We have been using the Xitron Sierra 7.1 workflow with good results. However, Sierra is not being developed further, which would block any upgrades on/of our iMacs due to incompatibility issues with the Sierra Client and newer Mac OSs. I've begun looking at Xitron's replacement, the K2, but am also looking at the Fuji XMF software also. We have been using Sierra for impositions and proof output, then exporting to a Fuji XMF Gateway server for plates to our Fuji platesetter. If anyone's used the XMF platform for layout/imposition, how well does it work? and would there be advantages over Xitron's new offering?
