DTG Printing on Dark Shirts: Techniques for Vibrant Results

Printing on dark-colored garments is one of the most exciting yet challenging aspects of DTG (Direct-to-Garment) printing. Without the right techniques, your prints may look dull, washed-out, or completely fail to show up. But with a few smart adjustments, you can produce vibrant, professional-quality prints that truly pop.

In this guide, we’ll cover everything you need to know to master DTG printing on dark shirts—from pretreatment to white ink layering and curing.

Why Printing on Dark Garments Is Different

Unlike light-colored shirts, dark garments require a white ink underbase so your design colors can stand out. Think of it as priming a black canvas before painting.

Skipping this step results in faded colors or invisible designs.

✅ The MTuTech DTG Printer is specially designed to handle white ink applications smoothly and consistently, making it ideal for dark garment printing.

Step-by-Step: How to Print on Dark Shirts with DTG

1. Choose the Right Garment

Start with:

● 100% cotton t-shirts

● DTG-optimized blanks (smooth, tight-knit fabric)

● Pre-shrunk fabric to prevent warping

Dark-colored cotton absorbs ink differently, so quality blanks make a big difference.

2. Pretreat the Garment Properly

Pretreatment is non-negotiable for dark shirts.

● Apply pre-treatment fluid evenly across the print area

● Use a pre-treatment machine for consistency

● Press the shirt under a heat press (160°C for 30–45 seconds)

● Let the shirt cool before printing

Too much pretreatment can cause staining or sticky patches—measure carefully (16–20 grams per shirt).

3. Use a Strong White Underbase

Set up your RIP software to:

● Lay down a solid white underbase beneath your full-color design

● Control ink density (100% for white, 80–90% for CMYK)

The white layer ensures your colors appear bright and bold on dark fabric.

4. Cure the Ink Correctly

After printing:

● Use a heat press or conveyor dryer to cure the ink

● Standard setting: 160°C (320°F) for 90–120 seconds

● Use parchment or Teflon sheets to avoid ink transfer

Under-curing leads to poor washability. Over-curing can damage the fabric or fade the ink.

5. Test and Calibrate Regularly

To ensure consistent results:

● Run daily nozzle checks

● Print test swatches with different white ink settings

● Check for banding, misalignment, or fading

● Store treated shirts in a dust-free, dry environment

Pro Tips for Vibrant Results

✅ Use high-resolution (300 DPI) artwork
 ✅ Avoid printing too close to seams or collars
 ✅ Adjust white ink levels based on shirt color (black needs more than navy)
 ✅ Store ink and pretreatment properly—avoid extreme temperatures

Common Mistakes to Avoid

❌ Skipping pretreatment
 ❌ Using poor-quality garments
 ❌ Incorrect white ink settings
 ❌ Not curing long enough
 ❌ Ignoring maintenance (leading to clogs)

Final Thoughts

DTG printing on dark shirts may seem tricky, but with the right equipment and workflow, you can produce vibrant, eye-catching prints that last wash after wash. Focus on pretreatment precision, white ink layering, and proper curing to get the best results.
