After exporting a file to PDF from InDesign to be imposed in Acrobat, we sometimes get unexpected color/appearance changes that are almost always easily solved by printing directly from InDesign. We don't print directly from Acrobat but drag-and-drop the PDF imposition file into the Fiery queue.
The unexpected results seem to happen only with more complex files that use transparency, though it might be something else also. Does anyone know why this kind of thing happens and any workarounds? Are there settings that can be modified in Acrobat to produce better results? The workflow here is PDF-based, so I don't know how to get around these color/appearance change issues that sometimes cause re-prints, etc. because they can sneak by unnoticed, or only show up while printing.
