It was found that print through(PT)increased with the amount of ink on paper.
对几种实验室抄造的新闻纸及商业用胶印新闻纸的研究表明，透印值（ＰＴ）随纸面油墨量的增加而增加，而且在实际印刷密度范围内，这种增加是由于油墨颜料和介质渗透所致。
The cause of print through was analyzed and the controlling measure was proposed.
分析了印刷透印产生的原因,并提出了具体的控制措施。
The light scattering coefficient and opacity of the paper are higher in a certain range of beating degree, and the print-through is lower.
其成纸白度随打浆提高逐渐下降，成纸光吸收系数随打浆度提高几乎没有什么变化，而其成纸光激系数、印刷不透明度随打浆度的变化存在一个极大值，透印值随打浆度的变化存一个极小值。
