Not at all likely
I have recently noticed that my EPS files I have been printing containing PMS colors that are blue in nature are printing on the purple-ish side. I have printed out all the test, printhead and color plots and they look perfect. This has happened on both a banner material profile and wet-strength paper profile, both of which 'used' to print normally.
I cannot pin-point where the issue is... profiles, inks, printheads or the Adobe Creative Suite ink management? Below is some of the current information on the inks/printheads in the machine.

Color Correction: checked off
The attached JPEG shows the Pantone 300c chip overlaying the actual print which looks very much like periwinkle.
