DTG printing: What is direct to garment printing?

What is DTG printing and how does it work?

DTG (Direct to Garment) printing is a modern method of marking garments by directly applying a print to the fabric. This relatively new technology is revolutionizing the textile personalization market, offering high quality and versatility. Digital DTG involves the use of specialized printers adapted to print directly on garments, much like traditional inkjet printers print on paper.

In the DTG direct printing process, a special print head applies ink directly to the fabric fibers. DTG printing on clothing is made using digital technology, which allows for precise reproduction of even the most complex graphic designs with an accuracy of at least 300 DPI. This is a fundamental difference from traditional printing methods such as screen printing, where each color requires a separate stencil.

Direct DTG printing on garments involves several key steps:

1. Preparation of graphic design in digital form
2. Pre-treatment of garments (pretreatment) - especially important for dark materials
3. Apply an undercoat of white ink (for dark fabrics)
4. Printing the right design in CMYK colors
5. Fixing the print using a heat press or drying tunnel

Where will DTG printing work well? Materials and applications

DTG technology will work best on cotton or high cotton content materials. DTG printing on cotton T-shirts gives the best results, as the natural cotton fibers absorb the ink perfectly, ensuring the durability and vivid colors of the print. Possibilities for using this marking method include:

• Cotton shirts and t-shirts
• Sweatshirts and sportswear
• Canvas bags
• Hats and textile accessories
• Interior design elements (pillowcases, curtains)

It is worth noting that while DTG printing works great on cotton, it can also be done on some polyester-blend fabrics, but with some limitations on color intensity and durability. For polyester fabrics, sublimation, another garment marking technique, is often a better choice.

Advantages of DTG printing

High quality and detail

One of the biggest advantages DTG printing is the ability to produce extremely detailed and colorful prints. Digital technology makes it possible to produce designs with smooth tonal transitions, shading and photographic image quality. Digital printing DTG offers great color reproduction, which is difficult to achieve with traditional printing methods.

Personalization and small print runs

DTG printing is cost-effective even for single garment pieces, making it ideal for:

• Custom clothing personalization
• Production of small design series
• Testing new designs before mass production
• Creating unique gifts

Unlike screen printing, which is only economical for larger runs, DTG allows personalization of single copies without high prepress costs.

Speed of execution

Direct DTG printing allows for fast turnaround, which is especially important for urgent orders. The entire process from design to finished product can be completed in a matter of hours, while traditional garment marking methods require much more preparation time.

Environmental friendliness

Compared to other printing techniques, DTG is relatively environmentally friendly. Mainly water-based inks are used, which contain fewer harmful chemicals than the inks used in screen printing. In addition, the process requires less water and generates less waste.

Limitations and disadvantages of DTG printing

Costs at high expense

Although DTG printing is economical for small runs, it can be less cost-effective than screen printing for larger runs. This is due to the cost of inks and the time it takes to produce each print.

Material limitations

As I mentioned earlier, the DTG method works best on cotton fabrics. Printing on fabrics with a high polyester content or synthetic fabrics may not be as durable and crisp. In addition, dark or colored fabrics require an additional primer of white ink, which increases the cost and lengthens the manufacturing process.

Durability of printing

Although DTG prints are quite durable, if proper washing rules are followed for printed garments, they may not be as durable as those made by screen printing or flock transfer. After many washes, gradual color fading is possible, especially if the garments are not properly cared for.

DTG printing vs. other garment marking methods

DTG vs screen printing

When comparing DTG printing with screen printing, the following differences are worth noting:

DTG vs. other digital techniques

There are also other methods of digital garment marking on the market, such as:

• Sublimation - ideal for polyester fabrics
• Digital transfer (reflect) - allows printing on various materials
• DTF (Direct to Film) printing - a relatively new technology that combines the advantages of DTG and transfers

Each of these techniques has its own unique advantages and limitations, so choosing the right method for marking garments should be tailored to the specific project, material and expected result.

Practical applications of DTG printing

Fashion and custom clothing

DTG printing has found widespread use in the fashion industry, especially in the segment of personalized clothing and small design runs. It allows designers to create unique designs without ordering large runs.

Promotion and marketing

Companies are increasingly using direct DTG printing to create:

• Corporate clothing
• Promotional gadgets
• Materials for events and trade fairs
• Limited edition advertising products

E-commerce and print on demand

One of the fastest growing printing applications DTG is a "print on demand" business model, where products are printed only after an order is placed. This business model makes it possible:

• Minimize inventory
• Elimination of risks associated with unsold inventory
• A wide range of designs without the need to maintain them physically
• Personalization of products according to customer preferences

How to choose the right DTG printer?

When choosing a printer for DTG printing, there are several key aspects to consider:

Equipment quality and experience

Guaranteed high quality printing depends largely on the quality of the equipment used. A professional printing house should have modern DTG printers and appropriate technological facilities.

Portfolio and samples

Before placing an order, it is a good idea to ask for samples of previous work or examples of work from a portfolio. This will allow you to assess the actual quality of prints and the experience of the printer.

Project handling

Good A printing company offering DTG printing services should provide comprehensive Project operation, including:

• Consultation on the preparation of graphics
