The details of ’Differences between DTF ink and DTG‘
In this article, let's talk about the differences in the application of coating hot stamping ink and heat transfer ink. A friend in the background sent a private message to the editor asking about the differences in the application of offset hot stamping ink and coating direct injection ink. In response to this question, we will provide a detailed analysis.
Before analyzing, let's first talk about several terms currently used in the market for coating hot stamping ink. Some introductions refer to offset hot stamping ink, while others refer to film transfer ink. In fact, offset hot stamping ink and film transfer ink have a relatively wide range of names, and coating hot stamping ink will be more straightforward, mainly emphasizing the application of coating hot stamping. To put it bluntly, in the two applications of offset hot stamping and cotton cloth direct spraying, both belong to the application of paint ink. So what are the differences between these two applications?
The biggest difference between the two applications is that the process is different. The offset hot stamping application involves printing ink on top of the hot stamping film, then spreading a layer of hot melt powder on the surface of the hot stamping film, and then applying color by pressing and ironing; The application of direct spray paint ink is directly printed on the fabric. In order to improve color and color fastness during the printing process, the fabric often needs to be used in combination with pre and post treatment solutions. The process is relatively complex compared to hot stamping, and often requires more professional customers to complete the entire direct spray paint scheme.
The offset hot stamping process is relatively simple. The client is easy to quickly master the process, and easy to copy and popularize. This is also an important reason why the paint hot stamping application scheme is so popular. Due to the difference in the application process described above, the difference in hand feel is definitely better for direct coating applications.
This is because there is a layer of hot melt powder between the ink and the fabric in offset hot stamping applications. The hot melt powder serves as a binder and is transferred onto the fabric with the ink, resulting in a relatively poor natural feel compared to direct coating applications. The application of direct spraying of paint with ink is directly printed on the fabric, so there is generally no problem with hand feel. In terms of tactile properties, direct spraying of coatings has a significant advantage.
On the other hand, with the maturity of the application of offset hot stamping technology, the application performance of hot melt powder has improved, and the finished feel produced by offset hot stamping application can also meet the needs of market customers. The color expression and fastness are different. In terms of color expression, the application of offset hot stamping is better, and similarly, in terms of fastness, the application of offset hot stamping performs better.
In order to improve color and fastness, direct spraying of coatings often requires a combination of pre and post treatment solutions to achieve better results. However, the use of hot melt powder in offset hot stamping applications perfectly solves the problems of color and fastness. As an adhesive, hot melt powder perfectly combines paint ink and fabric, resulting in excellent color expression and fastness performance after coloring.
The color and fastness issues that are very challenging in direct coating spraying applications are solved by using hot melt powder as an intermediate medium to ensure a good fit between the coating ink and the fabric, perfectly solving the long-standing problems of color and fastness in direct coating spraying applications. The cost of the solution is different. Currently, the main machine used for offset hot stamping is Epson nozzle, while the main machine used for direct coating is industrial nozzle. The machine cost difference between the two applications is significant. In terms of ink price, the offset hot stamping ink of the matching machine is also relatively cheaper compared to the ink used for direct coating application.
The most expensive offset hot stamping application solution is the hot stamping film, and the price of the hot stamping film is also constantly decreasing. Overall, the cost of offset hot stamping application solution is relatively lower than that of direct coating application. The application scheme of offset hot stamping has a low investment threshold, simple process, easy entry and replication, so it has developed rapidly and become popular in a short period of time.
The above is the difference shared with friends about the application of offset hot stamping and direct spray paint. Currently, both solutions belong to the digital application of paint, and each has its own advantages and disadvantages. There are still significant differences in market positioning and customer base.

Paint hot stamping will definitely become the mainstream solution in personalized applications, while cotton cloth digital printing will still be mainly based on paint direct spraying application. The two solutions complement each other and will become the backbone of the rapid development of the entire paint digital printing.
