1. The importance of selecting high-quality DTF film
DTF film is the carrier medium in the digital transfer process. The pattern is sprayed onto the film through ink and finally transferred to the substrate through thermal transfer technology. Therefore, the quality of DTF film directly affects the transfer effect, color performance, stability and adhesion of the pattern.
Surface coating of film High-quality DTF film usually has a uniform coating, which can ensure that the ink is evenly attached to the surface of the film and stably transferred to the target substrate during the transfer process. The coating of the film helps to improve the adhesion of the ink and reduce problems such as uneven color, unclear pattern or shedding during the transfer process. The coating quality of ordinary films is unstable, which may cause the ink to adhere loosely, causing the pattern to fade, fall off or peel off.
High temperature resistance of the film The pattern needs to be transferred to the substrate by hot pressing during the DTF transfer process, which requires the DTF film to have good high temperature resistance. High-quality DTF film can usually withstand high temperatures without deformation or melting, ensuring the stability of the transferred pattern. If the film has poor temperature resistance, it may cause deformation of the film during the transfer process, affecting the quality and firmness of the pattern.
Transparency of the film Transparency is an important factor in the selection of DTF Pet Film Roll. High-quality DTF films usually have higher transparency, so that the details of the pattern can be more clearly displayed during the transfer process. Films with poor transparency will affect the performance of ink spraying, reduce the vividness of the color, and cause the pattern to become blurred.
Thickness and flexibility of the film The thickness and flexibility of the DTF Pet Film Roll also determine the quality of its transfer effect. Although the thin film is easy to operate, it may affect the adhesion of the pattern; while a too thick film may cause uneven adhesion of the pattern and even wrinkling. High-quality DTF films have appropriate thickness and flexibility, which can ensure the integrity and transfer quality of the pattern, and will not break or deform during use.
2. The importance of choosing high-quality ink
As the "color source" of pattern transfer, the quality of DTF ink directly determines the color performance, durability and smoothness of the transferred pattern. Choosing the right ink can ensure that the pattern is more vivid, delicate, and has a longer service life.
Type of ink: Pigment ink vs. Dye ink
Pigment ink: Pigment ink is the most commonly used high-quality DTF ink with strong color saturation and excellent light stability. The pigment particles in pigment ink can firmly adhere to the surface of the substrate and are not easily detached or faded due to external factors such as friction and washing. Therefore, the patterns transferred using pigment ink are bright in color and have strong anti-fading ability, suitable for long-term use and washing.
Dye ink: Dye ink usually has high color brightness, but poor light resistance and washability. Dye ink is usually suitable for short-term use applications, but for products that require long-term use and frequent washing, pigment ink is more suitable.
Adhesion and durability of ink High-quality DTF ink has good adhesion, which can ensure that the ink is firmly attached to the film and keeps the color bright for a long time after transfer. Low-quality ink may have insufficient adhesion, causing the pattern to gradually fade or fall off during washing or use. In addition, high-quality inks usually have better wear resistance, sun resistance and UV resistance, which can effectively improve the durability of the transferred pattern.
Ink particle size and stability High-quality DTF ink has uniform particle size, which can ensure the fineness and stability during spraying. If the ink particles are too large or uneven, the printed pattern particles will be rough, affecting the color reproduction and pattern clarity. In addition, high-quality ink is not prone to precipitation or agglomeration during long-term storage, which ensures the stability of the printing process.
Environmental protection With the increasingly stringent environmental regulations, choosing environmentally friendly inks has become a market trend. High-quality DTF inks usually meet environmental standards, do not contain harmful substances, and are harmless to the human body and the environment. Choosing environmentally friendly inks not only helps to comply with regulatory requirements, but also enhances the brand image and attracts consumers who pay attention to environmental protection.
3. How to choose high-quality DTF membranes and inks
Brand selection When choosing DTF membranes and inks, it is recommended to choose well-known brands and certified suppliers. These brands usually provide high-quality products with stable performance and excellent transfer effects, and can provide perfect after-sales service.
Sample test Before purchasing in bulk, small batch sample tests can be used to verify the compatibility of membranes and inks. The test content can include the color effect after transfer, the adhesion of the pattern, durability and washing test, etc., to ensure that the final product meets the quality standards.
User Reviews and Feedback Checking user reviews and industry feedback can also help understand the actual performance of the film and ink. By understanding the usage experience of other customers, you can effectively avoid buying low-quality products.
Technical Support and After-Sales Service It is also very important to choose a supplier that provides technical support and perfect after-sales service. A good supplier can provide customers with operation guidance, solve technical problems that arise during the transfer process, and help customers achieve the ideal transfer effect.
