DTF Ink Process
DTF Ink Process
The DTF (Direct to Film) printing technology can produce vivid, wash-durable patterns on a wide range of fabrics. To achieve the optimal printing effect, several key steps must be followed. Each step requires the use of dedicated materials and equipment to ensure the aesthetic appeal and durability of the printed patterns.
Step 1: Print the design onto PET transfer film
First, print the customized design onto a special PET transfer film. This thin, flexible and transparent film features a coated surface that enhances ink adhesion and enables a strong bond with fabrics during subsequent heating. Printing must be done with a printer compatible with DTF inks; the printer will print the design in layers, typically starting with the color sections and then applying a layer of white ink to boost the pattern’s vibrancy.
To ensure the best printing quality, note the following guidelines:
Use high-resolution images (a minimum of 300 pixels per inch).
Ensure the transfer film is flat and accurately aligned with the printer’s paper feed.
Allow the ink to air-dry slightly before proceeding to the next step.
Clean the print head regularly to prevent ink buildup.
Store PET transfer film in a dark, moisture-proof environment.
Tip: Always conduct a test print before mass production to check the color reproduction and sharpness of the pattern.
Some issues may arise when printing on PET transfer film: smudging can occur if the ink is not fully dry, and a dirty print head may cause uneven color distribution. It is essential to follow the printer manufacturer’s parameter settings, and the printed patterns should be cured for at least 24 hours to achieve the optimal effect.
Step 2: Apply Hot Melt Powder
After the design has been printed, apply hot melt powder evenly to the wet ink areas on the PET transfer film. The hot melt powder enables strong adhesion between the printed pattern and the fabric during the heat transfer process. A dedicated hot melt powder applicator or a fine mesh sieve can be used to ensure uniform powder distribution across the entire printed surface.
To achieve optimal results when applying powder with a fine mesh sieve, follow these steps:
Position the sieve approximately 10-15 cm above the transfer film.
Gently shake the sieve to allow the powder to evenly covers the entire printed area.
Tilt the transfer film to shake off any excess powder.
Lightly tap the back of the transfer film to remove loose powder residue.
Place the transfer film into an oven or heat press and cure it at the appropriate temperature for 30-60 seconds, allowing the powder to melt and form a smooth adhesive layer.
The standard curing temperature for regular hot melt powder ranges from 160-180°C, while low-temperature hot melt powder should be cured at 130-150°C. Always verify the type of hot melt powder before curing.
Insufficient application of hot melt powder may result in weak adhesion between the print and the fabric, whereas excessive powder application can cause thick, uneven prints. The powder application tray and related tools should be cleaned daily to ensure a smooth and stable production process.
Step 3: Heat Transfer onto the Fabric
Next, transfer the pattern onto the fabric. Place the PET transfer film pattern side facing down and position it onto the fabric surface. Use a heat press to apply the appropriate temperature and pressure. This process allows the ink to bond firmly with the adhesive layer and the fabric, ensuring the pattern becomes an integral part of the fabric.
Below is a table of commonly used heat press parameters for different fabric types:
| Fabric Type | Temperature (°F) | Time (seconds) | Pressure | Peel Type |
| Cotton | 315 | 15 | Medium to firm | Cold peel |
| Polyester & Synthetic Blends | 290 - 300 | 12 - 15 | Light to medium | Hot peel |
| Nylon & Stretch Fabrics | 275 - 285 | 12 - 15 | Light | Cold peel |
| Leather & Hard Surfaces | 280 - 300 | 20 | Medium | Cold peel |
Always confirm the fabric type before heat pressing: cotton and cotton-polyester blended fabrics offer the best compatibility, with excellent ink absorption and high heat resistance. Polyester fabrics can also be printed, but the temperature should be reduced to prevent fabric deformation or melting. Avoid printing on silk and wool whenever possible, as these fabrics are sensitive to heat, prone to scorching, and more likely to cause printing defects.
Note:Allow the fabric to cool naturally before peeling the film. This helps the design bond more securely to the fabric and prevents edge lifting.
By strictly following the above steps, you can achieve vivid, durable, and wash-resistant prints that remain intact even after multiple washes. DTF ink is compatible with a wide range of materials, making it an ideal choice for custom apparel and promotional products.
Comparison of DTF Ink Other Inks
Comparison with Sublimation Ink
You may wonder about the differences between DTF (Direct to Film) ink and sublimation ink. Sublimation ink is best suited for polyester fabrics. During printing, the dye penetrates into the fabric fibers, producing vivid colors and sharp details. Because the dye bonds directly with the fibers, the prints offer good durability; however, the colors may gradually fade after repeated washing.
DTF ink, by contrast, uses a pigment-based formulation. The printed design adheres to the fabric surface, typically with a white ink base layer applied to enhance brightness and visual impact. DTF ink is compatible with a much wider range of materials, including cotton, polyester, and blended fabrics, whereas sublimation ink is primarily limited to polyester substrates.
Features | DTF Printing | Sublimation Printing |
Fabric Compatibility | Cotton, polyester blends, spandex, nylon, and more | Best suited for polyester or polyester blend fabrics |
Color Saturation | Rich, vibrant colors with an optional white ink base layer | Bright and sharp, but prone to fading over time |
Wash Fastness | Good; minor wear may occur on stretch fabrics | Excellent, as dyes permanently bond with fabric fibers |
Note: DTF ink offers a wider range of fabric options and more striking print colors, while sublimation ink delivers superior print durability on polyester fabrics.
Comparison with Conventional Inks
Conventional pigment inks are primarily designed for paper or specially treated surfaces and have limited adhesion to fabrics without pre-treatment. In contrast, DTF white ink is directly compatible with a wide range of fabrics, including cotton and polyester, delivering prints with higher color saturation, stronger adhesion, superior durability, and a more professional finish.
