Garment printing encompasses two primary methods: heat transfer printing and direct-to-garment (DTG) printing. In this article, we will focus on direct-to-garment printing, which is a relatively new technique in the garment printing industry. As the name suggests, this method involves printing directly onto the fabric of a garment. DTG printing utilizes a purpose-built printer, similar to a modified, larger version of the commonly available inkjet printer. Instead of paper, these printers smoothly pass garments through the printing process. Connected to a computer, the printer employs specialized software known as RIP software. This software enables color management, produces white underbases, and facilitates the use of a higher volume of ink, which is essential for direct-to-garment printing.
During the early stages of DTG printing, it was only possible to print on white or lightly colored garments, as white ink was not readily available. However, as technology advanced, the printing industry evolved as well, and now white ink is as accessible as the traditional CMYK colors. This development has expanded the versatility of direct-to-garment printing, allowing for printing on dark-colored garments. On dark garments, the white ink creates a mask layer, upon which the colored ink is then printed, resulting in full-color, high-quality prints on various items such as t-shirts, hoodies, and polo shirts. The printed design on the garment is smooth, flush with the fabric, and provides what is referred to in the industry as an excellent “hand” or feel.
For optimal results with DTG printers, 100% cotton garments are preferred, although some of the newer printers are now capable of producing equally good prints on polyester or polycotton fabrics.
After the printing process is completed, it is crucial to bond the ink onto the fabric using a heat press. This step takes little more than a minute but ensures that the ink is cured, allowing the garment to be worn and washed without the risk of the design fading or washing away.
The quality of DTG printers is exceptional; however, it is important to consider the price when considering purchasing one. These printers typically range in price from £10,000 and upwards.
Like any printing method, there are advantages and disadvantages to using direct-to-garment printing. Let’s explore these advantages:
- No setup costs: Since the process prints files directly from the computer, there are no initial setup expenses.
- Time-saving: Unlike screen printing, where multiple screens are required for each color, DTG printing can complete the printing process in one run, saving valuable setup time.
- Ideal for small runs: DTG printing is highly suitable for smaller orders.
- No color or design limitations: DTG printing allows for unlimited colors and intricate designs.
- Quick turnaround: Depending on the order size, DTG printing offers a fast turnaround time.
- Efficient process: The entire process, from start to finish, takes minutes rather than hours.
- Consistent color management: DTG printing ensures consistent color management and print precision. The garment is not handled as much as in screen printing, reducing the potential for errors.
However, it is important to be aware of the disadvantages of DTG printing:
- Cost: DTG printers are expensive, resulting in higher garment prices.
- Ink expenses: Particularly white ink can be costly.
- Printer maintenance: DTG printers require daily cleaning and proper maintenance to maintain a high standard of print quality.
- Space requirements: Due to their size, DTG printers require a decent amount of workspace.
In conclusion, DTG printers offer exceptional quality, and if budget permits, investing in one can be beneficial for both businesses and customers. When it comes to prints from DTG printers, it is challenging to find better quality output.
