Commonly Used Paper Cup Printing Process

1. Offset printing Offset printing is an advertising paper cup that uses the principle of oil and water repulsion to print paper cup patterns. The advantage is that the color of the pattern is full, vivid, and clear. Even the small lines printed on the paper cup can be clearly displayed, which makes the appearance of the whole paper cup more beautiful. However, the paper cups printed in this way are not suitable for use in the edible industry, and the offset printing ink is not very environmentally friendly, so the paper cups printed in this way are better not to be used for drinking water.
2. Silk screen printing has good flexibility and applicability, and is more suitable for printing on soft items such as paper or cloth, and can also be printed on hard items, such as glass, ceramics, etc. This method of printing will not be limited by the shape and size of the surface of the substrate, and the paper cup printed by screen has certain limitations in terms of processing gradients and image accuracy.
3. Flexo printing is also known as green printing because flexo printing is a water-based ink. When it comes to flexo printing, the structure of the machine is relatively simple, and the investment scale is relatively low. Compared with other types of printing methods, flexo printing is a printing process commonly used in the printing of advertising paper cups.
