The printing suitability of different paper boxes is quite different. If we do not take appropriate technological measures according to the material conditions, it will bring some problems to normal production. But even if the same type of paper products are used, the quality and printing adaptability of base paper will be different due to the differences in materials and processes between different brands or manufacturers. If some white cardboard, white cardboard and glass cards are acidic, ink drying is slow after printing, which will lead to difficulties in overprinting of semi-finished products and a significant increase in the rate of unqualified products; some low-grade white cardboard and glass cardboard have poor surface strength and are prone to quality failures such as powder dropping, hair dropping, foaming or delamination in the printing process.

　　由于印刷纸张多是由客户确定的，所以印刷企业往往处于被动迁就的状态。但即使面对的是客户为了降低成本而选择的不太令人满意的纸品，我们亦要在印刷工艺上进行精心的设计，以达到质量的尽可能提升。羿彩包装印刷厂经过多年的实践得出几点心得，愿与大家分享。

　　Because printing paper is mostly determined by customers, printing enterprises are often in a passive accommodation state. But even if we are faced with the unsatisfactory paper products that customers choose in order to reduce costs, we should also carefully design the printing process in order to improve the quality as much as possible. After years of practice, Yicai Packaging and Printing Factory has gained some experience, which I would like to share with you.

　　印刷偏酸的纸板，应采用快干快固着的油墨。

　　Printing acid cardboard should use fast-drying and fast-fixing ink.

　　对于表面强度差的纸板，应调整降低油墨的粘度，同时适当降低印刷的压力和印刷的车速。

　　For cardboard with poor surface strength, the viscosity of ink should be adjusted to reduce the printing pressure and speed.

　　若采用多色机组印刷且色组有多余，可将前色组空出来行空压印以去除纸粉、纸毛，避免或减少质量故障。

　　If the multi-color printing unit is used and the color set is redundant, the pre-color set can be emptied and air-imprinted first to remove the paper powder and wool, so as to avoid or reduce the quality failure.

　　对于印后要覆哑膜的产品，可不用选择过于昂贵的油墨，如高光油墨，因为高光油墨的大优势在于印刷墨层光泽度高，但是产品经过覆哑膜后会覆盖油墨层的高光泽度，所以将高光油墨用于覆膜产品会造成浪费。

　　For products with dumb film after printing, it is not necessary to choose too expensive ink, such as high gloss ink, because the greatest advantage of high gloss ink is high gloss of the printing ink layer, but the product will cover the high gloss of the ink layer after dumb film coating, so using high gloss ink for film coating products will cause waste.

　　要注意套印顺序的工艺设计，如在黄底色或红底色上叠印黑色的文字、字母或线条时，应先印刷黑色的文字、字母或线条，然后将黄底色或红底色叠印在其上面，如此既可以体现各个色彩的优势，还可以避免印刷墨层受到摩擦损伤。

　　We should pay attention to the process design of overprint sequence, for example, when printing black text, letters or lines on yellow or red background, black text, letters or lines should be printed first, and then yellow or red background should be printed on them. This can not only reflect the advantages of each color, but also avoid frictional damage to the printing ink layer.
