Problems solved by technology

At present, silk screen printing or "adhesive" printing methods are usually used. The disadvantages of these traditional printing methods are obvious. First, a large amount of harmful substances will be produced during the printing process, which will adversely affect the surrounding environment. After completion, the effect of printing cannot be maintained for a long time

The second is that the content to be printed needs to be plate-made before printing, and once the content is changed after printing, it needs to be re-made, and each plate-making needs to be made in a professional factory, which wastes time and increases costs

In addition, traditional printing machines are usually installed in factories, which are bulky, inconvenient to move and difficult to operate
