing, check your printer manufacturer's specifications to confirm that it 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 first and use media handling and settings recommended by the printer manufacturer.

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 can also be weakly magnetic or non-magnetic and should be tested before relying on magnetic attachment.

Not Compatible with Glassboards

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

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

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 display, signage, promotional and identification applications.

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

Practical attachment depends on:

• 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.

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 surface.

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

Use sufficient magnetic surface area for the dimensions, weight and orientation of the finished 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 useful for:

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

Rigid 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, simply position the magnetic backing against a compatible ferromagnetic surface.
