Abstract (en)
[origin: EP0479051A2] The invention relates to a method for monitoring copying processes in photographic copying devices, in particular in devices in which a copying unit is combined with a developing unit. The copying process can be started only by reading in job-specific data - for example a job number. These data are then stored together with the copying data and protected against unauthorised access. <IMAGE>
