Print Problem - bluish tint in otherwise white t-shirts

[Ollokot]

I'v just finished enhancing a group photograph from the early seventies for a friend,there is a fair amount of colour contrast in it,and all looked fine on screen.The colours printed good bar four shall we say brilliant white shirts which appeared from the printer with a sky blue tint. I never had this problem before and can't understand why all the other colours printed fine, even less brilliant white.
The editing software is Adobe Photoshop Elements 7,the printer is a canon pixma MP620 and canon Photo Paper Pro 11.
I would be most grateful for any suggestions,
Best Wishes

Hi Pat,

Can you post the problem image here?

Hi Colin,

Thank you for your reply,in the interim I appear to have resolved the problem which was more of an oversight on my part.
I opened the jPEG image in ACR to see if I could improve it some more and on returning to the editor never noticed it had opened as 16 Bit. I changed to 8 Bit and printed a part of the image that had earlier printed bluish and it came out fine.
I presume it was the printer changing the image to 8 Bit that caused the tint.

Thanks again
Best Wishes

Pat
