The direct offset printing process for corrugated boxes is already mature abroad. It is to directly print corrugated cardboard onto a special offset printing machine and is suitable for processing thin corrugated boxes.
This process can not only ensure the good formability of the carton, but also complete the exquisite facial paper printing, but the printing machine used is relatively expensive. In the next few years, this process may become a new development direction for high-end carton printing in China.
The screen printing corrugated box process uses direct printing. Since the ink drop rate of the screen is proportional to the pitch of the screen, the resolution of screen printing is not high, the image accuracy is low, and the number of conventional screen lines is 60 to 80 lines / inch.
The screen printing corrugated box has the following advantages:
â‘ The printing area can be large or small.
â‘¡The printing can be completed before the boxing, or after the boxing.
â‘¢ The ink color of screen printing is thick, the color saturation is high, and the visual effect is strong, especially the spot printing of spot color, the effect is better.
â‘£Easy plate making and low cost.
⑤ Low printing cost.
â‘¥ The printing quality is relatively stable.
The disadvantage of screen-printed corrugated boxes is that it is not suitable for linked production lines and the production efficiency is low.
Magnetic Whiteboard Sheets
Magnetic Whiteboard Sheets is one kind of flexible whiteboard. It is easy cut, bent, twisted, coiled, or can machined into almost any shape. So it can be roll up to saving space and carry easily.
Excellent Write-on and Wipe-off Durability
