The direct-to-garment (DTG) printing method is a modern, multi-color technology that revolutionizes custom apparel. It functions like a high-end inkjet printer, except it is for fabric. The process involves applying ink directly onto the material. This makes it excellent for original designs with intricate detailing, multiple colors, and even photographic images. In addition, it enables you to order products in small quantities with no minimum requirements.
According to industry experts, the direct-to-garment (DTG) printing method is highly recommended for t-shirts, hoodies, and other clothes made from natural fibers. This guide targets clothing brand startups, fashion designers, and anyone who wants to create superb, high-quality custom pieces. We’ll walk you through the entire process of DTG printing clothes from start to finish.
What Exactly is DTG Printing? A Look Under the Hood
Understanding DTG printing technology helps you appreciate its quality and versatility. It is a digital process. The design file you upload gets directly translated onto the finished clothing item.
The Mechanism: An Inkjet Printer for Fabric
Think of your regular desktop printer that prints on paper. A Direct-to-Garment (DTG) printer does the same for fabric. These are not desktop machines, though. Professional shops use Industrial DTG printers like the Epson F3070, which are built to ensure precision and high output.
These printers use specialized, water-based aqueous inks. Unlike screen printing inks that sit on top of the fabric, DTG inks work differently. They are designed to be absorbed by the garment’s fibers, which results in a very soft feel, especially on light-colored apparel.
The Step-by-Step DTG Printing Process
Bringing a digital design to life on a t-shirt involves a precise, multi-step process. Here’s how professional DTG printing clothes works:
-
Pre-treatment: First, the garment gets sprayed with a pre-treatment liquid. This clear, non-toxic solution is crucial, especially for dark garments. It creates an optimal printing surface and helps the water-based inks bond chemically with the fabric fibers for maximum vibrancy and durability.
-
Curing the Pre-treatment: The garment goes on a heat press for a short period. This step dries the pre-treatment solution. It creates a perfectly prepared canvas for the ink.
-
Printing: The shirt or hoodie is carefully smoothed onto the printer’s platen to ensure a flat surface. The machine then prints the digital design directly onto the fabric, applying all colors in a single pass. For dark garments, it first lays down a white ink underbase. Then it adds the colors on top.
-
Final Curing: Once printing is complete, the garment returns to the heat press. This final curing process bonds the ink permanently into the fabric. It makes the garment wash-fast and ready to wear.
DTG vs. Screen Printing: Which Method Should You Choose?
Choosing between DTG and screen printing is one of the most common decisions for anyone creating custom apparel. Each technique has its own pros and cons. Your choice will depend on your design, order quantity, and desired final appearance.
Key Differences Summarized
This table breaks down the core differences. It helps you quickly assess which method fits your project.
| Feature | DTG Printing | Screen Printing |
|---|---|---|
| Best for | Complex, multi-color designs, photos, small orders | Simple designs with few colors, large bulk orders |
| Color Count | Unlimited colors and gradients at no extra cost | Priced per color; best for 1-4 solid colors |
| Feel on Fabric | Very soft, breathable feel as ink soaks into fibers | Heavier feel as ink sits on top of fabric |
| Durability | Good; lasts 50+ washes, fades softly over time | Excellent; very durable, can sometimes crack over time |
| Cost-effectiveness | Best for small runs (1-25 items) and one-offs | Best for large runs (50+ items) due to setup costs |
| Setup Time | Minimal; upload a file and print | Extensive; requires creating a separate screen for each color |
| Fabric Compatibility | Best on 100% cotton; works on some blends | Very versatile; works on cotton, blends, polyester |
When to Choose DTG Printing Clothes
Use a DTG printing service for your clothes when your project involves:
- Complex designs with many colors, intricate details, gradients, or photorealistic images.
- Small order quantities, from a single sample to a small batch for your startup.
- Print-on-demand fulfillment where you need to print items as they are ordered.
- A desire for a soft-hand feel where the ink is part of the fabric, not on top of it.
- A need for a fast turnaround on a small number of items.
When Screen Printing is the Better Option
Screen printing remains the industry standard for certain applications. Consider it when:
- Your design is simple, with one to four solid colors (like a text-based logo).
- You are placing a large bulk order (typically 50 or more units). The cost-per-item becomes significantly lower.
- You need the absolute brightest colors possible, especially on dark-colored garments.
- You need to print on 100% polyester or other synthetic fabrics.
- You want specialized effects like glitter or dimensional puff prints.

Your Decision-Making Framework: Is DTG Right for Your Project?
Beyond a simple comparison, this framework will walk you through the key factors so you can confidently decide if DTG printing clothes is the right choice for your specific needs.
Step 1: Analyze Your Design’s Complexity
First, look at your artwork. Does your design include a photograph, a detailed illustration with many colors, or subtle gradients and shading? DTG is the clear winner because it can reproduce these details with incredible accuracy.
Is your design a simple one- or two-color logo? Both methods are technically possible. At this point, your decision will hinge on the next two steps.
Step 2: Determine Your Order Quantity
This is often the most critical factor. Are you testing a new design with a run of 10 shirts? DTG printing is your most cost-effective option as there are no setup fees.
Are you ordering 100 hoodies for a company event? Get quotes for both methods. The per-unit price for screen printing will almost certainly be lower. The upfront cost of creating screens is spread across the large quantity, making it more economical at scale.
Step 3: Check Your Garment’s Fabric
DTG printing technology performs best on natural fibers. Is your garment 100% ringspun cotton? DTG will produce a vibrant, high-quality print.
Are you using a 50/50 cotton-polyester blend? DTG can still work, but the colors may appear slightly less saturated, giving it a more “vintage” or heathered look. For 100% polyester apparel, you will need to explore alternative methods like screen printing or sublimation.
The Bottom Line: A Quick-Check List
Answer these questions about your project:
- My design has more than 5 colors or includes gradients.
- I am ordering fewer than 25 items.
- My garment is made of 100% cotton.
- I need to print just one sample before committing to a larger order.
If you checked two or more boxes, then DTG printing clothes is very likely your best bet.
The Insider’s Guide: Preparing Artwork for a Perfect DTG Print
The quality of your final printed garment is directly tied to the quality of the digital file you provide. Poor artwork is a common cause of disappointing results. To get a perfect print, follow these guidelines.
Resolution: The 300 DPI Rule
Resolution is measured in DPI, or Dots Per Inch. Images on the web are typically 72 DPI. This looks fine on a screen but will appear blurry and pixelated when printed on a shirt.
The golden rule is to create your artwork at a resolution of 300 DPI at the exact size you want it printed. A 10-inch wide design should be created in a 10-inch wide, 300 DPI file.
Color Mode: RGB for DTG
Traditional print design for paper often requires CMYK color mode. DTG printers are different. They’re calibrated to work best with RGB (Red, Green, Blue) files. Submitting your artwork in RGB ensures the most accurate color translation from your screen to the final garment.
File Formats: Go for PNG
We strongly recommend saving your final, print-ready file as a PNG (Portable Network Graphics). The PNG format is ideal because it supports high resolutions and, most importantly, transparent backgrounds.
A transparent background is essential if you are printing on any color other than a white shirt. It ensures that only your design is printed, without an unwanted white or black box around it. Reputable custom DTG printing services always emphasize this in their guidelines.
Best Garments and Fabrics for DTG Printing Clothes
Choosing the right garment is just as important as the artwork you create. The fabric’s composition and weave significantly determine how the ink is absorbed and affect the final design’s appearance.
Why 100% Ringspun Cotton is the King Material
For the absolute best results with DTG printing, always choose garments made from 100% ringspun cotton. The “ringspun” process creates a tighter, smoother, and more uniform fabric surface. This provides the perfect canvas for the DTG printer, allowing for sharp details and vibrant, consistent color absorption.
Printing on Cotton Blends and Other Fibers
While 100% cotton is ideal, DTG can also be used on cotton/polyester blends, like 50/50 or 80/20 hoodies. However, the water-based ink only bonds with the cotton fibers. The print on a blend will have a slightly faded, retro appearance.
Garments made of 100% polyester are generally not suitable for DTG printing. The water-based inks cannot properly adhere to synthetic polyester fibers, resulting in a dull, faded, and non-durable print.
Light vs. Dark Garments: The Underbase Factor
Printing on light-colored garments (white, grey, pastels) allows the ink to soak directly into the fibers. This results in a print with virtually no feel.
Printing on dark garments (black, navy, forest green) requires an extra step. You need to print a white ink “underbase” first. The colored inks are then printed on top of this white layer. This makes the colors pop but adds a slight texture to the print. This is why the pre-treatment process is non-negotiable for achieving a quality print on dark apparel.
Caring for Your DTG Printed Clothes: A Longevity Guide
Proper care is crucial to maximize the life and vibrancy of your DTG printed apparel. High-quality DTG prints are durable, and following these steps will ensure they look great for years.
The First 24 Hours: Let it Cure
The ink is cured with heat immediately after printing. However, we advise against washing the garment for at least 24 hours. This allows the ink to fully set into the fabric fibers.
Washing and Drying Best Practices
To protect your investment, follow these simple washing instructions:
- Turn inside out: Before washing, always turn the garment inside out. This protects the printed design from abrasion caused by other clothes in the wash.
- Wash cold: Use cold water on a gentle cycle. Hot water can cause both the garment and the print to fade over time.
- Mild detergent: Avoid using bleach, fabric softeners, or other harsh chemicals. A mild detergent is all you need.
- Tumble dry low or hang dry: High heat from a dryer is the biggest enemy of any printed apparel. For best results, hang the garment to dry. If you must use a dryer, choose the lowest heat setting.
A Note on Ironing
Never iron directly on the printed area. If you need to iron the garment, make sure it is turned inside out. Use a low heat setting, avoiding prolonged contact with the print area.

Frequently Asked Questions (FAQ) about DTG Printing Clothes
1. How durable is DTG printing?
When produced by a quality provider and cared for properly, a DTG print is very durable. It can easily last for 50+ washes. Unlike some thick prints that crack and peel, a DTG print tends to age gracefully with the shirt, developing a soft, vintage feel over its lifespan.
2. Can you feel the ink on a DTG printed shirt?
On light-colored garments, the ink is absorbed directly into the fabric, making the print exceptionally soft and breathable with almost no feel. On dark garments that require a white underbase, the print has a slightly more substantial feel. However, it is still significantly softer and more flexible than a traditional screen print.
3. Is DTG printing eco-friendly?
Yes, DTG is widely considered a more sustainable printing method than traditional screen printing. It uses non-toxic, water-based inks and generates very little waste. The ink is applied precisely and only where the design calls for it, avoiding the large amounts of water and chemicals required for screen creation and cleanup.
4. What is the biggest mistake people make with DTG printing?
The most common and critical mistake is providing a low-resolution image file. Submitting a 72 DPI image found online will result in a pixelated, blurry, and unprofessional-looking print. For sharp, clear results, you must always start with a 300 DPI file designed at the intended print size.
5. Is DTG printing expensive?
The cost of DTG printing is relative to your order quantity. For a single custom shirt or a small run (under 25 pieces), DTG is the most affordable method because it has no per-color or setup fees. However, for large bulk orders (50+ items), the per-item cost of screen printing becomes much more economical.
