The KTM-1904, a 4-head high-speed sublimation printer, utilizes Direct-to-Film (DTF) technology to revolutionize textile printing. This innovative process bypasses traditional limitations, offering a versatile and efficient solution for transferring vibrant designs onto various fabrics. Let's delve into the mechanics and workflow of the KTM-1904, exploring the key components and steps involved in DTF printing.
1. Printhead and Ink System
At the heart of the KTM-1904 lie four high-precision 13200-A1 printheads, renowned for their exceptional speed and accuracy. These printheads meticulously deposit water-based pigment inks onto a special PET film. The printer boasts an exclusive all-aluminum ink stack, ensuring durability and reliability throughout the printing process.
2. Auto Constant Temperature Drying System
Following ink deposition, the printed film passes through an automated drying system. This crucial step ensures uniform heat distribution, allowing the ink to be thoroughly absorbed by the PET film. The controlled drying process is vital for achieving optimal color vibrancy and image sharpness.
3. Powder Adhesive Application
The dried film then advances to the powder adhesive application stage. Here, a thin layer of thermoplastic polyurethane (TPU) powder is evenly distributed onto the printed surface. The powder adheres specifically to the wet ink, creating a raised texture that will later facilitate bonding with the fabric.
4. Curing and Melting
The film, now coated with TPU powder, undergoes a curing process. This involves exposing the film to controlled heat, melting the powder and solidifying its bond with the printed ink. The result is a durable and flexible film, ready for transfer onto the desired textile.
5. Heat Press Transfer
The final stage involves transferring the design from the film to the fabric using a heat press. The fabric is placed on the heat press platen, followed by the printed film with the TPU layer facing down. Applying heat and pressure activates the adhesive properties of the TPU, permanently bonding the design to the fabric.
6. Finishing
Once the transfer is complete, the PET film is peeled away, leaving behind the vibrant and detailed design on the fabric. The printed textile is now ready for use or further processing, depending on the desired application.
