The choice between gloss and matte printable magnetic paper will often depend on the desired appearance of the finished magnetic graphic.

White gloss printable magnetic paper provides:

• A glossy appearance
• More surface shine
• A bright presentation for photographs and graphics
• A suitable surface for promotional and display applications

Matte printable magnetic paper provides:

• A non-glossy appearance
• Reduced surface reflections

Potential applications include:

• Promotional messages
• Product information
• Price displays
• Seasonal campaigns
• Sale signage
• Display graphics
• Stock information
• Temporary promotions

Where the display surface is compatible ferromagnetic steel, magnetic graphics can be removed, replaced and repositioned as promotions change.

The sheets can also be cut into smaller words, numbers, shapes or graphics for appropriately supervised classroom activities.

Cutting A3 Printable Magnetic Paper

These flexible magnetic sheets can be cut into smaller pieces or custom shapes where appropriate.

One 420mm x 297mm A3 sheet can potentially be divided into multiple:

• Magnetic labels
• Photos
• Promotional magnets
• Signs
• Decorative shapes
• Educational pieces
• Custom graphics

Planning the artwork layout before printing and cutting can help maximise the usable area of each sheet.

Always use suitable cutting equipment and follow appropriate cutting-tool safety procedures.

Printer Compatibility

Printers vary significantly in the types and thicknesses of media they can safely process.

Before printing, confirm that your printer can accommodate both the A3 sheet size and 0.3mm magnetic media thickness.

Check the printer manufacturer's specifications regarding:

• A3 media support
• Maximum media thickness
• Supported media types
• Paper path
• Sheet feeding
• Print settings
• Printable surfaces

The specific printer technology compatibility and recommended printer settings have not been supplied for this product and should not be assumed.

Where practical, test one sheet and confirm satisfactory feeding and printing before producing the complete project.

Compatible Magnetic Surfaces

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

• Mild steel
• Iron
• Magnetic steel
• Compatible steel cabinets
• Steel shelving and racking
• Suitable steel display 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 are also weakly magnetic or non-magnetic. Test the intended surface before relying on magnetic attachment.

Not Compatible with Glassboards

Glassboards create a physical gap between flexible magnetic material and any ferromagnetic backing behind the glass. Thin flexible magnetic products generally do not provide sufficient attraction across this distance.

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

For glassboard applications, use magnets specifically designed to provide sufficient magnetic attraction through the glass surface.

Magnetic Performance

This 0.3mm printable magnetic paper is designed primarily for lightweight printed magnetic applications rather than high-force magnetic holding.

Practical magnetic performance depends on factors including:

• Magnetic sheet thickness
• Size of the finished magnetic piece
• Available contact area
• Target steel composition
• Target steel thickness
• Surface flatness
• Paint and coatings
• Air gaps
• Surface condition
• Installation orientation

No specific pull force or magnetic flux density in Gauss has been supplied for this product and these values should not be assumed.

Surface Area and Magnetic Holding

The amount of magnetic material contacting the target surface can significantly influence practical holding performance.

A complete A3 sheet provides a large magnetic contact area, while a small piece cut from the same sheet has substantially less magnetic material in contact with the target surface.

When creating smaller magnetic pieces, consider:

• Finished dimensions
• Weight of the printed piece
• Available contact area
• Target material
• Surface coatings
• Installation orientation

Testing the finished magnetic graphic on its intended surface is recommended.

Printable Magnetic Paper vs Rigid Magnets

Printable magnetic paper is designed for a different purpose from conventional rigid permanent magnets.

Printable magnetic paper is particularly useful for:

• Custom printing
• Photographs
• Signs
• Labels
• Calendars
• Promotional graphics
• Large-format displays
• Custom-cut magnetic products

Rigid neodymium magnets generally provide substantially greater magnetic performance relative to their physical size and are more appropriate for concentrated holding applications.

This 0.3mm A3 magnetic paper is therefore generally selected for printability, flexibility, large printable area and lightweight display applications rather than maximum magnetic strength.

Permanent Magnetic Operation

These printable magnetic sheets use permanent magnetic material.

They require:

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

The flexible magnetic backing remains continuously magnetic during normal use.
