What is DTG Printing and How Does It Work?
At its core, DTG—or Direct to Garment—printing is a technique that allows you to print intricate, full-color designs directly onto textile fabrics using specialized inkjet technology. But what does that really mean for you? Imagine being able to print a high-resolution photo or vibrant artwork straight onto a t-shirt, just like printing a picture from your computer—but onto fabric. That’s the power and simplicity of DTG Printing.
TL;DR: Here’s what you need to know if you’re just getting started:
- DTG Printing allows high-quality, full-color designs to be printed directly onto garments, typically cotton-based fabrics.
- It’s ideal for small batch production, on-demand printing, and custom t-shirts.
- Key steps include fabric prep, design placement, printing, and curing the ink.
- You’ll need proper maintenance routines to keep your DTG printer in good health.
- Common beginner mistakes include using the wrong fabric, ignoring pretreatment, or misaligning the garment.
Understanding Direct to Garment Printing
What is DTG Printing?
Direct to Garment (DTG) printing is the digital printing marvel that has revolutionized custom clothing—particularly t-shirts. Unlike traditional screen printing, which uses layered stencils to apply ink, DTG relies on a specialized inkjet printer to spray water-based inks directly onto the fabric. It’s perfect for jobs that require intricate details, gradients, or full-spectrum colors that are often difficult to recreate with other methods.
Benefits of DTG Printing
The primary perk? Flexibility. Whether you want to print a single design or fulfill custom orders with varied artwork, DTG is quick to set up and easy to personalise. Here’s why many are falling in love with this method:
- High-Resolution Prints: Photographs and complex patterns print beautifully.
- On-Demand Production: No minimums required. Ideal for small businesses or hobbyists.
- Eco-Friendly Options: Water-based inks are less harmful compared to plastisols used in screen printing.
- Soft Feel: Unlike screen prints, DTG designs become part of the fabric, not just sit on top.
Step-by-Step Process of DTG Printing
Preparing the Material
You know that saying, “Garbage in, garbage out”? It applies here too. The quality of your print largely depends on how well you prep the fabric. Most DTG jobs begin with 100% cotton garments, which naturally absorb the water-based inks. Before printing, pretreatment is applied—especially on dark-colored fabrics—to ensure ink vibrancy and wash durability.
Positioning the Garment
This may sound like a minor task, but it can make or break your print. The shirt needs to be loaded evenly onto the platen so the printed image aligns exactly where you want it. Even a 1 cm shift in placement can lead to crooked or off-center designs. Pro tip? Use alignment tools or a template board to get it right every time.
Printing the Image
With your garment correctly positioned and pretreated, the magic begins. The DTG printer works much like your home inkjet printer. It jets tiny droplets of ink onto the fabric, layer by layer. The printer takes care of the colors and shading automatically—but the outcome still relies heavily on the quality of your image file. Aim for at least 300 DPI and use transparent PNGs for best results.
Curing the Print
Once the print is complete, it’s not ready to wear just yet. The ink must be cured using a heat press or conveyor dryer to set the image permanently. Skipping this step—or doing it improperly—can result in cracks, fading, or poor washing durability. Typically, a heat press of 160°C for 90 seconds does the job, but always follow the ink manufacturer’s advice.
Tips for Successful DTG Printing
Choosing the Right Fabrics
Not all garments are created equal when it comes to DTG. Cotton is king for this process. Blends can work, but they often result in washed-out images and less durability. Go with ring-spun, combed cotton for that smooth printable surface. Avoid fabrics with heavy seams or uneven surfaces—they disrupt the inkjet nozzles and create splatter.
Maintaining Your DTG Printer
Ever owned a regular inkjet printer that clogs up if you don’t use it? DTG printers are similar—but even more temperamental. Regular maintenance is the difference between crisp prints and clogged nozzles. You’ll need to:
- Run daily nozzle checks and cleanings
- Shake your white ink cartridges (they settle fast)
- Keep the printer in a temperature- and humidity-controlled room
It’s a bit like caring for a pet—it needs attention, but it pays off with loyal performance.
Troubleshooting Common Issues
Here’s what often happens to beginners:
- Faded Prints: Usually from insufficient pretreatment or incorrect curing.
- Ink Bleeding: Common with polyblends or uneven pretreatment.
- White Ink Clogging: Manage this by daily shaking and priming routines.
- Ghost Images: Misalignments or static buildup can double-print an image.
Don’t get discouraged—DTG is part science, part craft. Every mistake teaches you something new.

Frequently Asked Questions
How much should a DTG print cost?
In Singapore, a basic DTG print may cost around $10 to $15. Premium prints with complex designs or high-end materials may cost $25 or more.
Can DTG printing be done on any fabric?
Not really. DTG works best on 100% cotton garments. Polyester blends can lead to poor color absorption and fading.
How long do DTG prints last?
With proper care, such as gentle washing and no tumble drying, DTG prints can last for over 50 washes without significant fading.
Is it worth buying a DTG printer for small businesses?
Yes, especially if you offer custom merchandise. However, factor in the cost of maintenance, ink, and training before investing.
Do I need to pretreat all garments?
Only dark garments or those requiring white ink need pretreatment. Light-colored shirts with CMYK-only designs usually don’t.
Can I print photographic images with DTG?
Absolutely. DTG shines when printing full-color, high-resolution photos. Just ensure the image is high-resolution (at least 300 DPI).
What are the disadvantages of DTG?
They include slow production speed for large orders, fabric limitations, and higher equipment maintenance compared to other methods.
