[Descrição sumária]The proper storage of cardboard significantly impacts its production performance, particularly in terms of temperature and relative humidity. The typical relative humidity range for cardboard is between +50% to -10%. Exposure to excessively humid or hot environments can lead to registration errors and decreased paper feeding performance. To prevent such issues, printing factories can take the following measures: keep cardboard wrapped until ready for use; place wrapped cardboard in the workshop at least 24 hours in advance to acclimate to workshop temperature; humidify packaged printed cardboard before processing and shipping. Additionally, humidity control devices can be utilized. Curling and peeling of cardboard are also common issues, especially for uncoated cardboard. Moreover, small impurities sandwiched between paper stacks, pressure during paper stacking, and blade pressure during precutting can all damage cardboard. Defective cardboard may still produce printing waste through the rubber blanket and concave roller protection of the printing machine. Therefore, prevention is more cost-effective than remediation afterward. When using uncoated cardboard, printing factories should carefully select inks, control text height, and design to extend drying time and prevent problems. Inks with high oxidation and pigment content are suitable for filling the uneven surface of uncoated cardboard. Decreasing text height or using alcohol dampening can effectively prevent emulsification of printed products. Printing samples on coated paper first and then printing and tracing them on uncoated paper may exceed the actual capacity of the cardboard.
