Jon, I'm not sure I understand what you are saying. I think you imported the Symbol tiff image of the MC-70 into Xara and inserted it into an Office document and you see them rendered differently on your screen.
I imported the tiff image into Xara Xtreme Pro and opened it in Photoshop 7.0 using the imbedded profile. Here are screen grabs showing them side by side.
