Thankyou for your reply. I always shoot in raw and use Lightroom 5 for any post processing. The problem is evident on screen and when I print images. Both my computer (MAC) and camera are set to sRGB. Oddly enough the problem seems to get worse if I set the camera to standard or neutral rather than vivid. I have not as yet calibrated my monitor to my printer as I don't know how to do this, and will need to research it first.
