DTF Ink Application

01 Background

DTF Ink Application is a cutting-edge printing technology that directly transfers designs onto garments by first printing them onto a polyester film, which is then applied to fabrics using a heat press machine. This method offers significant advantages over traditional screen printing, including simplicity, flexibility, and the ability to produce vibrant, multi-colored designs. As a result, it has quickly gained popularity in the T-shirt customization industry, offering an excellent solution for both small-batch custom orders and large-scale mass production.

One of the key features of DTF printing is its hot-melt technology, which bonds the printed design directly to the fabric without the need for pre-treatment. This not only simplifies the process but also eliminates additional steps, saving both time and labor. DTF printing is more cost-effective than DTG printing, primarily because the ink is less expensive, making it a more affordable option for businesses and customers alike. The printing process is also faster than DTG, allowing for quicker turnaround times on orders, while being compatible with a wide range of fabrics. These include cotton, polyester, nylon, canvas, denim, and various blended materials. In contrast, DTG printing is limited to printing on 100% cotton fabrics, making DTF printing a more versatile solution.
