odd colour shift

I have two laptops one on vista and one on XP both have the same photoshop installed, both have the same Epson 2880 printer drivers installed. both have the same profiles installed for printing. I have both of them screen calibrated so with the same image they both look nearly the same, if I print from either one using identical print settings the prints are almost identical, except:--
for blue bells!!!
on one the Epson print preview shows the flowers blue and one the other purple.Yet the rest of the image grass trees etc are almost the same, and this is what gets printed, both have nearly the same tones and hues for the greens, browns etc but not the flowers????
oh and any image with blue sky prints out the same [correctly ] from either laptop!!
why blue bells only ?? it's driving me mad.

I'm going to guess that it's because oif colour space differences and how the colours are displayed on the two monitors.

Bluebells are notorious for being a problem to photograph on film because of the large amount of UV light they reflect. It's not such a problem with digital, but I suspect that there are colours in your image that don't display on the screen but are there when you print.

In other words, the colour gamut of the printer means you are printing colours you cannot see on the laptop.

I'd check that all cameras and Photoshops are set to the same colour space. Maybe you have one on sRGB and one on AdobeRGB?

Bluebells are a nightmare to get sorted
I'm guessing their colour seems to sit right on the edge of the gamut.

Apart from John's comments...

I presume that the bluebell shots appear the same in Photoshop?
If not, then you have a display calibration issue - I'd guess you're using the Huey or Spyder software?? DispcalGui & Argyll give much better control, and allow better 'native' setups that most other calibration software.

If it's just the Epson print preview that's different then do check you have the correct association with the profile set in the Windows display driver (Display Settings / Advanced / Color Management). Probably a good idea to remove any older profiles from there are well and ensure the current profile is set as default (not all colour management tools link this in )

Hope that helps!

well thanks every one for the comments and suggestions, I find that when I print on the image no matter which laptop it comes from the blue bells are a shade of purple rather than blue and it now turns out that the shade of blue on either laptop depends a bit on the software used to view the image.I have also found that images of a Vanda Orchid also with blue/ purple flowers has the same effect, its just that colour hue and i have to live with it.
thanks
