三种热敏CTP制版参数优化分析

Optimization Analysis of Three Kinds of Thermal CTP Plate Making Parameters

针对中国、德国及日本所生产的各具代表性的阳图热敏版版材FIT-C、Thermostar、LH-PA的制版相关参数显影温度、显影时间、毛刷辊转速、激光发光功率进行分析研究,正交试验结果表明,对制版影响的次序为激光发光功率-显影温度-显影时间-毛刷辊转速,由此得到三种版材的最优化的组合方案.比较三种版材制版条件,发现版材LH-PA最环保,或能为企业选择版材提供参考.

According to the plate-making parameters of the positive thermal plate version FIT-C,Thermostar and LH-PA,which are produced by China,Germany and Japan respectively,the development temperature,development time,brush roller speed and laser power are analyzed.The orthogonal test results show that the order of the influence on the platemaking is the laser light power-the development temperature-the developing time-the brush roller speed,and the optimized combination scheme of the three plates is obtained.Compared the three plate making conditions,it is found that the plate LH-PA is the most environmentally friendly,and it may provide a reference for the choice of plate.
