摘　　要：选用精细制版参数制作CTP版,然后使用进口高档胶印机R700在157g/m2双面铜版纸及300g/m2灰底白卡纸上印刷测控条,通过放大镜观察、仪器测试记录了网点复制过程的变化.从网点变化情况得知CTP版在制作时网点清晰度、锐利度不理想,但可以呈线性输出,而印刷过程中网点扩大偏大,且扩大曲线不够光滑,网点扩大最大处与色别有关.实验过程呈现出的网点复制质量对推动CTP版材的发展及应用提供了研究基础.In this article,we use precise parameters to make the CTP plate.Then print the measure paper on 157g/m^2 duplex coated paper and 300g/m^2 gray background white cardboard paer using exclusive imported offser printer R700.With the help of magnifier and instruments,we can observe and record the changes through the dot copy.From these changes,the conclusion is that the definition and sharpness of dot are not ideal when making the CTP plate.But the dot can be exported linearly.And the spred of dot is greater,the curve isn′t smooth.Also,where the spread of dot is greatst has relationship to color.Showing the quality of dot reproduce,this experiment is benificial to both tht development and application of CTP engraving.
