在光盘生产企业的人都知道,印刷质量问题最多,几乎占据了整体光盘质量问题的主体,而且又是非常难于彻底解决。其原因是印刷生产设备还没能形成像光盘复制有在线检验的自动化生产线,与光盘复制相比印刷生产自动化程度不高,没有可靠的在线检测设备,印刷质量更多的依赖于印刷设备的状态、企业的工艺水平和员工的技术水平。而影响光盘印刷工艺的因素包括:菲林制作、绷网、制版、配墨、印制调整、UV固化以及丝网、刮刀、油墨的选择。另外设备印刷压力、速度的调整,环境温度、湿度都是不容忽视的条件。
Everyone at a CD manufacturer knows that print quality is the most problematic, occupies almost the bulk of the overall CD quality problem and is very difficult to solve. The reason is that the printing production equipment has not been able to form an automated production line like the CD-ROM copy-on-line inspection. Compared with the CD duplication, the printing production is not highly automated and there is no reliable on-line testing equipment. The printing quality depends more on the state of the printing equipment , The level of technology and staff’s technical level. Factors that affect the optical disc printing process include: film production, stretching, plate making, with ink, printing adjustment, UV curing and screen, scraper, ink selection. In addition, equipment printing pressure, speed adjustment, ambient temperature, humidity are conditions that can not be ignored.
