Have you ever wondered how T-shirts get those bright, detailed designs? DTG ink is the secret! In this guide, we’ll explain what DTG ink is, how it works, and why it’s excellent for printing on fabric.
What Is DTG Ink?
DTG ink (Direct-to-government ink) is a water-based ink made for printing designs directly onto fabric. Unlike other inks that sit on top of the fabric, DTG ink soaks into the fibers, making the print soft, smooth, and colorful.
Why DTG Ink Is Special
- ✔ Water-based & eco-friendly – Safe for clothing and the environment.
- ✔ Soft & flexible – The design feels like part of the fabric.
- ✔ Bright & detailed – Perfect for colorful, high-quality prints.
- ✔ Long-lasting – When cured properly, it won’t crack or fade..
How Does DTG Printing Work?
DTG printing works like an inkjet printer but for fabric. Here’s how:
- Pre-Treatment – A special liquid is applied to help the ink stick better.
- Printing – The DTG printer sprays ink onto the fabric.
- Curing the Ink – Heat is used to dry and set the ink, making it permanent.
This method allows for detailed, multi-color designs without extra setup.
DTG Ink vs. Other Printing Inks
| Feature | DTG Ink | Screen Printing Ink | DTF Ink | Sublimation Ink |
|---|---|---|---|---|
| Best For | Cotton & blends | Large bulk orders | Polyester & blends | 100% polyester |
| Feel on Fabric | Soft & smooth | Thick & slightly raised | Thin & flexible | Becomes part of the fabric |
| Color Quality | Very high | Moderate | Very high | High |

👉 DTG is best for cotton fabric, while other inks work better on polyester or bulk orders.
Best Fabrics for DTG Ink
