However, its color depth is relatively strong, and it is suitable for printing products with relatively single color and simple graphics and text.

The printing ink of the curved offset press is relatively thin, the three-dimensional effect is poor, and it is easy to fall off. However, it can print rich colors, which is suitable for more complex graphics and texts with various colors.

Both screen printing machines and offset printing machines in curved printing equipment have their own advantages and disadvantages. They are used in different fields.
