凹版印刷网点增大值的研究

Research on Dot Gain in Gravure Printing

主要研究了凹版印刷采用刮墨刀与印版滚筒相同和相反方向以及不同印版滚筒速度对网点增大值的影响。实验发现,刮墨刀与印版滚筒相同和相反方向对网点增大值基本没有影响;印版滚筒速度时网点增大值有一定的影响。

The influence of different direction between plate cylinder and doctor blade, and different plate cylinder speed on dot gain in gravure printing was discussed. It was found that different direction between plate cylinder and doctor blade had little effect on dot gain and the speed of plate cylinder had certain effect on dot gain.
