Definition of DTG Druck

DTG stands for "Direct-to-Garment" and refers to a printing technique that makes it possible to print digital designs directly onto textiles. The DTG printing process is similar to that of a conventional inkjet printer, whereby special printers are used for textile printing.

Phases of the DTG printing process

1. Design preparation: The desired design is digitally created or digitized. RIP software is also required to convert the computer data of the design into comprehensible information for the printer.
2. Textile preparation: The textile to be printed is placed on a special printing table or printing plate.
3. Printing process: The DTG printer applies the ink directly to the textile, digitally reproducing the prepared design. The ink is absorbed directly into the fibers of the fabric.
4. Drying and curing: After the printing process, the printed textile is dried and the inks are fixed by heat to ensure a permanent bond with the fabric.

Advantages of DTG printing:

1. High print quality: DTG enables the printing of high-resolution, detailed designs with a wide range of colors.
2. Flexibility in color selection: There are no restrictions on the number of colors in the design, as the printer works directly from digital files.
3. Suitable for complex designs: DTG printing is well suited for complex, multi-colored or photorealistic designs.
4. Economical for small batches: Compared to some traditional printing processes, DTG is also economical for smaller production quantities.
5. Fast production times: The DTG printing process is relatively fast, which speeds up the production of printed textiles.

Disadvantages of DTG printing:

1. Cost per print: DTG printing can be more expensive than some other printing methods, especially for larger print runs. The initial cost of the printing machine is high and the cost per printed item is only suitable for small to medium sized jobs.
2. Restricted materials: DTG is best suited for cotton fabrics or materials with a high cotton content, as the ink adheres better to these materials. The adhesion of the ink is limited on synthetic materials such as most sports textiles.
3. Limited print size: DTG machines usually have a limited print area. Large print areas or oversizes can therefore be a challenge and may require multiple print runs.
4. Preparation time and maintenance: DTG printing requires careful preparation of the files and material. The machine also requires regular maintenance to ensure high print quality.
5. Wash resistance: Although modern DTG inks are often wash-resistant, they can fade easily on some textiles and printing conditions.
