In this article, we take a closer look at direct-to-garment printing – its strengths and weaknesses, how it works, and which fabric is the best to print on.

We also provide some practical tips for creating a successful direct-to-garment design and explore some of the best print-on-demand products that are the perfect canvas for dtg printing.

What is DTG printing?

Direct-to-garment (DTG) printing is an innovative method for producing t-shirts, utilizing advanced digital printers to apply eco-friendly, biodegradable inks directly to fabric surfaces. Unlike traditional methods, DTG transfers inks directly without the use of intermediaries like screens or paper.

Recent advancements in DTG technology have enabled printers to achieve exceptional color accuracy and sharper resolution, accommodating a wider range of fabrics, including cotton, polyester, and blends. Natural fibers like cotton still yield the best results, but improved pre-treatment processes now enhance print quality on synthetic blends.

DTG stands out for its environmental benefits; it uses sustainable inks and supports on-demand production, reducing waste by allowing printing in any quantity, from single units to bulk orders. The latest dtg printers are more cost-effective, making high-quality printing accessible to small businesses and entrepreneurs globally without the need for ownership.

These innovations ensure that DTG remains a versatile, sustainable, and efficient choice for custom apparel printing.

Advancements in technology

Today, DTG technology is more efficient and accessible thanks to breakthroughs in ink development, printing equipment, and design software. Modern DTG printers offer precise, full-color prints with intricate detail and faster production speeds, eliminating the need for manual color separation and screens. This advancement empowers creators with unlimited design possibilities, completely transforming customization in apparel.

With these technological leaps, DTG printing offers unparalleled quality and personalization, making it a cornerstone of the modern custom apparel industry.

Types of DTG printers in the market and the materials and inks used in them

direct to garment (DTG) printing technology has advanced significantly, resulting in a wide range of high-performance printers. The best DTG printer for you depends on your business needs, requirements, and budget.

Entry-Level DTG Printers: Ideal for beginners or small businesses, these cost-effective options, such as the Epson SureColor F2100 and Brother GTX Pro, offer high-quality printing. They may have slightly slower speeds and a more modest color gamut but are perfect for starting out.

Mid-Level DTG Printers: For those needing faster turnaround times, models like the Anajet mPower and ColDesi's M2 provide enhanced print consistency and a broader color range, making them practical for growing businesses.

Industrial DTG Printers: Designed for high-volume production, industrial printers such as the Kornit Avalanche HD6 and Epson F3070 deliver top print quality, speed, and consistency, ideal for established industry professionals.

Regardless of type, all DTG printers use eco-friendly, water-based inks. These inks are formulated for both light and dark garments and provide artists with unlimited color options. DTG printing remains versatile, accommodating various fabrics with optimal results on 100% cotton, while also performing well on cotton blends and polyester.

How does DTG printing work?

Direct-to-garment printing works by applying inks directly to t-shirt fabrics, in contrast to methods that apply inks indirectly using screens or paper. It does this by using a modified type of Inkjet Printer that can print water-based inks known as aqueous inks.

To apply these inks, DTG printing uses a four-step process:

- Prepare digital art files

- Pretreat and cure the t-shirt

- Print on the t-shirt

- Cure the ink

Let's break down these steps:

1. Preparing digital art files

DTG printers apply inks using a pattern based on a digital file. Direct-to-garment printing software works best with formats such as PSD and PNG that support transparent backgrounds, but it also accepts other common graphics file formats such as JPG and TFF.

Graphics design programs such as Photoshop that use these programs usually use color models based on red, green, and blue (RGB). In contrast, DTG printers use models based on cyan, magenta, yellow, and black (CMYB). To manage this format difference, DTG printing software uses Raster Imaging Processor (RIP) software to convert RGB files into CMYK files.

2. Pretreating and curing t-shirts

According to All Print Heads, the type of ink used by DTG printers works best with natural fibers such as cotton, bamboo, and hemp. To ensure the ink displays correctly, DTG uses a pretreatment machine before printing a t-shirt. Pretreatment applies a liquid solution that keeps white ink from soaking into the shirt and discoloring it while also preventing it from smearing or mixing with colored inks.

After the pretreatment solution has been applied, it is cured with a heat press or air dryer to make the t-shirt printing surface flatter. Fibers such as cotton normally stick up. Curing flattens the fibers to provide a smoother surface for printing.

3. Printing on t-shirts

After pretreatment, t-shirts are readied for DTG printing by placing them on a flat platform called a platen. The platen holds the t-shirt in place to keep it flat and aligned in the right spot for inks to be applied. T-shirts can be aligned correctly to platens by lining up their neck collar, shoulder seams, or side seams on shirts that have them. Once a t-shirt has been aligned on a paten, it can be printed by feeding the paten into the printer.

4. Curing ink

After a t-shirt has been printed, the ink must be cured to affix it to the garment properly and ensure durability through repeated washings. Curing may be done with a heat press or forced air dryer.

DTG vs. screen printing: Which printing method is better?

Choosing the right printing methods for your custom apparel can be tricky. Here’s a quick breakdown of DTG and Screen Printing to help you decide.

Choose the printing method that best suits your business by considering your specific needs.

Tips for your first DTG design

DTG printing allows great precision in image reproduction, meaning you can go as complex as you like regarding colors and details in your designs.

Here are some practical direct-to-garment printing tips to help get you started on the right foot: 

1. Understand your design software: Knowledge of popular graphic design software like Adobe Illustrator or Photoshop is crucial. Invest some time to learn how to create gorgeous, detailed designs.

2. Experiment with colors and textures: Direct-to-garment printing excels with designs that have many colors and complexities. So, go ahead and experiment with your palette. Complex gradients, large detailed images, and intricate designs can all be achieved effortlessly.

3. Consider the material: Direct-to-garment printing performs best on 100% cotton material. If you plan on printing on a blend, keep in mind that the ink may not adhere as well to the non-cotton fibers.

4. Invest in quality equipment: While this might seem evident, it's worth repeating. Quality machines will deliver superior results and stand the test of time.

5. Test prints: Before mass printing, always make a test print. This will ensure that your design appears exactly how you imagined on the fabric.

6. Maintenance is key: Regular maintenance of your DTG printer will ensure its longevity and keep it running smoothly. Regular cleaning can prevent clogs and other common problems.
