Sublimation printing is a process of transferring a design onto a garment or substrate using heat and pressure. This process has gained popularity in the textile industry due to its ability to produce vibrant and long-lasting designs. However, sublimation on coloured shirts can be a bit tricky as the dye in the fabric can interfere with the sublimation process. In this article, we will explore how to perform sublimation on coloured shirts and achieve high-quality designs.
Understanding the Sublimation Process
Before we dive into the specifics of sublimation on coloured shirts, let's first understand the sublimation process itself. Sublimation printing involves using a special type of ink that, when heated, turns into a gas and bonds with the fabric's fibers. The result is a permanent, high-quality print that does not crack, peel, or fade over time.
The key to successful sublimation printing is to use the right type of fabric. Sublimation inks work best on fabrics with a high polyester content. This is because the ink bonds more effectively with the polyester fibers than with other types of fibers like cotton. Therefore, when choosing a coloured shirt for sublimation printing, it's essential to make sure it has a high polyester content.
Preparing the Coloured Shirt
The first step in performing sublimation on coloured shirts is to prepare the garment properly. Start by washing the shirt to remove any dirt, oil, or other impurities that could interfere with the sublimation process. Use a mild detergent and avoid using fabric softeners as they can leave a residue on the fabric that could affect the transfer.
Once the shirt is clean, it's essential to ensure it's completely dry before printing. Any moisture on the fabric can cause the ink to run or smudge, ruining the final print. Therefore, it's best to let the shirt air dry or use a dryer on low heat.
Printing the Design
Now that the shirt is prepped and ready, it's time to print the design. When printing on coloured shirts, it's essential to use a white underbase to ensure the colours come out bright and vibrant. The white underbase is printed first, and then the coloured ink is printed on top.
It's crucial to use a sublimation printer and ink for this process. These printers are designed to handle the high temperatures required for sublimation printing and have a special type of ink that turns into a gas when heated.
When printing, ensure the design is aligned correctly on the shirt. Use a heat-resistant tape to hold the transfer paper in place and avoid any movement during the pressing process.
Heat Pressing the Shirt
After printing the design onto the transfer paper, it's time to transfer it onto the shirt using a heat press. The heat press applies high heat and pressure to the transfer paper, causing the ink to turn into a gas and bond with the fabric.
When pressing coloured shirts, it's essential to adjust the temperature and pressure settings accordingly. Since the dye in the fabric can interfere with the sublimation process, it's best to use a lower temperature and higher pressure to ensure a successful transfer.
It's also important to use a Teflon sheet or parchment paper between the transfer paper and the heat press to prevent any ink from sticking to the press.
Conclusion
Sublimation printing on coloured shirts can be a bit tricky, but with the right preparation and equipment, it's possible to achieve high-quality designs. When performing sublimation on coloured shirts, it's essential to use a high-polyester content fabric and a white underbase for the best results. Proper preparation, printing, and pressing techniques are also crucial for achieving vibrant and long-lasting prints.
