With that said, we offer some of the best answers to the question of color consistency.
When exporting to a PDF, in the output section, make sure the color conversion is “no color conversion”.

If Illustrator files are part of the design, make sure you place them as .eps instead of .ai. This ensures no color profiles are brought into your (In)Design. I recently spent a lot of time figuring this out when i had similar problems to yours

Do you export to a PDF/X standard?, check your rendering intent and colour profiles match to the original, lastly i would not use a monitor alone to compare files, select an area and measure colour values for comparison. Arthur Lenssen – group production mgr.
