Printer Compatibility

Specific printer technology and printer compatibility have not been supplied for this magnetic paper and should not be assumed.

Before printing, confirm that your printer is designed to accept:

• A3 media measuring 420mm x 297mm
• 0.3mm thick flexible magnetic media
• The relevant media weight and flexibility
• The required feed path

Check the printer manufacturer's instructions for supported media types, maximum media thickness, feed requirements and recommended settings.

Where possible, test a single sheet before printing the complete 25-sheet production run.

Do not force magnetic media through a printer that is not designed to accept its thickness or material type.

Create Custom Magnetic Graphics

• Labels
• Event information
• Decorative artwork

This makes the material useful where graphics need to be changed or repositioned without permanently attaching them to the target steel surface.

Retail and Point-of-Sale Displays

The 25-pack is particularly useful for retail and commercial environments where multiple promotional graphics may be required.

Potential applications include:

• Sale signs
• Product promotions
• Pricing displays
• Seasonal campaigns
• Brand graphics

This can make a 25-sheet pack useful for producing a large number of smaller magnetic items.

Use suitable cutting equipment and ensure finished edges are appropriate for the intended application.

Flexible 0.3mm Profile

At 0.3mm thick, this printable magnetic paper is designed as a thin and flexible display material rather than a rigid high-strength magnet.

Its slim profile can be useful where:

• Lightweight graphics are required
• A flexible magnetic sheet is preferred
• Low-profile displays are desirable
• The graphic needs to sit close to a flat steel surface

This product should not be directly compared with rigid ferrite or neodymium magnets, which are intended for substantially different magnetic applications.

Designed for Lightweight Magnetic Display

Printable magnetic paper is primarily intended for lightweight magnetic graphics and displays.

It should not be used as:

• A structural magnetic mounting system
• A high-force holding magnet
• A safety restraint
• A load-bearing attachment
• A lifting magnet

The 0.3mm thickness is a physical dimension and does not represent magnetic pull force or holding capacity.

Surface Area and Magnetic Holding

Flexible magnetic materials generally perform best when a substantial area of the magnetic backing is in direct contact with a suitable ferromagnetic surface.

Practical holding can depend on:

• Size of the finished graphic
• Available magnetic surface area
• Target material
• Target steel thickness
• Surface flatness
• Paint and coatings
• Air gaps
• Surface cleanliness

A large A3 magnetic graphic provides considerably more contact area than a small piece cut from the same sheet.

Where holding performance is important, test the finished magnetic graphic on the actual intended surface.

Air Gaps and Surface Condition

Flexible magnetic paper generally performs best when positioned flat against a clean ferromagnetic target.

Magnetic attraction can be reduced by separation caused by:

• Thick paint
• Surface coatings
• Dirt
• Dust
• Rust
• Uneven surfaces
• Non-magnetic layers

Keeping the magnetic backing flat and close to the target surface helps maximise available magnetic contact.

Compatible Magnetic Surfaces

This printable magnetic paper is designed to attach to suitable ferromagnetic materials, including:

• Mild steel
• Iron
• Magnetic steel
• Compatible steel panels
• Suitable magnetic display surfaces

It will not magnetically attach 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 and should be tested before relying on magnetic attachment.

Removable and Repositionable Displays

A key benefit of magnetic graphics is their ability to be removed and repositioned on compatible steel surfaces.

This makes printable magnetic paper useful for frequently changing information such as:

• Promotions
• Prices
• Schedules
• Seasonal messages
• Event information
• Classroom materials
• Temporary signage
• Workplace notices

Unlike permanent adhesive graphics, the magnetic backing does not require adhesive attachment to the target steel surface.

Permanent Magnetic Operation

The flexible magnetic backing is a permanent magnetic material.

It requires:

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

The magnetic backing remains active during normal use.
