Creating custom sublimation magnets is one of the fastest ways to turn photos, artwork, or brand graphics into profitable, high-margin products for home, office, and promotional use. This guide walks through everything from artwork setup and heat press settings to troubleshooting, safety, and equipment recommendations, so you can achieve vivid, durable results on every press.
Sublimation magnets are hardboard or metal blanks with a white polyester coating that permanently bonds with sublimation ink when heated under pressure. After pressing, the ink becomes part of the coating, producing a scratch-resistant and fade-resistant full-color image.
Because the magnet strip is usually applied after pressing, the magnetic layer is protected from high heat, which improves durability and reduces warping or bubbling. Sublimation magnets are widely used for photo gifts, souvenir sets, branding giveaways, and limited-edition artist collections.
Using sublimation for magnets offers several advantages over stickers, laminated prints, or basic printed magnets.
- High-resolution, photo-quality color that covers the entire coated surface edge-to-edge.
- Permanent image that will not peel, crack, or wash off under normal use.
- Fast production cycle; many makers press a full batch of magnets in just a few minutes.
- Low material cost per piece, making magnets ideal for e-commerce bundles or event giveaways.
For shops already running a heat press, adding sublimation magnets is an easy product extension with minimal additional equipment.
To produce custom sublimation magnets consistently, gather the following core tools and materials.
- Sublimation printer and ink: Dedicated sublimation printers deliver stable, vivid color output.
- Sublimation paper: Use high-quality paper that matches your printer profile for accurate color and sharp details.
- Heat press machine: A flat heat press with precise time, temperature, and pressure control is essential for repeatable results.
- Sublimation magnet blanks: Typically hardboard or metal panels with separate adhesive magnet pieces.
- Heat-resistant tape: Keeps your transfer aligned and prevents ghosting during pressing.
- Protective sheets: Parchment or butcher paper above and below the transfer protects the platen from ink blowout.
For higher-volume workflows, professional presses with even heat distribution and digital controls help maintain consistent quality across large batches.
Correct artwork setup is critical for clean edges and accurate placement on small magnet surfaces.
- Download or create a magnet template that matches the exact printable area of your blank, including bleed.
- Import your photos or graphics into design software and scale them slightly larger than the finished size to allow full-bleed coverage.
- Use a clipping mask or shape layer to preview the final crop and ensure important content is not too close to the edges.
For multiple magnets, duplicate the design or lay out several different images on one page to maximize each print sheet and reduce waste.
Once your layout is ready, configure your printer for sublimation magnet production.
- Select the correct substrate type, typically “Polyester” or “Hard Surface,” to match coated blanks.
- Choose the sublimation paper profile recommended by the paper manufacturer for consistent color transfer.
- Enable mirror printing so the design faces correctly when flipped onto the magnet blank.
For images with rich color or photography, use a Photographic or Vivid color mode to preserve gradients and saturation while still maintaining neutral grays.
Different magnet blanks may require slightly different settings, but most hard surface sublimation magnets fall within similar ranges.
- Typical temperature: 375–400°F (about 190–205°C).
- Typical time: 60–80 seconds for single magnets, with a few additional seconds per extra blank in the same press.
- Pressure: Medium to firm, ensuring even contact across all corners of each magnet blank.
Always check the manufacturer's instructions for your specific magnets first, then fine-tune time and pressure if you observe fading, under-transfer, or surface scorching.
Follow this practical workflow to produce custom sublimation magnets with consistent, professional results.
- Prepare the design
Open your template and place the artwork inside the imprint area with bleed.
Duplicate the design if making multiple magnets per sheet.
- Print the transfer
Send the file to your sublimation printer using the correct media profile and mirrored output.
Allow the print to dry fully to prevent smudging and color shifts.
- Pre-press setup
Preheat the heat press to the recommended temperature, for example around 400°F for many hardboard magnets.
Place a sheet of parchment or butcher paper on the lower platen as a protective barrier.
- Prepare the blanks
Peel away any protective film from the white coated side of the magnet blank.
Position the blank white side down onto the printed image so the coated surface contacts the ink.
- Secure with heat tape
Apply heat-resistant tape at the edges to hold the blank firmly in place and prevent shifting during pressing.
- Press the magnets
Flip the assembly so the paper faces up, then place it on the press with protective paper below and above.
Close the press with medium pressure and press for the specified time.
- Cool and peel
After pressing, open the press and allow the blanks to cool for about 30–60 seconds before handling.
Carefully peel the magnet blank away from the transfer; the print should now appear vivid and fully transferred.
- Apply the magnet backing
Once the printed panel is completely cool, attach the adhesive magnet strip or backing to the rear surface.
Press firmly to ensure full adhesion, especially around the edges and corners.
This process allows you to turn a single print sheet into a batch of high-quality magnets ready for packaging or display.
For workshops that produce magnets regularly, investing in a professional sublimation heat press improves efficiency and consistency.
Look for a press with:
- Even heat distribution across the entire platen, preventing hot or cold spots that cause uneven color.
- Digital temperature and time controls that maintain stable settings across long production runs.
- Strong, adjustable pressure suitable for hard-surface blanks that require firm contact.
Swing-away presses are especially helpful because they provide full access to the platen for precise placement while keeping the heated platen away from your hands during setup.
Once the basic process is dialed in, many makers move quickly into batch production for online orders or wholesale clients.
- Arrange multiple blanks on a single large transfer sheet to minimize handling and press cycles.
- When pressing several magnets at once, add a few seconds per additional blank as recommended by your blank supplier to ensure complete transfer.
- Keep a simple production checklist, such as film removal, taping, and protective sheets, to avoid skipped steps when working at speed.
Batch workflows reduce unit cost and help you maintain consistent quality across sets, such as coordinated refrigerator magnet collections or branded promotional series.
Even experienced sublimators occasionally encounter issues; understanding the causes helps you fix them quickly.
- Faded or washed-out images
Possible causes include low temperature, short press time, or incorrect substrate setting in the print manager.
Increase time slightly, verify correct press temperature with a thermometer, and confirm the correct substrate preset is selected.
- Blurry or ghosted edges
Commonly caused by the blank shifting during pressing or insufficient tape.
Use more heat-resistant tape and avoid opening the press early or moving the stack while still hot.
- Yellowing or brown spots
Usually the result of over-pressing at too high temperature or excessive time.
Reduce temperature or time in small steps and always follow the blank manufacturer's recommendations.
Keeping a log of test settings for each blank type helps lock in reliable parameters for future orders.
Running a clean, safe sublimation workspace protects both your equipment and your team.
- Always use heat-resistant gloves when handling freshly pressed magnets or repositioning hot blanks.
- Replace protective paper regularly to prevent ink transfer onto the platen or onto future projects.
- Periodically check your heat press for even pressure and accurate temperature to avoid inconsistent results across batches.
A well-maintained press and clean working environment reduce misprints and keep production predictable and efficient.
Custom sublimation magnets can be marketed in many high-value product formats across B2C and B2B channels.

Most hard surface sublimation magnets press well between 375–400°F for about 60–80 seconds, but you should always confirm the exact settings from your blank supplier.
Regular inkjet printers are not suitable; you need a dedicated sublimation printer with sublimation ink and compatible paper to achieve permanent, full-color transfers on coated magnet blanks.
Faded or dull results are often caused by low temperature, short press time, incorrect substrate settings, or low-quality paper, so adjusting these variables usually restores proper color density.
Sublimation prints are durable and resistant to peeling, but prolonged UV exposure and harsh weather can still cause fading over time, so outdoor use is best limited or combined with UV-resistant coatings.
Secure the blank firmly with heat-resistant tape, avoid shifting the stack while hot, and do not open and re-close the press mid-cycle, which are common causes of ghosting and blurred edges.
