What is DTG Printing?

DTG stands for Direct-to-Garment. It is a digital inkjet printing method that applies water-based inks directly onto fabric — most commonly cotton t-shirts — using a modified inkjet print head. Think of it as a regular inkjet printer, but instead of feeding paper, you slide in a t-shirt.

The result is a soft, breathable, full-color print that becomes part of the fabric rather than sitting on top of it like a vinyl transfer. Designs can include unlimited colors, photographic gradients, fine details, and complex artwork that would be impossible or prohibitively expensive with traditional screen printing.

DTG printing is the engine behind the modern print-on-demand (POD) industry. Services like Printful, Printify, Merch by Amazon, and Redbubble all rely on DTG at their core. But you don't need to work through a third party — owning a DTG machine puts that capability directly in your hands.

How Does DTG Printing Work?

DTG printing involves a series of precise steps. Understanding the process helps you manage quality and avoid common mistakes — especially when printing on dark garments.

Pros & Cons of DTG Printing

DTG printing is powerful, but it's not the right solution for every situation. Here's an honest breakdown of the benefits and limitations:

DTG vs. Other Printing Methods

How does DTG stack up against the alternatives? Here's a side-by-side comparison of the most common garment decoration methods:

The bottom line: DTG wins on flexibility and short-run economics. Screen printing wins on high-volume unit cost. DTF (Direct-to-Film) is an increasingly popular hybrid that combines much of DTG's flexibility with better polyester compatibility — many modern machines, including IEHK's lineup, combine both in one unit.

What Can You Print With DTG?

DTG is primarily designed for flat, fabric-based items. The most common products include:

Best fabric: 100% ring-spun cotton gives the sharpest, most vibrant DTG results. Cotton-polyester blends (up to 50/50) work well. Pure polyester requires specialized inks or a DTF transfer instead.

Dark vs. light garments: White and light-colored garments are the easiest to work with — no pre-treatment needed, and colors appear as expected. Dark garments require a white ink underbase and pre-treatment solution to make colors pop.

Who Should Use DTG Printing?

DTG printing suits a wide range of business models. Here are the most common use cases where it excels:

Print-on-demand shops. If you're running an Etsy store, a Shopify store, or any e-commerce brand that fulfils orders individually, DTG is your backbone. No inventory risk — print when an order comes in.

Custom apparel businesses. Corporate uniforms, event merchandise, band merch, sports teams, school clubs — any client that wants custom-branded clothing in small-to-medium quantities is a perfect DTG customer.

In-house brand merchandise. Restaurants, cafés, gyms, and hospitality brands that sell or give away branded apparel benefit from having a DTG machine on-site — producing items on demand at a fraction of outsourced cost.

Event & festival printing. Live, on-site personalized printing is a growing market. With a compact DTG machine, you can print custom shirts at markets, concerts, pop-ups, and trade shows in minutes while customers watch.

Sample and prototype production. Fashion designers and clothing brands use DTG to produce sample runs before committing to bulk screen-print orders — saving thousands in screen setup costs.

How Much Does DTG Printing Cost?

DTG printing costs fall into two categories: the cost of owning a machine, and the per-print production cost.

Machine cost: Entry-level DTG printers start around $1,500–$2,500 for compact A4 models suitable for small business use. A3-format machines for full-front t-shirt printing typically range from $2,200–$5,000. Industrial high-speed units scale upward from there.

Per-print cost: For a white t-shirt with a simple design, direct ink cost is often $0.50–$1.50. A full-coverage dark shirt with white underbase typically runs $2–$4 in ink. Factor in pre-treatment solution, blank garment cost, electricity, and wear on consumables for your true cost of goods.

Additional equipment: A heat press or conveyor dryer is required for curing — budget $200–$500 for a quality heat press. Pre-treatment sprayers or automated pretreaters add further cost at scale.

Break-even analysis: At a selling price of $20–$35 per custom shirt and a COGS of $6–$10 (including blank + ink + overhead), a DTG machine can pay for itself in several hundred shirts — achievable in weeks for an active seller.

Tips for Getting the Best DTG Print Quality

Use high-resolution artwork. Always start with artwork at 300 DPI or higher at the final print size. Low-res files produce blurry, pixelated prints — no amount of software correction can recover lost detail.

Pre-treat consistently. Uneven pre-treatment application is one of the most common causes of patchy prints on dark garments. Use a consistent spray pattern, and always press the pre-treatment dry with a heat press before printing.

Cure properly — every time. Under-curing is the #1 cause of premature fading after washing. Follow the ink manufacturer's recommended temperature (usually 160°C/320°F) and dwell time. A non-contact infrared thermometer helps verify actual garment temperature.

Run the printer daily. DTG print heads clog easily when left idle. Even on quiet days, run a nozzle check and cleaning cycle to keep white ink circulating. White ink in particular settles quickly and can block channels permanently if neglected.

Wash test before selling. Always run a wash test when changing garments, inks, or settings. Wash the printed garment inside-out in cold water and check for fading or cracking before committing to a full production run.
