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.

Abstract: A photographic printer 20 is disclosed for projecting an image carried by a negative to a light sensitive medium 40. The apparatus 20 includes a novel mixing chamber 24, lens carrier 35, and light sensitive web material reel 39, 47. The mixing chamber 24 includes four walls 103a-103d defining a volume and oriented relative to one another wherein the edge of one wall 103 is proximate the face of an adjacent wall 103. This orientation daisy chains around the volume whereby the walls 103 may be moved relative to one another to continuously change the volume so as to correspond to various size negatives and/or masks. The lens stack 35 includes a plurality of concentric shafts 126-131 arranged about a solid shaft 125 with each concentric shaft 126-131 being rotatable separately from the other concentric shafts 126-131. A deck 14-145 is cooperatively attached to each concentric shaft 126-131 with each deck 140-145 having a plurality of lens carriers 55 connected thereto.
