Many factors in Air Waybill can affect the quality of the printing process. In addition to the machine itself, there are substrate inks and external factors such as air humidity.

However, when a print operator encounters a practical problem in production, it is often not easy to quickly find the source of the problem and effectively solve the problem. Now we will help you sort out and answer common questions in the printing process. Paper wrinkles during printing, uneven paper stacks Air conditioners are insufficient or paper waves and static electricity can easily cause wrinkles. Incorrect feeder settings and paper transport settings may cause the paper to wrinkle. Paper is very sensitive to humidity fluctuations. Know that the humidity is 50% to 55%. Temperatures from 20 ° C to 220 ° C are ideal for paper transport and storage. This ensures that the paper remains flat during the printing process. Incorrect machine settings (such as the feeder settings) can also cause wrinkles in the paper. For example, the front gauge is not set correctly. The side tension is too large. The cardboard is too heavy.

Improper air setting above the rollers can cause the Air Waybill Printing to wrinkle. In addition, poor tooth transfer or bite pads are too dirty, too much printing pressure or uneven left and right is also the cause of wrinkling of the paper. Solution: Try to choose high quality flat paper. Check and adjust the front gauge correctly. The sideboard cannot be set too low. Reduce the leading edge of the cardboard. Carefully adjust the paper feed pressure. Pay special attention to the paper. Enter the bite position.
