影响电分设计制版质量的原因

随着现代印刷制版的发展,越来越多的人们开始关注电分设计制版质量的方法.那么影响电分设计制版质量的原因都有哪些,就由济南书刊杂志印刷给大家讲解一下:
With the development of modern printing, more and more people begin to concern the quality of the design of the plate separation method. Then the impact causes electricity design and plate making quality of all which, by the Ji'nan print books and magazines to explain:
1、显影时间
1, development time
PS版的显影时间主要由PS版的种类、曝光时间及显影液的浓度、显影温度等条件来确定.
PS version of the development time is mainly determined by the type of PS version, exposure time and concentration of the developer, the development of temperature and other conditions
2、显影液浓度
2, developer concentration

在制版中影响印版质量的因素更多,主要有显影液浓度、显影温度和显影时间以及显影液的循环搅拌情况、显影液的疲劳衰退程度等.济南宣传页印刷

The factors that affect the quality of the plate are most in the plate making process, such as the concentration of developer solution, the temperature of development and the time of development, the cyclic stirring of the developer, and the degree of fatigue degradation of the developer
3、显影温度
3, developing temperature
显影温度高时,显影液中分子热运动剧烈,对涂层中树脂的溶解力就大;温度低,分子热运动减弱,对树脂的溶解力差些;所以造成了在相同的曝光条件下,不同温度所需的显影时间也不同.济南彩色设计印刷
Developing at the high temperature, the thermal motion of molecules in intense developer, is on the dissolution of stresses in the coating resin; low temperature, molecular thermal motion decreases, dissolving capacity of resin is less; so caused under the same exposure conditions, developing the different temperature and time required are also different.
4、显影液的循环
4, the development cycle
显影是通过显影液与PS版感光层之间的接触、溶解来完成的,因此多采用动力显影方式.济南精装书制作
The development is done by the contact between the developer and the photosensitive layer of the PS plate, so as to make use of the power development mode
相反采用静显影方式,显影液不能有效流动循环,显影速度则会明显降低,显影均匀性也差.
On the contrary, the developer can not flow effectively, the development speed will be significantly reduced, and the development uniformity is poor
