After DTF T-shirt Printing, the Pattern Loses Powder?

After DTF T-shirt Printing, what should I do if the pattern delaminates, is not fine, feels dry and does not adhere? This should be a problem that many customers have experienced. However, the cause of most problems is not bad ink, but these details in the printing process are not done well!

1. Whether the printing ink volume matches the curing parameter setting

Too high ink volume will cause the surface of the pattern to fail to fully cure, and it is easy to bubble or delaminate during subsequent hot pressing; improper printing parameter settings are one of the common causes of pattern powder loss and delaminate.

Solution:

Optimize the ink volume: According to the complexity of the pattern and the material properties, adjust the ink volume to ensure that the ink can fully cover the pattern. Tips: It is recommended to do 2~3 small sample tests before starting the machine to confirm that the DTF T-shirt Printing  state is stable.

2. Is the stacking order of DTF transfer ink and color ink correct?

The order of ink layers affects the pattern forming effect and adhesion performance. Solution 1. The correct order should be: white ink for base → color ink for coloring 2. Optimize printing parameters (1) White ink thickness: Ensure that the thickness of white ink is moderate. If the white ink is too thin, the pattern will not be able to cover the color. If the white ink is too thick, it will not dry easily. It is usually recommended to be between 20 and 30 microns. (2) Color ink thickness: The thickness of color ink is usually between 10 and 20 microns. Ensuring bright colors and rich details.

3. Whether the heat pressing time, temperature and pressure settings are accurate

Improper heat pressing control directly affects whether the pattern can be firmly attached to the clothes.

Solution 1. The specific time needs to be adjusted according to the material and the complexity of the pattern. 2. Adjust the heat pressing pressure: Ensure that the heat pressing pressure is moderate. Tips: It is recommended to record the best parameters for each film material to avoid arbitrary adjustments that affect stability. If the film material thickness is different or the machine power is different, the parameters should be fine-tuned appropriately.

4. Is the DTF PET film used suitable for the current process?

Good ink + good pattern, if it is matched with inferior film material, it is still easy to peel off! Its quality and adaptability directly affect the adhesion and durability of the pattern. The quality of PET films on the market varies. Some films have insufficient temperature resistance and weak peeling force. If the coating quality of the transfer film is poor or uneven, it may cause the pattern to fail to adhere firmly during the hot pressing process.

Solution 1. Choose a well-known brand and a PET film that has been verified by the market to ensure its quality and performance. Coating uniformity: Make sure the coating of the PET film is uniform and free of defects or unevenness. Compatibility test: Before formal production, conduct a small batch test to ensure that the PET film is compatible with hot melt powder and ink. 2. Check the shelf life of the transfer film (1) Shelf life: Expired transfer film may cause the coating performance to deteriorate and affect the printing effect. (2) Storage conditions: Make sure the PET film is stored in a dry, cool environment and avoid moisture or high temperature.

The development of DTF technology is accelerating the “customization on demand” model. However, the stability of the printing effect is the core of customer repurchase.
