Introduction
When it comes to fabric printing, several technologies come into play: DTF (Direct-to-film), DTG (Direct-to-garment), Screen printing, and HTV (Heat Transfer Vinyl), among others. Each one serves the demanding industry trends.
For the modern textile printing industry, DTG printing is a great technique that brings intricate designs to life. Although it isn’t a new technology, having been around since 1996, it has undergone significant evolution over the years. Now, as one of the best on-demand printing technologies, it has been widely used to print high-quality, full-color designs on hoodies, shirts, sweaters, and more. However, it also has some downsides. You should be aware of the pros and cons to make an informed decision.
This article aims to provide you with in-depth information about this incredible printing technique, with its pros and cons discussed in detail. Let’s delve into the topic and gain further insights.
What is DTG Printing?
DTG, or Direct-to-Garment printing, utilises modified inkjet technology for direct printing on fabrics. The process is similar to that of inkjet printing, much like a standard paper printer. But instead, it works on clothing items such as t-shirts and hoodies.
The printer sprays aqueous inks directly onto the garment’s surface. The outcome is vibrant colours, intricate designs, and images that feel soft to the touch.
In contrast to other printing methods, such as screen printing, which requires building screens for each color in a design, this can be slow and costly for small batches. Comparatively, DTG is a quite simple method. It requires minimal setup, and the resulting designs and images are high-resolution, making it a perfect choice for low-volume custom orders. This method is particularly useful for the fashion industry, where trends change quickly and customization prevails.
Let’s take a look at how this method works.
How does DTG printing work?
Although you may come across various models of DTG printing equipment, the core process remains the same. So, here are the simple steps to the DTG printing method:
- Pre-treatment of Garments
Before printing starts, the garment must be pre-treated. This step is important for several reasons. It helps the ink adhere better for longevity and does not just sit on top. This also results in the vibrancy of color in a multi-colored, intricate design.
There are pre-treatment machines for DTG printing that simplify this step by automating the process, but it can also be done manually. The pre-treatment step involves spraying the specialized liquid evenly over the entire fabric. After that, the garment is pressed with heat to smooth the surface and make sure it’s ready for printing.
- Digital Design and Printing Process
Now, the design process starts after the fabric has dried completely after the pre-treatment process.
In this step, firstly, if using white/darker fabrics, an underbase is applied to enhance color vibrancy. Other than that, the garments are sent directly to the DTG printer for the printing process. It uses special software to print intricate patterns, designs, and images.
The inkjet printer sprays water-based inks onto the fabric, one tiny droplet at a time. This approach enables high-resolution images and vibrant colors. The DTG printer works similarly to an inkjet printer, which uses a color mix of cyan, yellow, black, and magenta.
- Curing and Finishing
After the design is ready, the garment is not yet ready to wear. You need to cure the ink. This step helps the garment last through washing and everyday use.
Curing is usually done by heating the garment in a conveyor dryer or using a heat press. Conveyor drying is suitable for large-volume manufacturing needs. However, a heat press is good for small businesses that work on customized orders.
Curing the designs helps the colors stay bright and makes the print more durable. After this step, the garment is complete and ready to wear or packaged for sale.
Types of materials suitable for DTG printing
The ideal substrate for use with DTG printing is natural fiber, although 100% cotton is the most preferred choice because it offers the best ink absorption and produces bright, detailed images. Ringspun cotton and combed cotton fabrics have become particularly popular, too. This is because of the smooth feel and high-quality prints. Blends of cotton with polyester may also yield good results, provided the cotton percentage is high.
Other natural fabrics, such as linen, hemp, and bamboo, require extra pre-treatment to be printed on and achieve bright, permanent images. Although pre-treatments developed in recent years have allowed printing on light-colored polyester and some synthetic blends, natural fibers continue to provide the brightest and longest-lasting DTG prints.
Pros of DTG Printing
Color Design and Quality
One of the incredible features of DTG printing is that it results in vibrant, high-resolution prints. DTG printers use advanced inkjet technology that allows for impressive color accuracy and fine detail. Other traditional methods, such as screen printing with color limits, or Heat printing, produce thick and plastic-like prints that feel unnatural. In contrast, DTF printing can recreate photo-realistic images, detailed artwork, and gradients smoothly. The fabric soaks the water-based ink that is directly sprayed onto it, so prints are vibrant and feel soft to the touch. Click here to see more differences between DTG and DTF printing.
Suitable for small batches and one-off designs
Because DTG is a digital process, setting up a print job is quick—just upload the design and print. There’s no need to make screens or plates, which are required for screen printing, and this saves time and cost. As a result, DTG is ideal for personalized items, such as custom t-shirts, merchandise featuring unique artwork, or prototypes. You can efficiently print as few as one garment, or easily switch designs between prints.
No Minimum Order Quantity
DTG is made for small businesses. You can offer on-demand printing services to your customers. Whether your order is one shirt or a dozen, there is no setup cost or obligation to large numbers. It is perfect to use in online shops where you receive small custom orders. Or in stores that would like to experiment with new designs, without having to put a lot of money at stake.
More environmentally friendly
Unlike some screen printing processes that use products containing harmful chemicals, DTG printing uses water-based inks. These inks are completely eco-friendly. They reduce the risk of polluting water systems. Since you print only as needed, it results in very little wastage of ink, fabric, and energy.DTG generates fewer wastes in general, enabling businesses to leave a smaller carbon footprint.
Easy to Use
Once pre-treatment is done, the printing process is simple. The machine handles everything. The operator simply places the garment, loads the design, and presses the print button. With the help of digital design software, even beginners can complete the process without any hassle. So, not only is the training time reduced, but you can manage the orders at a faster rate.
Cons of DTG Printing
Limited fabric compatibility
DTG works best on 100% cotton or high-cotton blends. But, it does not produce quality results with other materials such as Polyester, nylon, and some dark polyester blends. These fabrics do not absorb aqueous inks.
The prints they yield may appear faded or wash out fast. Darker fabrics also require more pre-treatment, which can complicate the process and impact consistency.
Higher unit cost and slow speed for large orders
Printing one shirt at a time is straightforward, but if you need hundreds or thousands of the same design, DTG is not cost-effective. The process is slower than screen printing, which uses a single design to print in bulk rapidly. This means each shirt takes several minutes, increasing costs and turnaround time for big orders. For mass production, screen printing or other printing methods often remain the more economical and faster choice.
Pre-processing and maintenance requirements
It is easy to print one shirt at a time, but when you require hundreds or thousands of the same design, it is not economical to use DTG. It takes longer than screen printing, which involves using a single design to print in large quantities at a time. This implies that every shirt requires several minutes, which raises both the cost and the fulfillment time of large orders. Screen printing or other printing techniques usually become more cost-effective and quicker when it comes to mass production.
Pre-processing and maintenance needs
All garments should be pre-treated prior to printing, especially those with darker colors. It is an additional process, if done manually, that is time-consuming and requires attention; it can destroy the print when not done or done hastily. Subsequently, printers require regular maintenance, including daily cleaning of print heads and proper handling of inks to prevent jams or clogging. Failure to maintain will result in defects in the prints, wastage of materials, and equipment downtime.
FAQs
How much does a DTG printer cost?
DTG cost prices vary. Beginner models range from $3,000 to $7,000 and are best suited for entry-level entrepreneurs. Mid-range professional machines cost between $7,000 and $15,000. Advanced high-end industrial DTF printers can be costly, and their price can go up to $30,000 or more.
How does a DTG printer work?
A DTG (Direct-to-Garment) printer sprays water-based inks directly onto fabric using inkjet technology. The process involves pre-treating the garment, printing the digital design onto the fabric, and then curing the ink with heat so it bonds to the fibers. The result is a high-resolution, full-color image printed right onto the garment.
How long does a DTG print last?
With proper care, such as gentle washing and avoiding harsh detergents, a DTG print typically lasts 40–50 washes before significant fading. Print life can vary based on fabric type, curing process, and washing habits. In many cases, the DTG prints can last as long as the garment.
Is screen printing better than DTG?
Screen printing and DTG each have strengths. Screen printing lasts longer, is more durable for bulk orders, and is better suited to simple designs with few colors. DTG excels at small runs and highly detailed, colorful graphics, but doesn’t last quite as long as screen printing. The best choice depends on your design type, the quantity of your order, and the substrate. See more differences between DTG and Screen Printing.
