These metal blanks come in various shapes and sizes, allowing for endless possibilities when it comes to creating personalized products.

Sublimation Printer

A sublimation printer uses special inks that can turn into a gas when exposed to high temperatures, allowing for the image to transfer onto the metal surface. These printers are specifically designed for sublimation and are essential for achieving professional-quality results.

Sublimation Ink

Sublimation inks are not your regular printing ink. They consist of special dyes that transform into gas when heated, bonding with the metal surface. These inks are available in various colors, including CMYK (Cyan, Magenta, Yellow, and Black), allowing for a wide range of hues to be produced.

Heat Press

A heat press is an essential tool for sublimating metal. This device uses high temperatures and pressure to transfer the image from the paper onto the metal surface. It is crucial to have a heat press that is specifically designed for sublimation, as it needs to reach high temperatures and evenly distribute pressure for the best results.

Transfer Paper

Transfer paper (also known as sublimation paper) is used to transfer the image from the sublimation printer onto the metal surface. This special paper allows the ink to turn into a gas and bond with the metal surface when exposed to high temperatures.

Protective Coating

To ensure that your sublimated image stays vibrant and durable, it is essential to apply a protective coating. This clear coat protects the image from scratches, UV rays, and other environmental factors, ensuring that it stands the test of time.

10 Step-by-step Guidelines on How to Sublimate on Metal

Step 1: Preparing Metal Surfaces for Sublimation

Before starting the sublimation process, it is crucial to prepare the metal surface properly. Begin by cleaning it with a lint-free cloth and rubbing alcohol to remove any dirt, oils, or fingerprints that may affect the transfer.

It is essential to handle the metal surface with gloves to prevent any oils from transferring onto the surface. You can also use a lint roller to ensure that the surface is completely clean. The surface must be free of any scratches, dents, or imperfections that may affect the final result.

Step 2: Printing Your Design

Using sublimation-specific inks, print your desired design onto transfer paper. Make sure to mirror the image before printing, as it will be transferred onto the metal surface in reverse. You can use any design or image software, such as Adobe Photoshop or CorelDRAW, to create and edit your design.

It is essential to use the correct color profile and printer settings for the best results. You can also print multiple designs on one sheet to save transfer paper and time. The design should be slightly larger than the metal surface to ensure complete coverage.

Step 3: Preparing the Heat Press

While your design is printing, you can start preparing your heat press. Set the temperature to 375-400°F (190-204°C) and the pressure to medium. It is essential to refer to the manufacturer’s instructions for specific settings depending on the type of metal and coating used.

The heat press should also be clean and free of any debris that may affect the transfer. It is recommended to use a Teflon sheet on the bottom platen for protection and to avoid any sticking. You can also use a silicone pad for added pressure if needed.

Step 4: Preparing the Metal Surface for Sublimation

Place a sheet of protective paper onto the heat press, followed by your clean and dry metal surface. Make sure to position it correctly with the desired side facing up.

The metal surface should be slightly larger than the transfer paper to avoid any ink from transferring onto the heat press. It is essential to avoid any wrinkles or bubbles on the surface for a smooth transfer. But don’t worry; small imperfections can be fixed later. The metal surface should also be preheated for a few seconds to remove any moisture.

Step 5: Applying the Transfer Paper

Place your printed transfer paper onto the metal surface with the design facing down. The ink should be in direct contact with the metal surface. Again, make sure there are no wrinkles or bubbles for a smooth transfer.

You can use heat-resistant tape to secure the edges of the transfer paper onto the metal surface, ensuring that it doesn’t shift during the transfer process. The tape should be placed on the edges of the design, not covering it. It is crucial to use heat-resistant tape to avoid any melting or transfer onto the metal surface. If you need to use multiple sheets of transfer paper, make sure they are aligned correctly to create a seamless design.

Step 6: Applying Heat and Pressure

Once everything is in place, it’s time to apply heat and pressure using your prepared heat press. Close the lid and set the timer for 60-90 seconds, depending on the size of your design.

It is essential to avoid opening the heat press during this time to ensure an even transfer and avoid any shifting of the design. The pressure should also be evenly distributed for a smooth and vibrant result. The heat press will emit a sound or indicator once the transfer is complete.

Step 7: Removing the Transfer Paper

Once the timer goes off, carefully open the heat press and remove the transfer paper. Make sure to use heat-resistant gloves, as the metal surface will be hot. Place the transfer paper in a safe place and let the metal surface cool down for a few minutes. You can use a heat-resistant spatula to help remove the transfer paper if it is stuck or has any wrinkles. But be gentle to avoid damaging the design.
