ABSTRACT:
A platen 23, 96 having a series of channels 174 which are in fluid communication with a vacuum and a fluid source. The grooves 174 preferably extend through an end of the platen 23 to the atmosphere such that the vacuum has a maximum value. The platen 23, 96 is used in a printer-processor 10 which has a printing unit 11 and a processing unit 12. A light source 18 directs light 64 toward light-sensitive photographic printing material 22 held by the platen 23, 96. A transport system 132 conveys the print material 22 from the platen 23, 96 to the entrance 29 of the processor 12.
