Things You Need To Pay Attention In Bulk Water Transfer Printing Processing?

1. Storage conditions of WTP film

The transfer WTP film must be kept at a room temperature of about 25 degrees, with humidity below 70%, and cannot be exposed to direct sunlight.  

2. Water Temperature

The water temperature of the hydro dip tank is kept between 25-30 degrees, with a constant temperature dipping tank to do transfer processing, the water surface should be kept in the overflow state. 

3. Always keep the water clean  

The water surface should be kept clean and free of activator residues and other impurities from the impregnating film. You should always keep the water clean so that the items to be hydro-dipped are well dipped in the following process. 

4. Laying down the WTP Film should in a slightly oblique angle

The hydrographic dipping film should be placed flat on the water surface at a slightly oblique angle so that no air bubbles are formed between the hydrodynamic dipping film and the water surface.

In this process, please pay attention to the hydro dipping film can not be put back.  

5. Dissolution time of the hydro dip film

The temperature of the water used to dissolve the film is generally between 25-30 degrees, and it takes about 1 minute for its dissolution.
