What is DTF ink?
DTF ink is used in Direct-to-Film (DTF) printing, a digital printing method that transfers ink onto a film or transparent transfer sheet and subsequently onto a substrate like cloth or solid surfaces. You can use it with particular DTF printers and substrates and comes in solvent, water, and sublimation-based formulations.
What is DTF ink made of?
DTF ink contains pigments, resins, and other ingredients that attach to a variety of surfaces and create brilliant, long-lasting prints. Depending on the ink type and application, the precise composition of DTF ink might change, however the following are some of the standard ingredients:
- Pigments: Colored pigments are used in DTF ink to give the ink its colour and opacity. Carbon black, titanium dioxide, and other chemical and inorganic substances are used to make pigments.
- Resins: Resins are binders that keep the pigments in the DTF ink together and help it adhere to the substrate. Acrylic, urethane, and vinyl resins are often included in ink.
- Additives: Additives increase DTF ink flow, viscosity, and drying time. Additives include thickeners, surfactants, and drying agents.
- Solvents: Solvent-based DTF ink helps dissolve pigments and resins and flow. Ink type and application determine solvent type and volume.

Types of Ink Used in DTF Printing
Let’s see what kind of ink is used for DTF printing.
Pigment Ink
One of the ink kinds utilised in DTF printing is pigment ink. Pigment inks include microscopic, solid pigment particles in a liquid carrier. It forms a coating of colour on the substrate, unlike dye-based inks, which dissolve in liquid and soak into it.
Pigment ink is a great option for printing on materials that will be exposed to sunshine, heat, or moisture because of its strength and resistance to fading. You can use this ink type for printing high-quality photographs, graphics, and artwork since it reproduces colours vividly.
This ink generates bright, crisp, high-contrast prints. Since ink particles reside on top of the substrate, printing is more precise and controlled. Pigment ink prints on cloth, paper, and plastic without bleeding or smudging.
Pigment ink has limitations too in DTF printing. This ink is more costly and requires a stronger printer to print well. In certain situations, the ink particles sitting on top of the substrate might generate a small roughness on the substance.
Overall, pigment ink is a great option for printing sharp, long-lasting graphics, photos, and artwork. Textile, fine art, and picture printing use it because to its fade resistance and rich colour reproduction.
Sublimation Ink
The DTF printing process also uses sublimation ink. Sublimation ink, unlike pigment ink, is dye-based and bonds with polyester materials by sublimation.
Sublimation ink offers vivid, rich colours that resist fading and breaking, making it useful for printing on polyester. When exposed to high temperatures, the heat-sensitive dye molecules in sublimation ink will transform from a solid to a gaseous state. This bonds the dye to the polyester strands, creating a permanent, full-color print that won’t peel, fracture, or fade.
This ink type generates a soft, flexible print that doesn’t add weight or rigidity. This makes it the perfect option for printing on breathable, light textiles used in athletics, activewear, and performance clothing.
DTF printing using sublimation ink has significant drawbacks. Sublimation ink is only appropriate for polyester materials. For correct colour reproduction, the cloth must be white or light-colored because the dye molecules must connect with the polyester strands.
Overall, sublimation ink is a great option for producing vibrant, long-lasting prints on polyester materials. Sports gear, promotional goods, and customised gifts use it because to its brilliant colours and smooth, flexible feel.
Solvent Ink
In DTF printing, solvent ink is a kind of ink used to dissolve into a solvent carrier, which then evaporates when the ink dries. As a result, a coating of colour is left on the substrate’s surface, that translates into a robust and long-lasting print.
Solvent ink is great for printing vinyl banners, car wraps, and outdoor signs because of its durability, water-resistance, and scratch-resistance. Industrial printing on metal or plastic surfaces uses it too.
Its adaptability is one of its key benefits. You can apply it to a variety of surfaces, including metal, glass, ceramic, vinyl, PVC, and other plastics. Solvent ink furthermore creates a premium, glossy surface perfect for outdoor advertising and promotional products.
But, solvent ink in DTF printing has significant downsides. While printing, solvent ink may release harmful fumes, thus ventilation and safety gear are essential. Solvent ink may need specific handling and disposal to protect the environment.
Solvent ink is a great option for printing tough, long-lasting images on a variety of surfaces. Its flexibility and durability make it a popular option for outdoor advertising and industrial printing, but its toxicity and environmental effect may limit its use.
How Ink Affects DTF Printing Quality?
Ink plays a significant part in defining the quality of DTF prints. Ink affects DTF printing quality in several ways:
- Color Accuracy: Ink quality influences DTF printing colour accuracy. High-quality ink with consistent pigments may generate more accurate, bright colors in prints.
- Opacity: Ink opacity affects how much of the substrate colour is visible through the ink. When printing on dark surfaces, high-opacity ink prevents substrate colour from seeping through and distorting the picture.
- Durability: The durability of DTF transfers are mostly affected by the quality of the ink used. Inks that are resistant to fading, cracking, and peeling are vital for generating long-lasting prints that can survive wear and tear.
- Adhesion: The adherence of ink to the substrate is crucial to generating crisp, high-quality prints. Ink that does not adhere effectively to the substrate might result in smearing or partial prints.
- Curing: It’s all about drying and hardening the ink after printing. Ink that does not cure correctly might result in poor-quality prints that are prone to smearing or fading over time.
Factors to Consider When Choosing Ink for DTF Printing
To achieve the finest results possible when selecting ink for DTF printing, you need to take into account a number of things. These factors comprise of:
- Compatibility with substrate: The kind of ink you choose is significantly influenced by the substance you want to print on. Some inks are made for cloth, plastic, or metal, while others are more adaptable. The improper kind of ink might cause smudging, poor adhesion, and other problems that can ruin your print.
- Color vibrancy and accuracy: Ink quality affects print colour vibrancy and accuracy. Higher-quality inks produce brighter, more vivid colours that are less prone to fade over time. When printing designs with precise colour requirements, it’s critical to use an ink that provides accurate, consistent colours.
- Durability and resistance: Certain applications need ink that resists fading, breaking, and peeling. For instance, an ink that can survive exposure to the outdoors without losing its colour or clarity is necessary if you’re printing outdoor signs. If you’re printing on materials that you will wash or wear, you’ll need an ink that will withstand repeated usage.
- Environmental concerns: Solvent-based inks may damage the environment and need specific handling and disposal. Where feasible, use an ink that is waste-free and is beneficial to the environment. This protects the environment and saves money by decreasing disposal expenses and regulatory penalties.

Control of temperature and humidity: You should keep DTF ink in a cool, dry area with constant temperatures and levels of humidity. Severe temperature or humidity variations might affect ink performance and consistency.
Prevent exposure to light: DTF ink pigments may fade or break down when exposed to UV or direct sunshine. Avoid direct light and keep DTF ink in a dark or opaque container. Before using DTF ink, shake it vigorously to spread the pigments.
Maintain a clean workspace: Dust, grime, and other ink remnants may degrade the quality of DTF prints. To avoid contamination, it’s critical to handle and transfer ink using clean tools and equipment.
Unused ink disposal: Local laws require appropriate disposal of unwanted or expired ink. Never flush ink down the toilet or discard it in the garbage.
Examine expiry dates: DTF ink has a shelf life, thus it’s crucial to do so before using the ink. Using expired ink might reduce its durability and efficacy.
How long does DTF ink last?
DTF ink lifetime depends on formulation, storage, and use. DTF ink typically has a shelf life of 12 to 24 months when maintained properly, such as in a cool, dry location away from UV or direct sunlight.
Before using ink, verify its expiry date. The longevity of printer ink depends on variables including frequency of usage, printer maintenance, and printing circumstances.
DTF ink can create high-quality prints for many months to a year or longer with appropriate care and use. But, if the ink is not properly cared for or kept, it may dry up, clog the printhead nozzles of the printer, and have a shorter lifetime.
Is DTF ink the same as sublimation ink?
No, DTF ink and sublimation ink are not the same. While people use both kinds of ink in digital printing, their characteristics and intended uses vary.
DTF ink is printed onto a specific film and heat-pressed onto the final substrate for direct-to-film printing. The pigments, resins, and other additives that ink normally includes, cling to a variety of surfaces and create vivid, long-lasting prints.
Contrarily, dye-sublimation printing uses sublimation ink, which is printed on transfer paper before being heated up and transferred to a polyester or other synthetic material substrate. Sublimation ink comprises dyes that sublimate or evaporate under heat and pressure and link with polyester fibres to create a high-quality, permanent print.
Can I use sublimation ink for DTF printing?
Sublimation ink is not advised for DTF printing since the two kinds of ink have distinct qualities and are made for various printing techniques. DTF ink is intended for direct-to-film printing onto a release liner and transfer to the final substrate, whereas sublimation ink works with sublimation transfer paper and polyester or polymer-coated substrates.
Sublimation ink for DTF printing may not bind with the film or transfer to the final substrate, resulting in poor ink adherence, colour transfer, and image quality. Sublimation ink is less opaque than DTF ink, which may reduce coverage and colour vibrancy on dark surfaces.
Using premium DTF ink that is optimized especially for your printer and substrate will help you get the greatest results from DTF printing. This will help you get the best prints possible and ensure appropriate ink adherence, colour brightness, and durability.
Can you mix DTF ink?
