What is sublimation printing?
Sublimation printing is a fascinating and innovative technique that has gained popularity across various industries in recent years. From fashion and textiles to personalised gifts and promotional products, sublimation printing can be used to create exciting designs.
This unique printing method offers vibrant, long-lasting, and high-quality results, making it a preferred choice for businesses and individuals seeking to create eye-catching and durable pieces.
In this article, we’ll answer the question of “what is sublimation printing”, while also exploring how it works, its applications, and the advantages it offers.
What is sublimation printing?
So, what is dye sublimation printing? Sublimation printing is a specialised digital printing process that involves the transfer of dye onto a substrate (usually a fabric or a specially coated surface) using a combination of heat and pressure. This ink is heated up until it turns into a gas, which is then transferred onto the textile to display the design.
Unlike traditional printing methods that use liquid ink, sublimation printing uses dye-based inks that have the ability to transform from a solid to a gas state without passing through a liquid phase. This process generally works best on polyester or polyester blend fabrics.
How does sublimation printing work?
The process of dye sublimation printing is relatively straightforward. It’s important to first understand that this form of printing relies on the principle that solid dyes, when exposed to heat and pressure, can transform into a gas and bond with the surface of the substrate. In order for this to occur, the design is first printed onto a special sublimation paper using sublimation inks, with this paper acting as a form of transfer medium.
Once the design has been put on this paper, it is then placed in a heat press machine. Here the ink is heated up, permeating the substrate’s surface. The heat is then removed from the design, allowing the ink to return to a solid state which then bonds permanently with the substrate. This process creates a high-quality, high-resolution print that is not only vibrant and eye-catching, but also durable and long lasting.
Applications of sublimation printing
Sublimation printing is widely used across various industries to create customised products in a range of different materials. This includes:
Apparel and textiles
Sublimation printing is widely used in the apparel industry to create custom t-shirts, hoodies, socks, and more. The prints are long-lasting and resistant to fading, making them ideal for fashion garments.
Home decor and interior design
Sublimation printing is employed to produce vibrant and artistic designs for cushions, curtains, beddings, and other home decor items. It allows for unique customisation and complex patterns that can transform living spaces.
Promotional products
Sublimation printing is extensively used to create personalised promotional items such as mugs, keyrings, and phone cases. The ability to print on curved and irregular surfaces adds versatility to promotional product design.
Signage and banners
Sublimation printing is effective in producing large-format prints for banners, flags, and indoor/outdoor signage due to its ability to maintain image quality and vivid colours over an extended period of time.
Benefits of sublimation printing
There are many different benefits to sublimation printing.
Durability
Sublimation prints are highly durable. This is due to the fact that the ink becomes a part of the substrate’s fabric or coating. The durability of sublimation printing ensures that the design remains vivid and vibrant even after numerous washes or extended exposure to the elements.
Colour reproduction
Sublimation printing offers exceptional colour reproduction and sharpness, enabling the creation of intricate and photorealistic designs that impress and attract attention. However, it’s worth noting that sublimation works best when printing onto lighter colours.
Quick turnaround
Sublimation printing is relatively fast, making it suitable for on-demand production and custom printing services. Often, sublimation printing can be completed on the same day an order is made.
Drawbacks of sublimation printing
While sublimation printing has a number of benefits, it also has a few drawbacks.
Cannot print white
Sadly, there’s no combination of sublimation inks that can be brought together to make the colour white. As such, it’s not possible to produce white in sublimation prints. Sublimation is best printed on white or light-coloured textiles.
Can be expensive
If you’re looking to create large runs of prints, sublimation may not be the most cost-effective method of doing so. However, for those that wish to have high-resolution designs, sublimation printing might still be the best option.
Textiles must be polyester
Sublimation printing can only be done on polyester textiles, which makes it somewhat limiting. As such, if you’re looking to print onto cotton, you’ll likely need to use screen printing or another method.
What type of paper is used for sublimation printing?
Sublimation printing requires a specific kind of transfer paper. This is paper with a special coating that holds the sublimation ink, while also being able to transfer it onto the chosen surface once it’s heated to the required level. As such, regular paper for inkjet printing is unsuitable for sublimation.
Can you use a regular printer for sublimation?
As a general rule, regular inkjet printers cannot be used for sublimation printing. While some with Micro Piezo printing heads may be able to be converted to sublimation printing, doing so will likely void the warranty. Consider this before attempting the conversion.
Sublimation printing offers a versatile and long-lasting solution for creating vibrant and detailed designs on polyester textiles. Its wide range of applications, durability, and vivid colour reproduction make it a preferred choice for businesses and individuals looking to express their creativity and make a lasting impression.
