缩微胶片保存时间长,“可以达到500年以上”~([1]);由于光学一次成型的特征,图像无法修改,“在法律上拥有具有与档案原件同等的效力”~([2]);“数字化文件和缩微品之间的相互转换轻而易举”~([3]),数字化文件易于复制、可通过网络传输、利用方便的优点可以完美地与缩微胶片结合。制作缩微胶片对于保护档案原件,提高档案利用率有重要的意义。缩微胶片的制作,必须通过拍摄、冲洗、拷贝这一系列流程才能完成。在这一流程 Microfilms save a long time, “can reach more than 500 years ” ~ ([1]); due to the characteristics of optical once molding, the image can not be modified, “legally has the same effect as the original file” [2]); “The ease of conversion between digitized documents and microfilm” ~ ([3]). Digitized documents are easy to reproduce and can be transmitted over the Internet, making them ideal for microfilm integration with ease of use. Making microfilms is important for protecting the original archives and increasing the utilization of archives. Microfilm production, must be through shooting, washing, copying this series of processes can be completed. In this process
