Abstract
A device for copying photographic masters onto photographic copy material, the device including a masters stage on which the master is conveyed to a measuring station where it is impacted with light and measured. Subsequently, copying light quantities required for exposure are determined from this measurement. After the measuring station, in the direction of conveyance, there is an exposure station, where the master is impacted with the determined copying light quantities and copied onto copy material. The device further includes a transmission measuring system and a reflection measuring system for measuring test masters or test copies. The transmission measuring system and the reflection measuring system are integrated, structurally speaking, in an area of the masters stage on which the master is conveyed, measured and copied onto the copy material.
