Definition of DTF printing
DTF stands for "Direct to Film" and is a modern printing technique that is mainly used for textile printing. This method makes it possible to print designs directly onto special transfer films, which are then transferred to the textile.
Phases of the DTF printing process:
- Design preparation: The desired design is digitally created or digitized using design software. RIP software is also required to convert the computer data of the design into comprehensible information for the printer.
- Printing on transfer film: The design is printed on a transparent transfer film using special inks.
- Powdering: Thermofixing powder is applied to the printed transfer film and sticks to it. Excess powder is removed.
- Drying and curing: The printed transfer film is dried using heat and the inks and powder are cured to prepare them for the transfer.
- Transfer to the textile: The printed transfer film is placed on the textile and connected to a heat source, typically a heat press.
Advantages of DTF printing:
- Versatility: Suitable for printing on a wide range of textiles, including cotton, polyester and blended fabrics.
- High print quality: Enables the printing of detailed designs with vivid colors.
- Small quantities: Compared to other printing technologies, DTF is also economical for smaller production quantities.
- Flexibility: Fewer restrictions regarding the number of colors compared to conventional screen printing processes.
- Rapid production: DTF printing enables printed textiles to be produced comparatively quickly.
Disadvantages of DTF printing:
- Durability and wash resistance: Compared to other printing techniques such as screen printing or flex printing, the durability and wash resistance of DTF prints can be lower.
- Complexity of the process: DTF requires the operation of several software programs and the combination and maintenance of several technical devices to achieve optimal results. This could be a major challenge for inexperienced users or smaller companies that are not familiar with the technology.
- Softness of the print: DTF printing can be perceived as less soft or flexible, especially compared to other printing methods such as screen printing.
- Need for white printing: DTF printing usually requires an additional step for white printing, especially when printing on dark or colored materials. This can complicate the process and increase production times.
