1. Pigments
Pigments form the core of DTF inks, providing the color and opacity needed for high-quality prints. They are finely ground particles that are suspended in the ink formulation to achieve the desired color effect. Pigments are chosen based on their lightfastness, color density, and compatibility with the printing process.
- Types of Pigments: DTF inks typically use high-quality pigments, including organic and inorganic pigments. Organic pigments offer vibrant, rich colors, while inorganic pigments provide excellent lightfastness and durability.
- Function: Pigments are responsible for the color and opacity of the print, ensuring that the design stands out on the target material.
2. Binders
Binders are essential components of DTF inks, as they facilitate the adhesion of the ink to the PET film and the subsequent transfer to the fabric. Binders create a strong bond between the ink and the substrate, ensuring that the print remains durable and resistant to peeling or cracking.
- Types of Binders: DTF inks use specialized acrylic or polyester binders that are compatible with the powder adhesive used in the printing process.
- Function: Binders play a crucial role in the transfer process by ensuring that the ink adheres to the PET film and transfers effectively to the fabric without losing color or vibrancy.
3. Solvents
Solvents are used in DTF ink formulations to control the viscosity and flow properties of the ink, allowing it to be applied smoothly through the printhead. Solvents also help to suspend the pigments and binders evenly within the ink, ensuring consistent color distribution.
- Types of Solvents: In DTF inks, water-based solvents are commonly used due to their eco-friendly nature and compatibility with the printing process. Some formulations may also include glycol ethers or other solvents to enhance flow properties.
- Function: Solvents ensure that the ink flows smoothly through the printhead, reducing clogging and ensuring consistent print quality.
4. Additives
Additives are incorporated into DTF ink formulations to enhance various properties, such as adhesion, durability, and colorfastness. These additives can include UV inhibitors, dispersants, and other performance enhancers that improve the overall quality and longevity of the print.
- Types of Additives: Common additives in DTF inks include anti-caking agents, which prevent the ink from drying out in the printhead, and UV inhibitors, which protect the print from fading under sunlight.
- Function: Additives improve the overall performance and durability of the DTF ink, ensuring that the print remains vibrant and long-lasting.
Specialized Formulations in DTF Inks
DTF inks are available in various specialized formulations to cater to different printing needs. Here are some of the most common types of DTF inks:

CMYK (Cyan, Magenta, Yellow, and Key/Black) inks are the standard colors used for color printing in DTF applications. These inks are formulated to deliver vibrant, accurate colors and are essential for creating multi-colored designs.
- Function: CMYK inks allow for a wide range of color combinations, making them ideal for complex designs with gradients, shading, and intricate details.
2. White Inks
White ink is a critical component in DTF printing, especially when printing on dark or colored fabrics. It serves as an underbase layer, providing a solid foundation for the CMYK ink layers to adhere to and ensuring high opacity and vibrancy.
- Function: White ink is essential for achieving high-quality prints on dark materials, as it prevents the colors from being absorbed by the fabric and ensures that the design stands out.
3. Clear Coat Inks
Clear coat inks are used to add an additional layer of protection to the print, enhancing its durability and resistance to wear and tear. This layer can also provide a glossy or matte finish, depending on the desired effect.
- Function: Clear coat inks protect the print from fading, cracking, and abrasion, ensuring that the design remains vibrant and long-lasting.
