| 无粉腐蚀机 & 烤版机 无粉腐蚀机是凸印、烫金铜锌版印前制版设备，原理是通过腐蚀液物理冲击和化学腐蚀使铜锌版面不耐腐蚀的空白处被腐蚀掉，剩下部分为凸印文字图案。烤版机是翻版和制版时涂布感光层的设备。由外壳、版架、转速控制器以及电热、排水和通风等组成。外壳是金属密封的，版材固定在版架上，由电动机带动旋转，使版面上的感光液流布均匀，并由电热与通风设备使感光液快速烤干。是地图制版印刷程序中的重要设备之一。胶印PS版烤版机（俗称PS版烤箱、烤版箱）是一种传统的胶印制版设备，使用PS版烤版机对胶印PS版进行高温烤版，能使PS版感光图案固化，具有耐磨损、抗腐蚀性能，从而大幅度地提高PS版的使用寿命，使用PS版烤版机烤版工艺在文具印刷、书刊印刷等印刷行业已经普遍应用。欢迎在此交流讨论无粉腐蚀机 & 烤版机操作技巧与维护检修及故障分析、排除方法。 |
