When it comes to printing custom apparel, there are two main methods: direct-to-garment (DTG) printing and direct-to-film (DTF) printing. Both methods have their own advantages and disadvantages, so it’s important to choose the right one for your business. In this article, we’ll take a closer look at DTF vs DTG printing and help you decide which method is best for you. We’ll discuss the pros and cons of each method, as well as the cost, quality, and flexibility of each. Also, we will provide some tips for choosing the right printing method for your business.
What is DTF Printing?
DTF stands for direct-to-film printing. It is a method of printing custom designs on garments using a special transfer film. The transfer film is first printed with the design, and then it is applied to the garment with heat. The heat melts the adhesive on the transfer film, which bonds the design to the garment.
DTF printing is a relatively new printing method, but it has quickly become popular due to its versatility and affordability. DTF printing can be used to print on a wide variety of garments, including cotton, polyester, and blends. It is also a good choice for printing on dark garments, as it does not require a white undercoat.
How does DTF printing work?
- Print on Film
Instead of using regular paper, it is recommended to use PET film for this printing process. Here’s how it works: Start by printing the complete image on the PET film, with white as the base layer. Next, select the desired colors and print the image on top of the white layer. Remember, it’s important to invert the image on the film for the best results.
- Spread the Powder
This step is to pour the hot melt powder onto the film. When printing wet images, you should ensure all the power that is distributed into the surface evenly. The ordinary way to spread the powder is to pour the powder at the center of the film from top to bottom such that it forms an approximately 1 inch pile. Pick up the film together with the powder and slightly bend it inwards such that it forms a slight U with the concave surface towards yourself. Finally, you shake the film slightly to make the powder spotted on the film evenly.
- Melt the Powder
In this step, the powder is melted. There are two ways to do this: using a curing oven or a heat press.
Using a curing oven: Place the film with the powder on it in the curing oven. Set the temperature to 160-170 degrees Celsius and let the powder melt for 2-5 minutes.
Using a heat press: Place the film with the powder on it in the heat press. Make sure there is a 4-7mm gap between the film and the heat press plate. Use a metal wire to fasten the press top so that the film does not move. Melt the powder for 2-5 minutes at 160-170 degrees Celsius.
The melting time and temperature may vary depending on the type of powder you are using. Follow the manufacturer’s instructions for the best results.
- Pre-press the Fabric
Pre-press means that pre-press the fabric before transferring the image. The purpose of pressing the texture for 2 to 5 seconds in the heat press is to dehumidify the fabric.
- Heat Transfer
The core step of DTF printing is to cure the film and fabric together. This is done by placing the PET film with the image and the melted powder on the fabric and applying heat. The heat melts the powder and bonds it to the fabric, creating a durable and long-lasting print.
The curing process is typically done at a temperature of 160-170 degrees Celsius for 15-20 seconds. The exact time and temperature may vary depending on the type of powder and fabric you are using.
- Cold Peel
Once the print is cured, it is important to allow it to cool down to room temperature before peeling off the film. The hot melt powder acts as a binder, which helps to bond the ink to the fabric fibers. If the film is peeled off too soon, the ink may not be fully bonded to the fabric and the print may peel off or crack.
To peel off the film, gently lift one corner of the film and peel it away from the fabric. The film should come away easily. If the film does not come away easily, you can use a heat gun to warm it up slightly.
Once the film is peeled off, you should be left with a beautiful, durable print that will last for years to come.
- Post-pressing
An alternative to peeling off the film is to heat press the fabric with the transferred design for 10-15 seconds. This will help to set the print and make it more durable.
DTF printing is a great choice for textile printing because it is versatile, durable, and cost-effective. DTF printing can be used to print on any type of fabric, including dark fabrics, and it can produce high-quality prints that are resistant to washing and rubbing. DTF printing is also relatively affordable, making it a good option for businesses with a limited budget.
What is DTG Printing?
DTG stands for direct-to-garment printing. It is a method of printing custom designs on garments using a digital inkjet printer. The inkjet printer sprays the design directly onto the garment, using special inks that are designed for use on fabric.
DTG printing has been around for longer than DTF printing, and it is still the most popular method for printing custom designs on garments. DTG printing can produce high-quality prints with vibrant colors. However, DTG printing is not as versatile as DTF printing, as it can only be used to print on garments that are made of cotton or a cotton blend.
How does DTG printing work?
DTG printing works by using a special inkjet printer that sprays water-based inks directly onto the garment. The inks are designed to be absorbed by the fabric, resulting in a durable and long-lasting print.
The steps involved in DTG printing are as follows:
- Preparation. The garment is first pre-treated with a water-based primer. This helps the ink to adhere to the fabric and prevents it from fading or cracking.
- Printing. The image or design is then printed onto the garment using the inkjet printer. The printer sprays the ink onto the garment in a series of dots, creating a high-resolution image.
- Curing. Once the ink has been printed, it is cured using heat. This process helps the ink to dry and bond to the fabric.
What is the difference between DTF and DTG printing?
Although both printing methods may appear similar at first glance, they possess significant differences. While both methods can deliver impressive results, there is more to them than meets the eye.
| Feature | DTF | DTG |
|---|---|---|

Dtf vs Dtg Print quality and durability
DTF printing offers excellent print quality. Although the print initially feels somewhat plastic and stiff, it becomes more comfortable and flexible after a few washes. DTF prints are smooth, elastic, and long-lasting. They resist cracking, can endure heavy use, and withstand cold to lukewarm washes without color fading. However, if washed in very hot water, small cracks may develop in the design.
This printing method is perfect for photos, colorful designs, graphics, and fine art. The ink sits on top of the fabric instead of soaking in, resulting in amazing, thin prints that don’t feel bulky.
Similarly, DTG printing delivers fantastic print quality. While a fresh print may feel slightly rough, it becomes smoother after a few washes. The print may have a slightly rubbery texture, but it doesn’t create an unpleasant tactile experience and is often barely noticeable.
DTG is ideal for printing colorful designs, graphics, text, and more. However, certain factors can impact the print outcome. Since the fabric absorbs the ink, the print’s vibrancy may be slightly reduced, especially on black or colorful garments.
By following the care instructions provided for the printed garment, you can expect long-lasting prints that resist cracking, peeling, and fading. The durability of these prints may pleasantly surprise you.
Print complexity
DTF printing excels in handling complex designs. It can accommodate photos, intricate full-color designs, fine art, small text, graphics, and more. The resulting prints are sharp, clear, and remarkably realistic, closely resembling the original design. Additionally, DTF printing allows for the reproduction of gradients. It is important to note, however, that the white ink used as the base in DTF printing can impact the appearance of gradients and design transparency.
Similarly, DTG printing supports a wide range of colorful designs, graphics, photos, fine art, small text, and more. The prints produced are vibrant, clear, and highly detailed. However, it’s worth considering that the ink is absorbed by the fabric, which can slightly affect the clarity of the design. Printing gradients with DTG can be challenging, requiring careful adjustment of the design. Further information about transparency in DTG printing can be found here.
Color vibrancy
DTF printing relies on the CMYK color model, which includes cyan, magenta, yellow, and black inks, along with white ink as the base. This combination ensures that every design appears vibrant and vivid, regardless of the fabric color or type.
Similarly, DTG printing also utilizes the CMYK color model for printing designs. However, the white base color is only used when printing on black or colorful garments, not on white fabrics. As the ink is sprayed directly onto the fabric in DTG printing, it gets absorbed, resulting in prints that may not be as bright or vibrant as those achieved through DTF printing. Nonetheless, DTG printing still produces impressive prints.
Fabric suitability
One of the benefits of direct-to-film (DTF) printing is its versatility in printing on different fabric types. This adaptable printing method can be used on polyester, cotton, fleece, nylon, and various fabric blends. The type of material does not impact the print, providing you with a wider range of product options to design for your store.
In contrast, DTG printing is most suitable for natural fabrics such as cotton, bamboo, linen, and similar fabric blends. This is because the ink adheres better to the natural fibers of these fabrics compared to synthetic fabrics.
Quantity
If you’re seeking a printing method that is well-suited for print-on-demand production, DTF printing is an excellent choice. Whether you want to print a single shirt or fulfill bulk orders of t-shirts, DTF printing aligns perfectly with the on-demand production model.
Similarly, DTG technology is also ideal for both small and large orders. It is widely favored among dropshipping companies because it offers ease of use and the ability to fulfill orders in any quantity needed.
Eco-friendliness
If you’re in search of a sustainable fulfillment method, DTF printing is a viable choice. This technique allows for on-demand printing, eliminating the concern of unsold stock and reducing the risk of overproduction. Additionally, the water-based and non-toxic inks used in direct-to-film printing are environmentally friendly. The transfer film utilized in the process is typically recyclable, further minimizing waste generation.
Similarly, DTG printing offers an eco-friendly fulfillment option. Like DTF printing, DTG enables printing one-offs, ensuring that you produce only what is ordered. For instance, Printful partners with Kornit, whose DTG machines are designed to generate minimal wastewater and consume less energy, effectively reducing the carbon footprint.
Furthermore, Kornit digital printers utilize water-based vegan inks that are formulated, tested, and produced in their own ink factories. These inks are non-hazardous, toxin-free, biodegradable, and contain no animal by-products.
Best Types of Garments for DTF and DTG Printing
After thoroughly examining each printing method, it is evident that both deliver exceptional results and are well-suited for businesses engaged in print-on-demand production. However, it is important to note that each technique yields distinct outcomes that can either enhance or compromise your design. Let’s summarize each approach for a better understanding.
DTF printing is best for garments that are made of cotton or a cotton blend. DTF printing can also be used to print on garments that are made of polyester or a polyester blend, but the results may not be as good.
DTG printing is best for garments that are made of cotton or a cotton blend. DTG printing cannot be used to print on garments that are made of polyester or a polyester blend, as the ink will not adhere to the fabric.
