1. Offset Printing
Offset printing is based on the repulsion of oil and water, the image and text are transferred to the substrate through the blanket cylinder. Full bright color and high definition are the two most significant advantages to offset printing, it allows the paper cup looks more beautiful and delicate no matter if there are gradient colors or small tiny lines on the cups.
2. Screen Printing
Screen printing has great flexibility and applicability for its soft mesh. It can not only be used in paper and cloth but also is popular in glass and porcelain printing and no need to worry about substrate shapes and sizes. However, when talking about printing on paper cups, screen printing is obviously limited by the gradient color and image accuracy.
3. Flexo Printing
Flexo printing is also called “green painting” because of the water base ink it used, also it has become a trending method in many companies. Compared to the huge body of the offset printing machines, we can say the flexo printing machine is “thin and tiny”. In terms of cost, the investment in a flexo printing machine can be saved by 30%-40%, that’s one of the most important reasons for attracting small businesses. The printing quality of paper cups depends largely on the pre-press production, although the color display of flexo printing is slightly inferior to offset printing, it is still the main process used in paper cup printing at present
4. Digital Printing
Digital printing is based on digital tech to produce high-quality printed matter. Unlike traditional methods, it doesn’t need any blanket cylinders or meshes, which makes it an efficient choice for businesses and individuals who need prints in a quick time. The only downside is that it is slightly more expensive compared to other prints.
