For years we were using the Rampage Rip. It did a very good job of converting RGB to CMYK on the fly within the rip. We have recently updated our rip to a Xitron Navigator Harlequin workflow. I'm finding out that the conversion doesn't come easy to the Xitron. What is the next best workflow. Right now it is using Acrobat analyze and fix prefight to convert to CMYK. Are there any other choices?
