As we all know, there are many factors that affect quality in the printing process. In addition to the machine itself, there are substrates, ink, and external factors such as air humidity and workshop temperature. However, when the printing operator encounters actual problems in production, it is often not easy to quickly find the source of things and effectively solve the problem. Now, we will help you sort out and answer common questions in the printing process. Wrinkled paper In the printing process, the paper stacking is not smooth, the air conditioner is insufficient, the paper edge is wavy and static electricity, etc., it is easy to cause the paper to wrinkle. Incorrect feeder settings and paper transport settings can also cause paper wrinkling. Paper is very sensitive to humidity fluctuations. It is important to know that an environment with a humidity of 50% to 55% and a temperature of 20 ° C to 220 ° C is most suitable for paper transportation and storage, which can ensure that the paper remains flat during the printing process. Paper wrinkling may also be caused by improper machine settings (such as Feida settings). For example, the front gauge setting is incorrect, the edge gauge pulls too much, the platen presses too hard, the leading edge blows too strong Improper blower settings above the printing cylinder will wrinkle the paper. In addition, poor tooth transfer or dirty pads, excessive printing pressure, or uneven left and right are also causes of paper wrinkling. Try to choose high-quality and smooth paper. Correctly check and adjust the front and side rules. The pressure board can not be set too low. Reduce the front edge of the conveying board. Blow the air carefully.
