What is TPU UV Printing?
TPU UV printing (also known as UV print on TPU) is an innovative UV printing process that cleverly combines the direct printing capabilities of a UV flatbed printer, UV curing technology, and DTF heat transfer technology.
Its core principle is not to print directly on textiles but to create high-quality patterns using flexible TPU film, which are then transferred to textile fabrics via heat pressing. This TPU film not only carries the pattern but also serves as a durable, highly adhesive, and flexible protective layer on the fabric surface, providing scratch resistance and a 3D effect.
Steps for UV Printing on TPU Material
Step 1: Design the Pattern
Use professional design software (such as Photoshop) to create or edit your pattern, paying attention to size, positioning, and resolution.
Step 2: Print the TPU Film with a UV Flatbed Printer
Use a professional UV flatbed printer (such as the KJ-1060UV flatbed printer) to print the pattern directly onto the TPU film with high resolution and precision, then cure the UV ink quickly using UV lamps.
Step 3: Cutting the Pattern
Use a laser cutter to automatically and precisely cut the pattern, saving time and effort.
Step 4: Heat Press the Pattern and Transfer it to the Textiles
Place the cut TPU pattern over the textile (such as T-shirts, sportswear, hats, backpacks, waterproof fabrics, etc.). Then, apply specific temperature and pressure using a heat press machine to permanently transfer and adhere the pattern from the TPU film to the textile surface.
This process breaks free from the traditional UV printing technology’s reliance on substrate hardness, achieving a transition from rigid substrates to flexible textiles.
In addition, the TPU material itself has strong flexibility, wear resistance, and chemical corrosion resistance. When combined with UV ink, it further enhances the pattern with a 3D three-dimensional effect and durable adhesion.
The Main Differences Between UV TPU Printing, Screen Printing and HTV Printing

Advantages of 3D Relief UV TPU Printing for Textiles
Compared with traditional textile printing processes (such as screen printing, heat transfer vinyl (HTV), direct to garment printing (DTG), or direct to film printing (DTF), the TPU UV printing solution offers significant and unique advantages through UV flatbed printer:
Excellent 3D Effect and Touch
UV flatbed printers can accurately stack white ink and varnish layers. This means that you can easily create 3D embossed effects, raised textures, or localized glossy/matte areas on TPU film.
This strong visual and tactile 3D effect is difficult to achieve with screen printing and ordinary DTF heat transfer.
Superior Washability and Durability
The cured UV ink itself has excellent adhesion and wear resistance. Combined with the flexibility, tear resistance, and weather resistance of the TPU film itself, the patterns printed by TPU UV printing exhibit outstanding washability and are not easy to crack or fade. A critical feature for textiles that require frequent washing.
Significant Cost and Efficiency Advantages
Compared with screen printing, TPU UV printing eliminates the high costs and long plate-making time, making it ideal for small orders, personalized customization, and fast printing needs.
Compared with HTV (heat transfer vinyl), color-by-color cutting and then heat pressing, TPU film is printed directly on the UV flatbed printer, completing all colors and effects at one time, greatly simplifying the printing process and improving efficiency.
Unparalleled Color Expression
Compared with HTV and screen printing of single or four-color printing, UV flatbed printers offer a wide range of ink color combinations, enabling a wide color gamut and delicate color gradients. making TPU UV printing on textiles show excellent color expression, meeting your needs for vibrant patterns on textiles via UV printing.
Enhanced Environmental Friendliness
Today’s UV flatbed printers all use energy-saving UV-LED curing technology. In addition, UV ink does not contain volatile organic compounds (VOCs), and the curing process has almost no odor emissions, which is more environmentally friendly than solvent-based inks.
Application of UV Print on TPU
TPU UV printing technology is rapidly being applied to multiple textile-related industries, providing new ideas for personalized decoration and special effects of clothing.
Sports and Outdoor Apparel
Compared with DTF clothing printing technology, applying UV TPU printing technology to the field of sportswear is an innovative solution. It can print stretch-resistant, wear-resistant, and washable team logos, numbers, sponsor logos, etc., on high-performance sportswear, jerseys, outdoor jackets, waterproof clothing, and other fabrics, which are more durable and long-lasting.
Casual Clothing
You can create personalized 3D patterns on T-shirts, sweatshirts, hoodies, jeans, and jackets, adding unique decorative elements to clothing. It can also replace the flat effects of DTF printing or DTG printing on clothing, especially when dark clothing and special texture effects are required.

FAQ
What types of fabrics are suitable for TPU UV printing?
Almost all common textile fabrics are suitable, including cotton, polyester, nylon, spandex, waterproof coated fabrics, etc. For high-elasticity fabrics (such as swimwear fabrics), UV TPU printing can also be used.
What is the difference between UV printing on TPU material with UV flatbed printer and heat transfer vinyl printing(HTV)?
Compared to HTV printing, TPU UV printing offers more vibrant colors, stronger 3D effects, and better washability.
HTV (heat transfer vinyl):
This method primarily uses pre-coated vinyl film, cut into patterns using a cutting machine, then heat-pressed onto garments. Color options are limited (mostly single or simple colors), and producing multi-color or complex patterns is inefficient.
TPU UV flatbed printing:
Directly prints 3D effect patterns on specially designed TPU film using a UV flatbed printer, then transfers via heat pressing. Advantages include outstanding texture effects, a wide range of fabric applications, washability, and high efficiency for printing small batches of multiple designs.
Are TPU UV printing garments washable? How many times?
Yes, washability is a key advantage of TPU UV printing.
High-quality TPU UV printing, when properly operated, can typically withstand over 50 washes in a household washing machine without noticeable cracking, peeling, or significant fading.
Its actual lifespan far exceeds that of ordinary direct-to-garment printing (DTG), approaching or exceeding that of high-quality screen printing and HTV printing. However, the specific number of washes depends on factors such as TPU film quality, ink, heat transfer process, fabric type, and the washing method.
