Understanding how sublimation printing works

“Sub-li-what-now?!”

If you've ever wondered what this strange-looking word actually means — then wonder no more.

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 used mostly for print on demand apparel. 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.

What is sublimation?

Let's start with the broad strokes. What exactly is sublimation?

In simple terms, it's a method of printing that transfers a design into a material or fabric using ink and heat.

In the world of apparel, it's a game changer in that it allows whole garment prints — designs that go seam-to-seam.

The sublimation printing process

So how does sublimation work? Well, sublimation printing uses heat to essentially bring ink and fabric together as one.

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 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.  Sublimation printing is also known as  ‘all over printing' as it allows you to choose a design that can literally go from seam to seam.
