5 Individual A3 Magnetic Sheets

This pack contains 5 individual sheets of A3 printable magnetic paper.

Each sheet measures:

• 420mm long
• 297mm wide
• 0.3mm thick

The 5-pack is a practical option for small production runs, one-off projects, multiple designs or testing different graphics without purchasing a larger bulk pack.

The sheets can be used individually for full-size A3 graphics or divided into smaller magnetic pieces where suitable for the intended application.

Large A3 Printable Magnetic Paper

A3 provides a substantially larger printable area than standard A4 media.

At 420mm x 297mm, an A3 sheet has approximately twice the surface area of an A4 sheet.

This makes A3 magnetic paper useful for applications such as:

• Larger promotional graphics
• Retail signage
• Information displays
• Event graphics
• Educational diagrams
• Large photographs
• Magnetic notices
• Custom visual displays

For smaller magnets, the sheet may also be cut into multiple individual pieces after printing where appropriate.

White Gloss Printable Face

The printable face has a white gloss finish, providing a smooth, reflective surface for printed graphics.

A gloss finish can be useful where a polished visual appearance is preferred for:

• Photographs
• Promotional graphics
• Retail displays
• Branding
• Marketing materials
• Decorative designs

The white surface provides a neutral base for printed artwork, text and images.

Actual print appearance will depend on the printer, ink or toner system, artwork, print settings and compatibility between the printer and magnetic media.

Gloss vs Matte Magnetic Paper

Gloss and matte printable magnetic papers provide different visual finishes.

White gloss magnetic paper provides:

• A shinier surface
• Greater surface reflection
• A polished visual appearance
• Suitability for photos and promotional graphics

Matte magnetic paper provides:

• A non-glossy appearance
• Reduced surface reflection
• A more subdued finish

The preferred finish depends on the intended appearance, lighting conditions and application.

Printer Compatibility

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

Before printing, confirm that your printer can safely accept:

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

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

Where possible, test a single sheet before printing a complete project or 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

Printable magnetic paper allows artwork to be turned into a removable magnetic display without permanently fixing the graphic to the target steel surface.

Potential designs include:

• Logos
• Product information
• Photographs
• Promotional messages
• Instructions
• Calendars
• Educational graphics
• Labels
• Event information
• Decorative artwork

This makes the sheets useful where graphics need to be changed, repositioned or removed.

Retail and Promotional Displays

A3 printable magnetic sheets can be useful for retail environments where promotional material changes regularly.

Potential applications include:

• Sale signage
• Product promotions
• Pricing displays
• Seasonal graphics
• Brand messaging
• Information panels
• Temporary campaigns
• Point-of-sale material

When applied to a suitable steel surface, magnetic graphics can be removed without the permanent attachment associated with many adhesives.

Business and Office Applications

Printable magnetic paper can also be used to create custom workplace materials.

Examples include:

• Magnetic notices
• Workflow information
• Staff information
• Equipment labels
• Calendars
• Schedules
• Visual management graphics
• Temporary instructions

The A3 format provides useful space for information that needs to remain visible from a greater distance than smaller labels.

Educational and Classroom Applications

A3 magnetic paper can be used to create reusable educational resources for suitable magnetic surfaces.

Potential applications include:

• Diagrams
• Maps
• Charts
• Timelines
• Learning activities
• Classroom signs
• Visual aids
• Teaching graphics

The magnetic backing allows resources to be repositioned as lessons and activities change.

Events and Exhibitions

The combination of a printable surface and magnetic backing can be useful for temporary displays where compatible steel structures or panels are available.

Potential applications include:

• Event signage
• Exhibition graphics
• Promotional displays
• Directional information
• Temporary branding
• Information panels

Always confirm that the intended display surface is sufficiently ferromagnetic before preparing the finished graphics.

Cut Into Smaller Magnetic Pieces

The A3 sheets can be used whole or cut into smaller pieces where appropriate.

A single sheet may therefore be used to create:

• Multiple labels
• Small promotional magnets
• Individual photographs
• Product markers
• Name labels
• Custom shapes
• Craft magnets

When cutting, use suitable equipment and ensure edges are clean for the intended application.

Flexible 0.3mm Profile

At 0.3mm thick, this magnetic paper is designed as a thin, flexible magnetic display material rather than a rigid permanent magnet.

Its slim profile can be useful where:

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

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

Designed for Lightweight Magnetic Display

Printable magnetic paper is intended primarily for lightweight display applications.

It should not be treated as:

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

The 0.3mm thickness describes the physical thickness of the sheet and does not indicate a particular pull force.

Magnetic Holding and Surface Area

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

A larger magnetic graphic can have more available contact area than a very small piece cut from the same material.

Practical holding can depend on:

• Contact area
• Target material
• Target steel thickness
• Surface flatness
• Surface condition
• Paint and coatings
• Air gaps
• Size and shape of the finished piece

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, compatible ferromagnetic surface.

Holding can be reduced by separation caused by:

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

Keeping the magnetic backing flat against the target helps maximise available 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 Graphics

One of the advantages of magnetic graphics is that they can be removed or repositioned without relying on permanent adhesive attachment to the target surface.

This makes printable magnetic paper useful for information or graphics that change regularly, including:

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

Always ensure the target surface is compatible with flexible magnetic material.

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.

Please Note

This pack contains 5 individual A3 White Gloss Printable Magnetic Paper sheets, each measuring 420mm x 297mm x 0.3mm thick.

Printer technology and specific printer compatibility have not been supplied. Before use, confirm that your printer supports A3-size, 0.3mm thick flexible magnetic media, including the appropriate feed path and media settings. Testing a single sheet before a complete print run is recommended.

No specific pull force, Gauss rating, magnetic material grade, dimensional tolerance, maximum operating temperature or environmental rating has been supplied and these specifications should not be assumed.

This product is designed primarily for lightweight printable magnetic graphics and displays, not high-force holding, structural mounting or lifting applications. Practical holding depends on the size of the finished magnetic piece, available surface area, target material, target steel thickness, surface condition and air gaps.

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