Toy printer is unique in many printing industries. The toy industry mainly uses UV printer to increase the beauty and personalization of toys. It mainly prints some materials that ordinary printers can't print, so it has its particularity. Toy printer is not omnipotent. It also faces some practical problems in printing technology. Let's talk about it briefly below.

1. Price of UV printer ink

Although UV ink has the advantages of instant curing and good conjunctival performance, the price is relatively expensive, and special UV blanket and UV ink roller must be used, which greatly increases the cost of the product;

2. Adhesion of UV printer ink

In the curing process of UV ink, the internal components are crosslinked and polymerized, and the instantaneous change produces large internal stress, which affects the adhesion of the ink to the substrate. Although this problem can be improved by surface treatment or modification of the substrate, the fundamental solution is to seek and develop UV ink with good adsorption performance, low shrinkage stress and low price;

3. Suitable fountain solution for UV printer ink

UV ink is mainly used in non absorbent printing materials, and the ink configuration is different for different printing materials. Therefore, UV printer requires that the fountain solution has a wide adaptability to ensure the required printing quality.
