How To Print Flags (fabric) Using Dye Sublimation
Turning plain white polyester into high impact graphics.
Ever wondered how we turn plain white polyester into high-impact, professional fabric graphics? Whether it’s flags, Heras fence panel covers, custom tablecloths, backdrops or SEG graphics, it all starts with dye sublimation – and we use the direct dispersal method.
So, how does it work?
Unlike transfer printing (which uses paper), we print directly onto the fabric using water-based dye-dispersal inks. The colour goes on looking pale and chalky – not very impressive at first glance.
But then comes the magic.
We run the printed fabric through a heat press, or in small-scale demos, we use a handheld mini press to apply heat. This is called fixation – the point where the ink turns from liquid into gas and permanently bonds with the polyester fibres. The transformation is magic.
In our video demo, a washed-out brownish orange suddenly becomes a vibrant, zingy orange the moment heat is applied. That’s dye sublimation in action – the heat brings the colour to life.

Why direct dispersal?
No paper waste – it’s printed straight to fabric, which is cleaner and more efficient.
Vivid colour results – bright, bold, durable.
Long-lasting – colours won’t crack or peel; they’re locked into the fabric.
Perfect for tension frames, flags & event graphics – lightweight, crease-resistant, and easy to install.
We use this method daily to produce a wide range of soft signage products, including:
Feather flags SEG fabric graphics
Printed backdrops
Custom tablecloths
Heras fence panel banners
