Many people attempt to hydro dipping at home, but some problem always occurs. In this article, TSAUTOP will tell you why do you hydro dipping failure and give you a relative solution at the following points.
1. Pattern with wrinkles
If your hydro dipping finished product has been printed with your selected pattern, but there are wrinkles in the pattern. Because water transfer printing film doesn’t have enough dissolution time, you can solve this problem by delaying the dissolution time of hydro ink dipping film for a better 3D water printing effect.
2. The pattern is blurred
If there is an occasion in which your water transfer printing products have a blurred pattern, which expresses your hydro dipping paper dissolution time is exceeded, please shorten dissolution time in the process of liquid ink hydrographic.
3. The pattern flows
The pattern will flow, if you spray activator B excessively during the process of water-ink transfer printing, reducing the amount of activator sprayed can solve the problem.
4. The pattern is not printed completely
There are several reasons for incompletely painting of speed shape of items: uneven activator spraying, high environment temperature or high water temperature, over fast evaporation of activator.
Spray the activator evenly, lower the temperature of the water, adjust a comfortable room temperature, or prevent high wind from coming into the room to avoid the activator evaporated.
If you have enough budget for your hydro dipping business, I suggest you realize TSAUTOP hydro dipping tank, which has an automatic spray system and water recirculation system, can avoid this incomplete hydro printing problem perfectly.
5. Blisters on products’ surface
If you find there are blisters on the finished products’ surface, then your activator does spraying is not enough and the product has a wrong angle to get into the water to do water transfer ink printing. So please adjust the activator does and change the direction and angle of the product entering into the water.
6. Poor adhesion of pattern after hydro dipping
If your material has oil on the surface or the primer is wet, the finished product will occur poor adhesion of pattern after water transfer inkjet. So please make sure the material is cleaned thoroughly, primer is dry as well pay attention to whether you have done well about points 2 , 3 , 4 as above.
7. Material is blistering or cracking after topcoat is applied
If there are blisters and crack on the material’s surface after topcoat is applied, which express that the material has low solubility and the drying time is too short after the primer is applied. You should choose another topcoat solvent to replace the old one or delay the drying time of the primer for a better liquid ink hydrographic effect .
8. Poor adhesion of the topcoat
If topcoat can not be bonded with the material, maybe primer and topcoat do not match or topcoat does not match material. You should choose other paint to replace them.
9. Topcoat painted yellow after drying
a. Drying time is too long and over high temperature also will cause this situation. If you lower the temperature and shorten the drying time setting on your drying tunnel machine, but this situation does not have any improvement, please replace this yellow paint.
b. Thick and uneven topcoat painting at the corner of the product, will also cause the topcoat painted yellow after drying. If you want to solve this problem, it is OK to reduce the amount of topcoat spraying.
This solution can help you solve the above problems in hydro ink transfer. I wish this article can help you make perfect hydro dipping products with your love water transfer film.
