1. What is DTF Printing?
DTF (Direct-to-Film) printing is a popular digital printing method for garment labels and logos. It needs to print designs with CMYK and white ink onto a specialized DTF PET film, then spray the powder on the white ink, and finally transfer the designs to fabrics using a heat press machine. Unlike traditional screen printing or DTG (Direct-to-Garment), DTF allows:
- Less Fabric Limitations: DTF can be used on a wider range of fabrics, including cotton, polyester, nylon, and blends, unlike DTG, which works best on high-cotton content fabrics.
- Vibrant Colors: DTF prints offer vibrant colors and excellent durability, withstanding multiple washes without significant fading or cracking
- No Pre-Treatment Required: Unlike DTG, DTF does not need pre-treatment of the fabric, which saves time and effort.
- Cost-Effective for Small Runs: DTF is more economical for smaller production runs compared to screen printing, which has higher setup costs due to stencils and screens.
- Fine Details and Complex Designs: It excels in handling intricate artwork, gradients, and photorealistic images without the limitations of screen printing.
2. What Materials need for DTF Transfer
2.1 Core Equipment
- DTF Digital Printer: The primary function of a DTF (Direct to Film) digital printer is to apply high-quality ink and print intricate patterns onto transfer films. This state-of-the-art printing technology is essential for custom textile printing, allowing businesses to create vibrant designs on various materials. Many DTF printers are equipped with a user-friendly app that enables users to easily adjust printing settings, such as color profiles, resolution, and design placement. This feature enhances the overall printing process, making it more efficient and accessible for both small businesses and individual creators. Here are some suggestions for choosing a good DTF textile printer.
| Brand | Epson, Roland, Brother, Mimaki, and some OEM brand, most are produced in China |
| Printing Width | 30cm, 33cm, 40cm, 42cm, 45cm, 60cm, 75cm, 50cm, 80cm, 120cm and so on |
| Printheads | Some suppliers prefer to sell printheads separately, so be sure to inquire whether the printer comes equipped with the printheads. Commonly used printhead models include the Epson I3200 and XP600. We recommend 4 printheads for one printer. |
- DTF Powder Shaker: DTF shaker powder, also known as DTF adhesive powder or DTF transfer powder, is an essential material used in the direct-to-film printing process. This powder is crucial for creating high-quality, durable prints on various textiles.
- Heat Press Machine: Heat press machine is a specialized device designed to apply heat and pressure to transfer designs onto fabrics or other materials.
2.2 Consumables
- DTF Film Rolls/Sheets:
- Single Matte vs. Double Matte: You can choose what you need.
- Hot Peel vs. Cold Peel: For those who need to complete printing jobs quickly, the instant tear method is an ideal choice. On the other hand, customers who require more vibrant colors can opt for the cold tear method.
- Sizes: Sheet size for home desk printers, rolls for bigger printers.
- DTF Inks: Pigment-based inks with 20–30% elongation for stretch fabrics. CMYK + white color.
- Hot Melt Powder: Hot melt powder is a thermoplastic adhesive that is initially applied in a solid form and then melted using heat. It is applied on the white ink and acts as an adhesive for DTF printing. White powder is for most fabrics, while black powder is for sublimation fabrics. We recommend high-temperature melting adhesive powder.
