Why DTG
What is DTG?
Create high-quality printed garments with minimal training or experience.
Direct to garment printing (or DTG) is simply an emerging garment decorating technology that became widely available in the commercial market in the mid-2000s. Unlike traditional labor-intensive processes such as screen printing and embroidery, DTG utilizes inkjet printing technology to send a full color, detailed design directly from a computer to a digital printer with a garment loaded into it.
Piezo print heads then jet opaque white ink and translucent CMYK ink onto the garment and recreate the digital artwork. These inks are water-based, eco-friendly inks that are specifically designed to adhere to fabric when heat cured.
DTG makes it simple to create high-quality printed garments and relieves you from needing highly skilled, extensively trained employees with years of printing experience.
Do more with DTG
Let technology take the place of costly labor and lengthy skills training. With DTG printing, a single person can take an order, print the items and prep everything for delivery before quickly moving on to the next job.
- Unlimited color options and design reproduction
- Efficient short runs and one-offs
- Quick and easy reprints
- Faster output and response to market trends
- Seamless printing over zippers and other difficult garments
- Reduced labor and training requirements
- Easier set up and smaller space requirements
DTG Process
-
Step 1: Pretreat and Cure the Garment
When printing with white ink, apply the proper amount of pretreat depending on the garment preferably with a Brother-recommended pre-treatment machine for optimal results. Then simply cure the pretreat solution with either a heat press or dryer to ensure a flat printing surface.
-
Step 2: Prepare the Digital Art
Load your artwork into our new GTX Graphics Lab software. GTX Graphics Lab allows you to position the image, add text, distress layers and make other adjustments to your image before sending the file to print using the GTXpro print driver. Optionally, you can also print directly from your own graphics software.

Step 3: Printing on the Garment
Dress the platen with your desired garment or substrate and press print.
-
Step 4: Cure the ink on the Garment
Place the printed garment on to the heat press once again or in a forced air dryer to cure the ink. This will ensure the ink is fully cured to the garment and will have the desired washability.

FAQ
-
How much space do I need?You can set up your GTXpro printing station in a spare room, garage or just about anywhere convenient. Dimensions are 55" (W) x 51" (D) x 21" (H) (1400mm x 1290mm x 535mm). You'll also need a heat press and automatic pretreater. The average user can run a full setup in a 12' x 12' room.
-
What type of environment should the GTXpro be in?The room should be clean and climate controlled. Temperature should stay between 50°F (10°C) and 95°F (35°C) with relative humidity between 20%-85%. When printing, it is recommended to be within 64°F (18°C) to 86°F (30°C) with humidity 35%-85%.
-
What items can I print on?Items with open, porous fibers like 100% cotton are ideal. Other untreated/unsealed items such as stone coasters, natural wood, and raw leather may also allow inks to bind. New substrates should be tested before going into production.
-
Can I print on more than the center of the shirt?GTXpro print heads have a large print head-to-substrate gap, making it easier to print over zippers, seams, pockets and more. This allows wrap-around prints on t-shirts, printing over pockets/zippers on hoodies, and even over eyelets on shoes, since the print head never touches the substrate.
-
Do I need to print every day?No. The GTXpro printer has built-in maintenance procedures and tools that allow the printer to sit idle for multiple days, including an advanced maintenance station with wetting/capping stations and a white ink circulation system.
-
How long does it take to cure the inks?The GTXpro uses Innobella Textile waterbased pigment inks which cure quickly: 35 seconds at 356°F with a heat press, or 2-3 minutes dwell time in a conveyor dryer/box at 320°F.
-
What software comes with the GTXpro printer?The GTXpro can work on PC or Mac. Users can print directly from their graphic design software using the GTX print driver. Brother also provides GTX Graphics Lab for layout and artistic effects. Supported OS: Windows 8.1/10 (64-bit), macOS 10.14 Mojave, macOS 10.15 Catalina.
-
What is a print head? Who manufactures it?A print head is the component that jets ink droplets onto the substrate to recreate artwork. The GTXpro uses two piezo print heads for CMYK and white inks. Only a few companies manufacture print heads worldwide, and Brother is one of them, manufacturing the GTXpro print head itself.
-
What maintenance is required for the GTXpro?GTXpro is an industrial DTG printer. Many maintenance procedures are performed automatically by built-in features daily, as long as the printer remains powered on.
-
What is Innobella Textile Chemistry?Innobella Textile inks provide a large color gamut for reproducing customer artwork. Brother also created a new pretreatment formula to work with these inks, making it easier to print on more garment colors. Innobella Textile inks are tested and certified eco-friendly.
-
How many prints per hour can the GTXpro do?The GTXpro is the fastest printer Brother DTG has ever manufactured. Print time varies depending on design size and whether white ink is used.
-
What is the cost of a print on GTXpro?Cost per print depends on design size, whether printing CMYK or CMYK+White, the colors in the design, and consumable costs (ink and pretreatment). The GTX print driver can create an .ARXP file showing ink usage prior to printing.
-
What is the washability of a GTXpro print?Washability of a properly cured GTXpro print is similar to a properly cured, waterbased screen-printed shirt. Innobella Textile inks have been tested by the AATCC to provide washability of 4.0 or greater.
-
Does this work with PC or Mac computers?The GTXpro print driver can be installed on both PC and Mac. PC should run Windows 8.1 (64-bit) or Windows 10 (64-bit). Mac should run macOS 10.14 Mojave or macOS 10.15 Catalina.
-
How is DTG printing different from screen printing?Screen printing requires more upfront work (separating artwork, creating screens, registering screens) and suits larger runs or designs with limited colors; it's not ideal for printing over seams, zippers or pockets. DTG printing jets ink directly onto the substrate without touching the garment, prints higher-detail images with unlimited colors, and is designed for short-to-medium runs and photographic quality.
-
What is pretreating? When do I do it?Pretreating prepares a garment for white-ink printing by preventing ink absorption into the fibers. The pretreatment fluid creates a chemical barrier that causes a reaction with white ink, allowing it to sit on top of fibers as a good underbase for CMYK inks. It's usually applied with an automatic pretreater for uniform coverage, then cured on a heat press for 35 seconds at 356°F with heavy pressure. Some users also pretreat garments printed with CMYK only on polyester, blends, or cotton to make colors pop more.
-
Does it print on any type of garment material?When using white ink (printing on dark-colored fabric), 100% cotton is recommended. When using color ink only (printing on light-colored fabric), 100% cotton and blends up to about 50% polyester are recommended.
-
Is Wi-Fi supported?No, Wi-Fi is not supported.
-
Where can I purchase a GTX printer?GTX printers are sold through authorized dealers in each country/region. Please check the official website for details and contact information.
-
Is the GTX manufactured by Brother?Yes. Including the inks and print heads, the GTX is manufactured at Brother's Kariya factory in Aichi, Japan.
