Toy water stickers are mainly designed for irregular products. For example, most printing techniques are much better, and the quality of the produced products is more guaranteed. We usually see some patterned products made by water transfer printing, but there are often some problems during the water transfer printing process, such as white spots and unclear patterns. What are the reasons for this? Let's take a look together:
The pattern on the toy water sticker is unclear:
1. The water temperature is too low, causing the activator to evaporate too slowly and the activation time to be too long.
2. The activator is too strong or sprayed too much.
3. The soaking time of the water transfer film is too long.
4. Low oil is not dry enough.
5. The transfer film is unclear.
White dots:
1. The air flow in the environment is too fast, which accelerates the volatilization of the activator and ultimately leads to its failure.
2. The water temperature is too high, causing the activator to evaporate too quickly and become ineffective. The activator switch of the spray gun is too small, and the number of guns is too few and uneven.
No technology can be perfect. In order to avoid this drawback, we print images and text into repetitive patterns that do not have actual shapes and do not affect their appearance after deformation, greatly reducing costs. The toy water sticker processing machine has precise tension automatic control
