4 Document Imaging

In the late 1980s, fully addressable imaging devices that no longer used fixed format slides appeared, GB/T 17294.1- In cooperation with manufacturers and users, a new method for controlling the quality of the images produced by these fully addressable image recorders has been developed. These standards describe a digital target that, when called up by software, will generate an image. Since the target can only be generated from digital data, it is independent of the specific computer output microform. (COM) manufacturers. At that time, these devices were mainly used to output enterprise reporting management (ERM) data. The relevant standards developed include. ---GB/T 20494.1-2006; ---GB/T 20494.2-2006. ......
