DTF Printing in Sri Lanka: Process, Materials & Benefits
If you follow the custom clothing scene in Sri Lanka, you've probably heard people talking about DTF printing. Small Instagram boutiques in Colombo use it. Uniform suppliers in Maharagama use it. And more print shops are adding DTF machines every month.
For years, local brands had two main choices: screen printing or sublimation. Both work, but both come with limits on fabric type, colours and minimum order size. DTF gets around most of those limits.
In this guide, we'll walk through what DTF printing is, the materials you need, how the process works, and whether it's the right fit for your next project.
What Is DTF (Direct-to-Film) Printing?
DTF stands for Direct-to-Film. Your design is printed onto a clear PET film, covered with an adhesive powder, cured, and then heat pressed onto the fabric.
There are no screens to make and no weeding (cutting away the empty parts like you do with vinyl). That means you can print full-colour artwork, fine details and even photos straight onto a garment.
Materials Used in DTF Printing
A good DTF print comes down to four things working together.
1. PET Transfer Film
Everything starts with PET (polyethylene terephthalate) film. It has a special coating that holds the ink in place. You'll find it in two types: hot-peel (peel right after pressing) and cold-peel (wait until it cools).
2. Water-Based DTF Inks
DTF printers use water-based pigment inks in CMYK plus white. The white ink is the key. It goes down as a solid base behind the colours, so your design stays bright even on black t-shirts.
3. Hot-Melt Adhesive Powder
While the ink is still wet, a TPU (thermoplastic polyurethane) powder is spread over it. The powder only sticks to the inked areas. Once melted, it works like a strong, flexible glue that bonds the print to the fabric.
4. The Fabric
This is where DTF really shines. Sublimation needs polyester, but DTF works well on:
100% cotton
Polyester and poly-cotton blends
Silk and rayon
Denim and canvas

How the DTF Printing Process Works
The process is quick, which is why it suits both one-off prints and bigger runs.
Print the film: The design is mirrored and printed onto PET film. Colours go down first, then a white layer on top.
Apply the powder: Hot-melt powder is spread evenly over the wet ink and the extra is shaken off.
Cure: The film goes through a curing oven (or is held under a heat press without touching) until the powder melts into a smooth layer.
Heat press: The film is placed on the garment and pressed at around 150°C to 165°C for about 15 seconds.
Peel: Peel the film away (hot or cold, depending on the film). You're left with a bright, stretchy print.
DTF vs Screen Printing vs Sublimation
So why are so many Sri Lankan brands switching? Here's a quick comparison.
DTF vs screen printing: Screen printing is great for large bulk orders, but every colour needs its own screen. That makes small runs expensive. With DTF, printing a single multi-colour t-shirt is affordable.
DTF vs sublimation: Sublimation dyes the fibres, so it only works on light-coloured polyester. DTF sits on top of the fabric, so it works on dark colours and pure cotton too.
Digital methods like DTF also use far less water than traditional printing and dyeing. You can read more about the different methods in this overview of textile printing.
Why Sri Lankan Apparel Brands Are Switching to DTF
Local buyers want more personalised clothing, and brands want to launch without huge upfront costs. DTF helps with both.
Low start-up costs: Many print shops in Colombo and Pettah now sell DTF gang sheets. You send your designs, they print them onto one large film, and you press them onto your garments at home or in your workshop.
Durability: A well-made DTF print resists cracking and fading and holds up through many washes, even in our hot, humid climate.
Less waste: Water-based inks and a mostly dry process make DTF a better choice for brands trying to be more sustainable.
DTF Printing FAQs
How long does a DTF print last?
With good film, ink and correct pressing, a DTF print can last for dozens of washes. Wash inside out in cool water and avoid ironing directly on the print.
Can I do DTF printing without a printer?
Yes. Buy ready-made DTF transfers or gang sheets from a local print shop and apply them with a heat press. A household iron can work for testing, but a heat press gives much more reliable results.
Is DTF better than sublimation?
It depends on your fabric. For cotton or dark garments, DTF is the better choice. For light polyester sportswear where you want no feel on the fabric, sublimation still works well.
Is DTF Right for Your Brand?
If you're a designer, boutique owner or small clothing brand in Sri Lanka and you want bright colours, low minimum orders and the freedom to print on almost any fabric, DTF is well worth trying. It gives you commercial-quality prints without the big setup costs.
