摘要
通过耐黄变实验研究了在不同印刷压力下印刷品的白度值随耐黄变时间的变化规律,得到了印刷品白度对耐黄变时间的回归方程,为印刷、包装人员选择包装纸盒材料提供了基本数据.
The experiments about the resistance to ageing mainly tested how the presswork＇s whiteness changed under different printing forces and with the increasing of time. Through the experiment can we get the regression formula of the pressoork＇s whiteness and the time of the resistance to ageing which provided the basic data for people to choose different packaging box.
