Keep the paper good planeness, attention should be paid to the quality of the source from the baguanhe control: one is to maintain the stability of the paper into the paper do not just immediately put into use, it is best to rotate over time to better use the result; the other is stored on paper warehouse and cutter workshop and business card printing and membership card-making workshop of temperature and humidity, to maintain the equilibrium conditions, cannot be placed within a larger geographical imbalance in order to prevent the occurrence of the deformation.

保持纸张良好的平整度，应注重从质量源头上进行把关控制：一是要保持纸张性能的稳定性，刚进的纸张不要马上投入使用，最好旋转一段时间后使用效果较好；二是存放纸张的仓库和切纸车间与制卡和会员卡制作车间的温、湿度，要保持相应的平衡条件，不能存放在较大的悬殊情况，以防止变形情况的发生。
