What is DTF and How Does it Work?
DTF, or Direct-to-Film transfer technology, is a relatively new printing method that has recently gained popularity. It refers to a printing process where artwork is transferred from a computer onto a transfer film sheet and then moved onto a garment or substrate using a heat press. The DTF transfer film sheet is a revolutionary print medium that uses an adhesive powder layer combined with other layers of ink to create an image that is then transferred onto the garment. The process simplifies print production for businesses and DIYers alike, as it requires no pretreatment, is easy to use, and offers a wide range of design possibilities.
Understanding DTF Transfer Film Sheets
DTF printing involves using DTF transfer film sheets- a type of vinyl sheet on which designs and logos are printed before being transferred onto garments. The transfer film sheets come in different sizes and thicknesses but are generally designed to withstand the high heat and pressure required during the transfer process. DTF transfer film sheets work by having an adhesive layer to the printed surface activated when heat is applied to the sheet, allowing the prints to be transferred onto the garment.
Direct-to-Film Transfer Process Explained
The DTF transfer process requires several steps before transferring onto fabrics. Firstly, a design is created and printed onto the DTF transfer film sheet. Once the transfer sheet is printed, a layer of adhesive powder is applied on top of the ink layer using a sifter. The sticky powder sticks to the ink and acts as a bonding agent. Next, the print is passed through a heating and curing machine. The heat from the engine melts the adhesive powder and binds it with the ink, providing a firm adhesion between the transfer film and the substrate. Finally, the transfer film sheet is applied to the garment using a heat press, whereby high heat and pressure are applied, causing the powders to release from the sheet and stick to the garment.
Benefits of DTF Transfer Film Sheets
DTF technology offers several benefits over other printing methods. Firstly, DTF printing requires no pretreatment, allowing for easy printing without additional preparation, saving time and money. Secondly, DTF printing provides a high-quality image transfer onto fabrics, as the adhesive powder used during the process leads to a strong bond between the print and the material, meaning that designs won’t crack, peel, or fade over time. Finally, DTF printing offers an extensive range of finished products, as the technology is ideal for printing onto textiles, wood, and even metal surfaces.
How to Print on DTF Film Sheets
Printing on a DTF transfer film sheet involves selecting the correct type of printer suitable for the process. DTG or digital direct-to-garment printers are a good choice, but special DTF-compatible ink must be used to print onto the transfer film sheet. Next, a standard printer must print the design in reverse onto the film sheet. Once printed, the adhesive powder layer is applied to the ink layer using a sifter and a curing machine. Adding extra adhesive powder will increase the depth of the ink, making the print more vibrant.
Choosing the Right Printer for DTF Printing
When choosing a printer suitable for DTF printing, one should consider several factors, including the quality of prints produced, the ink type used, the speed of printing, and the overall cost of ownership. Epson SureColor P400 and Canon Pro-100 are two of the most popular printers for DTF printing due to their affordability, exceptional print quality, and versatility. However, a DTF printing specialist can recommend the most suitable printer based on specific production requirements, budget, and personal preferences.
