制版照相机 制版照相机是将原稿拍摄成制版用的底片的光学机械。由底架(或吊架)、镜箱、原稿架及光源等部件组成。镜箱的前端是镜头板,上面装有镜头。后部是装感光片的暗盒或吸气板。在暗盒或吸气板上有安装玻璃网屏的网屏架及对光用的毛玻璃。镜箱的前、后端用可伸缩的皮腔连接。常用的光源是在支架上装有反光罩的卤素灯或氙灯。有的还附有拍摄透射稿的透射专用光源。摇动照相机后部的两根螺旋杆,可以分别使原稿架及镜箱前端的镜头板沿着装在底架(或吊架)上的两条平行滑轨前后移动。镜头的焦距、原稿与镜头的距离、镜头与感光片的距离决定在感光片上的图像尺寸与原稿相比的缩放倍率。新型的制版照相机采用微处理机控制,具有计算曝光时间自动曝光、自动对焦、自动换镜头等多种功能。有的机身后部与显影机相连接,曝光后,感光片自动进入显影机,显影、定影、烘干后,送出底片。由于电子分色机的发展十分迅速,制版照相机在照相分色上的用途大部分被电子分色机替代。但在印刷行业中,制版照相机的用途仍然十分广阔,例如拍摄单******片、说明文字及线条图案等。不过,除大幅面的地图外,都不需要大幅面的制版照相机。因而,制版照相机正在向小型化、全自动化方向发展。 欢迎在此交流讨论制版照相机操作经验与维护检修及故障分析、排除方法。
