Direct-to-Film (DTF) printing has emerged as a highly flexible, efficient method for decorating garments, and it is especially powerful for transferring crisp, durable designs onto hats. Below, we outline how a DTF printer works, the step-by-step process of transferring a design to a cap, and the types of materials on which DTF printing can be used.
A DTF printer, short for “Direct-to-Film,” is a digital printing device that first prints a design onto a special PET (polyethylene terephthalate) film, instead of directly onto fabric. According to Disen Machinery, the printer applies color inks (CMYK) and a layer of white ink to ensure that the design pops on both light and dark backgrounds.
After printing, a hot-melt adhesive powder is applied, then the film is heat pressed onto the target material, transferring the design.
Compared with other printing techniques like DTG (direct-to-garment), DTF avoids pre-treatment steps and allows more versatility in substrate choices.
Disen offers DTF printers in various sizes—for example, their DS-MC301 (30 cm A3) model integrates printing, powder shaking, and baking in one unit, making it easy and efficient to operate.
A larger model, like the DS-MC760DW, uses Epson I3200 print heads and supports wide PET film rolls.
Disen Machinery describes a clear, five-step workflow for converting a design into a durable, high-quality print on a hat. Here is how it works:
Everything starts on the computer. Designers use software such as Adobe Illustrator, Photoshop, or CorelDRAW to create or refine their artwork. Disen supports file preparation by helping users adjust resolution, colour profiles, and formats to make sure the print result is sharp and vibrant.
Once the artwork is ready, it’s sent to the DTF printer. The design is printed onto a PET transfer film, layer by layer: first the colour inks, then a white underlay. The white ink ensures that the design stands out, even on darker fabrics.The precision of the printer and the consistency of the ink delivery are essential for vivid, accurate reproductions.
Immediately after printing, the printed film is coated with a hot-melt adhesive powder. This powder sticks to the wet ink. Then, by gently heating (or shaking), the powder begins to melt and bind with the design, forming a cohesive layer. Disen provides high-quality powder along with its printers, so users don't need to worry about sourcing adhesives.
The prepared film (with melted powder) is then placed onto the hat. A heat press machine applies precise heat and pressure for a specific duration to transfer the design from the PET film onto the fabric.Disen highlights that its heat presses are uniform, reliable, and long-lasting, making them suitable both for beginners and experienced users.
For hats, Disen’s “Cap Solution” workflow describes how the printed film can be heat pressed onto different hat shapes and sizes.
After pressing, the PET film is peeled away, leaving the design firmly attached to the hat. The result is a high-definition, durable print. According to Disen, these transfers can resist multiple washes without cracking or fading, thanks to the strong bond created by the adhesive powder.
One of the major advantages of DTF printing is its material versatility. Disen Machinery highlights that their DTF technology supports a broad spectrum of fabrics, making it ideal for hats of various types. Specifically, DTF can be used on:
Cotton
Polyester
Linen
Nylon
Blends of synthetic and natural fibers
Because of this flexibility, DTF printing is well-suited for hats made out of common materials, whether they are cotton caps, polyester baseball hats, or mixed-fiber fashion headwear. Disen also notes that their method produces bright, long-lasting designs that adhere securely to textured or dark fabrics.
High Definition & Rich Colors: Because the design is first printed on film, you can achieve very fine detail, gradients, and vibrant colours.
Durability: Thanks to the hot-melt powder and proper heat transfer, the print bonds solidly to the fabric, offering strong wash resistance.
Material Compatibility: Unlike some printing techniques that struggle with synthetics or mixed fibres, DTF works on a wide variety of fabrics.
No Pretreatment: There is no need for pre-treatment of fabric, which simplifies the workflow compared to some other printing methods.
Scalability & Efficiency: With Disen’s printers (such as their wide-format models), you can produce many transfers quickly and consistently.
DTF printing represents an elegant, flexible, and cost-effective solution for transferring high-quality designs onto hats. The process — from digital artwork to film printing, powder application, heat pressing, and peeling — ensures vibrant, durable results on a broad variety of fabrics. Disen Machinery’s DTF printers and associated consumables make this workflow accessible for businesses large and small. Whether you're making custom baseball caps, fashionable bucket hats, or any other headwear, DTF offers a powerful tool to bring your creative designs to life with excellent quality and longevity.
