What is Sublimation Printing?
What is Sublimation Printing? Sublimation printing is a popular method of printing that uses heat to transfer dye onto materials such as fabric, ceramics, metal, and other specially coated surfaces. The technology is widely used to create high quality full colour prints on a variety of items such as t-shirts, mugs, phone cases and banners. Here is a detailed description of how heat sublimation printing works and its benefits.
How Does Sublimation Printing Work?
Sublimation printing involves a few key steps:
Design Creation: The process begins with the creation of a digital design using software such as Adobe Photoshop, Illustrator or CorelDRAW. The design can include full-colour images, text or patterns.
Printing the Design: Once the design is complete, it is printed onto special thermal sublimation paper using thermal sublimation inks. These inks are different from regular inks because they turn to gas when heated.
Heat Transfer Process: The printed design on the heat sublimation paper is placed onto the item to be printed, such as a T-shirt or mug. A heat press is then used to apply pressure and heat (usually between 350°F and 400°F) for a specific period of time.
Sublimation and Bonding: At high temperatures and pressures, sublimation ink becomes a gas without passing through the liquid phase (hence the term ‘sublimation’). The gas penetrates the surface of the item and solidifies into the material, becoming a part of it rather than just sitting on top. This produces a permanent, full-colour image that will not fade, crack or peel over time.
What Materials Can Be Used in Sublimation Printing?
Heat sublimation printing is best suited for polyester fabrics or items with special polymer coatings. Below is a breakdown of commonly used materials:
Textiles: Polyester fibres are ideally suited to heat sublimation printing. The process is suitable for items such as T-shirts, sweatshirts and flags.
Ceramics: Mugs, plates and tiles can be heat sublimation printed if they have a special polymer coating that allows the dye to bond to the surface.
Metals: Printing can be done on aluminium plates, key fobs and other metal items, provided they have a heat sublimation coating.
Plastics: Certain types of plastics, such as those used for mobile phone cases and name tags, are also suitable for heat sublimation printing.
Benefits of Sublimation Printing
Sublimation printing offers several advantages:
Vibrant Colours: Because the dye becomes part of the material, heat sublimation printing produces exceptionally vibrant, full-colour images with crisp detail.
Durability: Printed designs are permanent and will not fade, flake or crack over time, even after multiple washes or heavy use.
Full-Face Printing: Heat sublimation allows for edge-to-edge printing, which is perfect for creating full-face designs on t-shirts or large banners.
Soft Touch: Because the dye is embedded in the fabric rather than resting on the surface of the fabric, there is no additional texture to a heat sublimation print, making the fabric feel as soft as it did before printing.
Limitations of Sublimation Printing
While sublimation printing has many benefits, there are a few limitations:
Material Limitations: Thermal sublimation printing is primarily for polyester or polymer coated materials, which may limit the types of items you can print.
Colour Limitations: Thermosublimation is best suited to white or light coloured materials. Darker colours do not show the sublimation colours well as the ink is translucent.
Initial Setup Costs: Thermal sublimation printers and heat presses can cost more compared to standard inkjet or laser printers.
Common Uses of Sublimation Printing
Sublimation printing is widely used in various industries, including:
Clothing: Customised T-shirts, sweatshirts and other clothing.
Promotional Products: items such as mugs, mouse pads and mobile phone cases.
Home Décor: personalised cushions, curtains and wall art.
Corporate Branding: branded items such as lanyards, name tags and banners.
Conclusion
Heat sublimation printing is a versatile and durable method that is perfect for creating vibrant, long-lasting prints on a variety of polyester-based or polymer-coated items. Whether you are producing bespoke clothing, promotional items or personalised gifts, heat sublimation printing offers a high quality solution to ensure your designs stand out and last.
