Tips | What is the applications difference between DTF inks and direct inkjet pait ink ?
1. The process is different
The application of DTF (offset heat transfer) is that the ink is printed on the heat transfer film, and then a layer of hot melt powder is sprinkled on the surface of the heat transfer film, and then the color is developed by pressing; while the application of direct inkjet paint ink is directly printed on the fabric, and the fabric is in the printing process. In order to achieve better color and color fastness, it is often necessary to use pre- and post-treatment liquids together. The process is more complicated than the DTF heat transfer process, and more professional customers are often required to complete the entire coating direct spray program. The DTF(offset heat transfer) process is relatively simple, the client is easy to quickly master the process, easy to copy and popularize, which is also an important reason why the DTF heat transfer application scheme is so popular.
2. The feel is different
Direct spray application of paint feels better than DTF offset heat transfer. There is a layer of hot-melt powder between the ink and the fabric in the DTF offset heat transfer application. The hot-melt powder is transferred to the fabric as a binder and ink together. The ink for direct injection of paint is directly printed on the fabric, so there is generally no problem of hand feeling. In terms of feel, the direct spray application of paint has obvious advantages. On the other hand, with the maturity of the application of the DTF offset heat transfer process, the application performance of hot melt powder has been improved, and the feel of the finished product made by the DTF offset heat transfer application can also meet the needs of market customers.
3. Different color expression and fastness
DTF Offset heat transfer applications are superior in terms of color expression and fastness. In order to improve the color and fastness of coating direct spray application, it is often necessary to cooperate with pre- and post-treatment liquids to achieve better results, while the use of hot melt powder in DTF offset heat transfer application perfectly solves the problem of color and fastness. The hot melt powder is used as a binder to perfectly combine the DTF ink and the fabric, and the color expression and fastness performance after color development are very good. The color and fastness problems that are very troublesome in the application of direct injection of coatings, through the use of hot melt powder as an intermediate medium, the DTF ink and the fabric can be well matched, which perfectly solves the long-standing problem of color and fastness in the application of direct inkjet printing. .
4. The cost of the plan is different
At present, Epson 4720 nozzles are still the main application machines for DTF offset heat transfer applications, while industrial nozzles are the main applications for direct inkjet printing applications, and the machine costs for the two applications are quite different. In terms of ink price, the price of DTF offset heat transfer ink matching the 4720 machine is also cheaper than that of paint direct-injection printing application ink. The cost of the DTF offset heat transfer application solution is the heat transfer film, and the price of the heat transfer film is also constantly dropping. On the whole, the cost of the DTF offset heat transfer application program is lower than that of the direct spray printing application. DTF Offset heat transfer application scheme has low investment threshold, simple process, easy entry and replication, so it develops rapidly and becomes popular in a short period of time.
