How To Press Sublimation Shirts?

Understanding Sublimation Printing on Shirts

Sublimation printing is a popular method used to transfer designs onto shirts, resulting in vibrant and long-lasting prints. Unlike traditional screen printing, sublimation involves the use of heat and special dyes that transform directly from a solid to a gas, without passing through a liquid state. This process allows the inks to penetrate the shirt's fabric fibers, resulting in vibrant and permanent designs.

To achieve the best results when pressing sublimation shirts, it is important to follow specific techniques and use suitable equipment. In this article, we will explore the step-by-step process of how to press sublimation shirts, ensuring you achieve professional results each time.

Step 1: Choosing the Right Apparel

The first step in pressing sublimation shirts is selecting the right apparel. For successful sublimation, it is crucial to choose 100% polyester or polyester-coated garments. These fabrics have the ability to absorb and retain the sublimation ink, resulting in vibrant and durable prints.

Avoid using apparel with high cotton content, as cotton fibers resist the sublimation process and won't yield optimal results. Additionally, ensure that the shirts are clean and free from any dirt, lint, or wrinkles before proceeding to the pressing process.

Furthermore, consider the type of shirt you want to press. Different shirt styles, such as t-shirts, polo shirts, or hoodies, may require slight variations in pressing techniques due to differences in fabric weight and thickness.

Step 1.1: Checking Fabric Composition

Before attempting to press a shirt, it is essential to thoroughly check the fabric composition. Most garments will have a tag or label indicating the fabric content. Ensure that it is at least 80-90% polyester for optimal sublimation results. Polyester blends or polyester-coated fabrics are also suitable for sublimation.

Garments with a high cotton content or other natural fibers are not ideal for sublimation printing. The inks used in sublimation cannot penetrate these fibers effectively, resulting in less vibrant and shorter-lasting prints. Therefore, always verify the fabric composition to ensure a successful sublimation process.

In some cases, shirts with a moderate amount of polyester can be used if the manufacturer claims they are suitable for sublimation. However, it is always recommended to perform a test press before proceeding with a larger batch to ensure the desired outcome.

Step 1.2: Preparing the Shirt

Once you have chosen the appropriate apparel, it is crucial to prepare the shirt before pressing. Start by washing and drying the shirt to remove any dirt, dust, or chemicals that may interfere with the sublimation process. Use a mild detergent and avoid fabric softeners, which can create a barrier that prevents the ink from properly adhering to the fabric.

After washing, ensure the shirt is completely dry and free from wrinkles. Wrinkles can interfere with the transfer process and result in an uneven print. Consider using an iron or a garment steamer to remove any stubborn wrinkles before proceeding.

Once the shirt is clean and wrinkle-free, it is ready for the pressing process.

Step 2: Preparing the Design

Before pressing the sublimation shirt, it is essential to have the design ready. The design can be created using various graphic design software, such as Adobe Photoshop or Illustrator. Remember, your design should be a mirror image of how you want it to appear on the shirt.

Once the design is ready, print it using a sublimation printer and sublimation ink on special sublimation paper. The sublimation ink is specifically formulated to convert from a solid to a gas when exposed to heat, allowing it to penetrate the fabric's fibers.

Ensure that the sublimation printer is properly calibrated and the ink is of good quality. Poor calibration or low-quality ink can result in blurry or dull prints.

Step 2.1: Mirror Imaging the Design

When preparing the design for sublimation, it is crucial to mirror or flip the image horizontally. This is because when the design is transferred onto the shirt, it will be reversed. By mirroring the image before printing, you ensure that the final print appears exactly how you intended it to be.

Most graphic design software has a built-in option to mirror or flip the image. Simply select this option before printing to create a mirror image of your design.

Ensure that the mirroring is done correctly, as any text or graphics that should read from left to right will appear reversed if the image is not flipped.

Step 2.2: Cutting the Design

After printing the design, carefully cut around the edges to remove any excess white space or unwanted borders. This will allow for a clean and seamless transfer onto the shirt.

Be cautious not to cut into the design itself or damage any important elements. Take your time and use sharp scissors or a paper cutter for precise cuts.

Once the design is properly cut, it is ready to be transferred onto the sublimation shirt.

Step 3: Heat Pressing the Sublimation Shirt

The heat pressing process is the key step in sublimation printing. It involves using a heat press machine to transfer the sublimation ink from the paper onto the shirt. Follow these steps to ensure a successful heat press:

  • Preheat the heat press machine to the recommended temperature for sublimation, typically around 375°F (190°C).
  • Adjust the pressure of the heat press machine according to the fabric thickness and type of shirt.
  • Place a Teflon sheet or parchment paper on the heat press to protect the shirt from direct heat and prevent ink bleed onto the upper platen.
  • Position the shirt on the heat press, ensuring it is smooth and without any wrinkles.
  • Place the printed design face-down on the shirt, aligning it with the desired position.
  • Cover the design and shirt with another Teflon sheet or parchment paper to create a sandwich-like effect.
  • Close the heat press, applying the recommended pressure and time specified by the sublimation paper manufacturer or equipment instructions.
  • Once the pressing time is complete, carefully open the heat press and lift the upper platen.
  • Remove the Teflon sheet or parchment paper and peel the sublimation paper from the shirt while it is still hot.
  • Allow the shirt to cool completely before handling or wearing.

Step 3.1: Being Mindful of Temperature and Pressure

Temperature and pressure are critical factors in the sublimation heat press process. It is important to adhere to the recommended temperature and pressure settings for sublimation, as high temperatures can result in scorching or burning the fabric, while low temperatures may not activate the sublimation ink effectively.

Similarly, adjusting the pressure of the heat press machine is essential to ensure proper ink transfer. Too much pressure can cause the ink to bleed or distort, while insufficient pressure may result in incomplete transfers.

Refer to the equipment manufacturer's guidelines and the sublimation paper instructions for recommended temperature and pressure settings. Make any necessary adjustments based on your specific equipment and fabric thickness.

Step 4: Post-Pressing Care

Once the sublimation shirt has been heat pressed, it is important to follow proper care instructions to maintain the longevity of the print. Consider the following post-pressing care tips:

  • Allow the shirt to cool completely before handling or folding to prevent any potential damage to the print.
  • Wash the shirt inside out in cold water with like colors, using a mild detergent. Avoid bleach or any harsh chemical detergents.
  • Avoid tumble-drying the shirt or exposing it to high heat as it can fade the sublimation print. Instead, hang or lay flat to air dry.
  • Avoid ironing directly on the sublimated area, even if the shirt requires ironing. Use a pressing cloth or iron on the reverse side of the print.
  • Store the shirt flat or folded neatly to prevent any creases or damage to the print.

Following these care instructions will help maintain the quality and vibrancy of the sublimation print, ensuring it lasts for a long time.
