Getting started with Direct-to-Film (DTF) printing can feel overwhelming, especially if you’re unfamiliar with the terminology. From understanding the materials involved to mastering the process, learning the basics is the first step to confidently navigating this innovative printing method. That’s why we’ve created this beginner-friendly glossary—your go-to guide for breaking down common DTF terms in simple, practical language.
Whether you’re a hobbyist, a small business owner, or just curious about how DTF printing works, this glossary will help you make sense of it all.
PET Film
PET stands for Polyethylene Terephthalate, a type of high-quality film used as the foundation for DTF printing. The design is initially printed onto this thin, durable sheet of film.
- Why it matters: PET film serves as the carrier for your designs. Its smooth surface ensures sharp, detailed prints that transfer beautifully to various materials. Look for films labeled “double-matte” for the best printing and transfer results.
Adhesive Powder
Adhesive powder, also known as hot melt powder, is applied to the printed design on the PET film. This powder binds the ink to the surface during the transfer process.
- Why it matters: The adhesive is responsible for the strong bond between your design and the material it’s transferred onto. It ensures durability and prevents peeling, even after repeated use or washes.
Curing
Curing refers to the process of heating the adhesive powder to set it in place on the printed design. This step is usually done in a curing oven or with a heat press.
- Why it matters: Proper curing ensures the adhesive activates correctly, setting the stage for a flawless transfer to your chosen surface.
Heat Press
A heat press is a machine that uses heat and pressure to transfer designs from the PET film onto the target material, such as a T-shirt or tote bag.
- Why it matters: The heat press is essential for achieving vibrant and durable results. It helps the adhesive and ink bond effectively with the surface. Temperature and pressure settings need to be tailored for different materials.
White Ink Layer
The white ink layer acts as a base underneath other colors to make the design pop, especially on dark or colored surfaces.
- Why it matters: Without the white ink layer, designs can appear dull or muted when applied to non-white items. It ensures the final product looks vibrant and professional.
Hot Peel vs. Cold Peel
These terms refer to when you can remove the PET film from the material after a design has been heat-pressed.
- Hot Peel: The film is removed while still warm, which can speed up the production process.
- Cold Peel: The film is removed once it has cooled completely, offering sharper and more defined results.
- Why it matters: Knowing the peel type ensures you handle the transfer at the right time, enhancing the quality of the finished product.
Gang Sheet
A gang sheet is a larger sheet of PET film that contains multiple designs printed together.
- Why it matters: Gang sheets allow you to optimize space and save on costs by printing several designs at once, making them ideal for large orders or diverse projects.
Rip Software
Rip software (Raster Image Processor) is used to prepare digital designs for DTF printing. It manages color calibration, ink placement, and print efficiency.
- Why it matters: This software ensures your designs are printed with precision and optimal ink usage, dramatically improving the end result.
DTF Ink
DTF ink is specially formulated to adhere to PET film and work seamlessly with the adhesive powder and transfer process. It typically includes CMYK (cyan, magenta, yellow, black) colors, as well as white ink.
- Why it matters: Only DTF-specific inks can produce the vibrant, durable designs that this method is known for.
Heat Transfer
The heat transfer is the actual process of pressing the printed and cured design onto the material using heat and pressure.
- Why it matters: This step brings the entire process together, turning your design into a permanent feature on the chosen surface.
Pre-Treatment
Some materials require pre-treatment to prepare them for DTF transfers. This can involve cleaning the surface or applying a special coating.
- Why it matters: Proper pre-treatment ensures the adhesive and ink bond correctly, extending the life of your design.
Washability
Washability refers to how well a DTF transfer holds up after being washed, especially on fabrics.
- Why it matters: High-quality DTF prints should withstand multiple wash cycles without fading or peeling. Properly cured and transferred designs ensure excellent washability.
Nonporous Materials
Nonporous materials include surfaces like glass, metal, or plastic that don’t absorb liquids.
- Why it matters: Unlike some printing methods, DTF works well on nonporous materials, making it a versatile choice for a wide range of projects.
Film Side vs. Print Side
The PET film has two sides:
- Film Side: The smooth side where the design is printed.
- Print Side: The slightly textured side where the adhesive powder is applied.
- Why it matters: Understanding these sides ensures you load and handle the film correctly during the printing process.
Color Boost
A technique or product enhancement that amplifies color vibrancy in the final design.
- Why it matters: If achieving bold, eye-catching designs is your goal, look for DTF solutions that offer features like Color Boost technology.
Transfer Time
The amount of time the heat press must remain on the design and material to complete the transfer.
- Why it matters: Incorrect transfer times can lead to incomplete bonding or uneven results, so timing is crucial.
Customizable Designs
Customizable designs mean that you can create one-of-a-kind transfers tailored to specific needs, such as logos, illustrations, or text.
- Why it matters: The flexibility of DTF printing allows you to explore endless creative possibilities, ideal for both personal and professional applications.
