The appearance of corrugated box is uneven, the appearance of paperboard appears concave convex phenomenon, the paperboard is not easy to print, the printing pressure is high, the paperboard will appear pits. When the printing pressure is too low, printing exposure will occur frequently. Generally speaking, the produced paperboard is uneven. If no relevant problems are found in the printing process, and targeted treatment is carried out, this kind of paperboard will not be printed, resulting in waste. So how do we deal with this problem?

　　壓力:壓力控制尤其重要

　　Pressure: pressure control is particularly important印刷壓力不能太輕:在印刷凹凸板時壓力控制非常重要。，印版壓力不宜過輕，在增加印版壓力的同時應把印版調更輕。所以在轉移油墨時，印版不易變形，而且油墨不會附著在印版的邊緣，如果印刷壓力較高，字體就會清晰。

　　Printing pressure cannot be too light: pressure control is very important when printing concave convex plates. First of all, the plate pressure should not be too light, while increasing the plate pressure, the plate should be adjusted to the lightest. Therefore, when transferring ink, the plate is not easy to deform, and the ink will not adhere to the edge of the plate. If the printing pressure is high, the font will be clear.

　　送紙輪壓力不能增大:送紙輪不能壓碎紙板，因此送紙輪間隙調節應控制在-0.4mm紙板厚度。如果太重，紙板就會坍塌，這會導致印刷壓力增加。因此，有必要控制好來料。如果印版壓力也大，印刷壓力也大，就會出現印刷糊、字跡不清等現象。

　　The pressure of the paper feeding wheel shall not be increased: the paper feeding wheel shall not crush the cardboard, so the gap adjustment of the paper feeding wheel shall be controlled within -0.4mm cardboard thickness. If it is too heavy, the cardboard will collapse, which will cause the printing pressure to increase. Therefore, it is necessary to control the incoming materials. If the plate pressure is also large, the printing pressure is also large, there will be printing paste, illegible handwriting and other phenomena.

　　油墨:墨水較好泡在紙里

　　Ink: ink is better in paper

　　紙板的形成會出現凹凸現象，因為紙張的外表受力不均勻，當紙板受拉時，油墨會吸收。因此，為了處理紙張問題，昆山紙盒有必要提高油墨的色含量，降低油墨的粘度，減少油墨的用量。然后，在油墨中加入一種滲透劑，提高油墨的滲透能力，使油墨更好地滲透到紙張上，然后就可以處理這個問題了。

　　The formation of paperboard will appear concave convex phenomenon, because the external force of paper is uneven, when the paperboard is under tension, the ink will be absorbed. Therefore, in order to deal with paper problems, Kunshan paper box is necessary to improve the color content of ink, reduce the viscosity of ink, reduce the amount of ink. Then, a kind of penetrant is added to the ink to improve the permeability of the ink, so that the ink can penetrate into the paper better, and then this problem can be solved.
