Best DTF Transfer Film for Your T-Shirt Printing

Reason:

The weather is humid, with high humidity and static electricity. If the edges of the pattern are shaking and not clean, it is necessary to check:

1. Is the environmental humidity too high or the temperature too low?

2. Is the power of the DTF shaker machine insufficient?

3. Whether powder application was delayed excessively after printing, causing drying and glycerol diffusion?

4. Is there flying ink on the nozzle?

Solution:

If it is found that the pressure wheel position is shaking unclearly or the blank area is shaking unclearly, it should be due to the influence of static electricity or the DTF rubber powder is damp or the DTF powder is too fine or the shaking force is insufficient. Measures should be taken according to the situation.

2. Generally, increasing the temperature of the heating plate and the receiving position of the shaking machine after printing, as well as increasing the shaking force, can help reduce the phenomenon of unclean edge shaking.

Reason:

High-temperature, short-time baking causes the water and glycerin in the ink to boil and evaporate violently, opening up the pores in the coating and film.

Solution:

It is best to use a mixture of medium and fine powders as the main component, with a small amount of coarse powder mixed in, or even none at all. A high-quality DTF dryer with a long drying cycle in both low and high temperature sections yields the best results. This allows for a gradual drying process, thoroughly evaporating the oil and water and melting the adhesive without causing a violent reaction.

The resulting DTF film is flexible, elastic, smooth, and well-dryed. If the DTF dryer is of slightly lower quality, utilize the preheating function of the heating plate to preheat and evaporate some moisture, thereby reducing the burden. It is advisable to dry the film slightly before applying the powder.

Reason:

The dried or transferred pattern may show oil or water seepage.

Solutions:

1. This problem is due to insufficient drying, preventing the water and glycerin in the printing ink from drying completely, resulting in backflow.

2. The drying capacity of DTF powder is also limited by the length of the dryer. Increasing the drying temperature slightly on the receiving plate before the powder baking machine can help evaporate the water and glycerin earlier.

Reason:

After DTF heat transfer, the coating peels off in the blank areas around the pattern.

Solution:

This is caused by excessive heat transfer pressure damaging the ink-absorbing layer on the film, or by the fabric surface paste easily sticking to the coating.

Generally, this can be easily solved by ensuring the temperature and heat transfer time meet the requirements for a firm adhesion, and by reducing the pressure as much as possible.

Reason：

This is attributable to an inadequate step design in the machine’s film-feeding mechanism, which fails to fully accommodate the functional requirements of single-sided film.

Solution：

The slipperiness of the single-sided film’s reverse side interferes with the equipment’s operational state. Typically, such machinery necessitates the use of double-sided film; once the friction provided by the matt-coated reverse side is engaged, normal operation is immediately restored.

Reason:

Temperature too high or heat transfer time too long.

Solutions:

Reducing the heat transfer temperature or shortening the heat transfer time.
