No, it isn’t an underwater warship or on-screen translations that help you understand a foreign film; it’s a high-tech printing process for apparel (and a bunch of other stuff!) Today we’re going to pick it apart – we’ll cover what it is, how it works, discuss the pros and cons, when to use it – and when not to.
Let’s start with the broad strokes. What exactly issublimation?
In simple terms, it’s a method of printing that transfers a design intoa material or fabric using ink and heat.
In the world of apparel, it’s a game changer in that it allows whole garmentprints – designs that go seam-to-seam.
So how does it work? Well, sublimation printing uses heat to essentially bring ink and fabric together as one (how philosophical is that?)
First, a design is printed onto special paper. The inks that are used turn into gas when brought under heat, then combine with the fabric and permanently print onto the fabric. The effects are permanent and less prone to fading, as the ink is embedded in the fabric or substrate rather than simply laying on top like a normal print.
The process is almost like a tattoo, but instead of for your skin, it’s for your chosen product. The heat opens up the pores of the fabric, then with the applied pressure the ink cools and returns to a solid form.
The result is a permanent, full colour image that won’t crack, peel or wash away from the substrate, the process allows the ink to go from a solid to a gas without turning to liquid, a bit like dry ice, the conversion is initiated by the heat and controlled by pressure.
This quick and effective digital print method is growing in popularity for smaller batch orders and those designs that rely on the details. The process is also known as ‘all over printing’ as it allows you to choose a design that can literally go from seam to seam.
Although popular in T- shirt printing, the method is also available on ceramic, wood and metals etc, that have a special coating on to receive the sublimation inks.
The most exciting upside when it comes to this method is purely the freedom you have with your designs, which is not always offered by other methods.
On one side of the spectrum you can go as crazy as you like. Why notprint a whole T-shirt that looks like a burger? Or a cat flying across (a beautifully printed) galaxy background?
Equally, you might want to keep it classy with a photo of a famous skyline or landscape. The possibilities are almost endless, which will keep you coming back for more.
The longevity of the design is a plus point, with a design that won’t crack, peel or fade. Even after going through the washing machine countless times, your garment will never be demoted to the back of your wardrobe!
The Cons lay mostly with the choice of materials. Sublimation printing is only suitable for garments that include polyester (100% polyester or polyester blend). Although sublimation is possible on other materials such as cotton, the image will not be permanent as it is on ‘man made’ fabric and it isn’t recommended.
If you wanted to go for the vintage/distressed look, which is all the rage right now, choosing a fabric with a lower percentage of polyester in it would give you that finish.
Another potential problem to watch out for is white creasing. Sublimation works by printing a design into white fabric, and if there are areas of the garment that are unreached by the design, they’ll stay white. This can be caused by accidental folding or small amounts of moisture that accumulate on the transfer paper.
Designs that work well with Sublimation printing
The method works particularly well on quirky, dramatic and almost ridiculous designs- a massive trend over that last couple of years, seen in both high and low end stores.
Now this T-shirt probably fits under quirky, dramatic AND ridiculous, and sublimation printing has allowed for the full effect to take place. The T-shirt is completely covered by design and uses a vibrant range of colours.
The repeated design below also works well, again because of the full coverage aspect of the design, the pattern of the print is carried on all around the T-shirt, just using the ends of the garment as natural finishing points.
Another type of design that works particularly well with sublimation printing, is photography prints. The method allows you to fill the whole surface with the photograph, instead of just placing it on the front of the garment in a rectangular fashion.
The tank top above uses the image of the flower, and a more muted background (because if you can fill the whole tank top, why not do so?)
Sublimation also works well when your garment requires a number of different logos or designs. With traditional printing, you may be charged for each separate logo application – whereas, with sublimation, a large number can all be incorporated and printed in one go.

Screen printing is the best option for designs that require a high level of vibrancy, specialty products, or for quantities greater than 6 pieces. While BuynPrint has no minimums for screen printing, price is usually a prohibitive factor under 6 pieces.
