This is a mystery - Excel objects that are pasted via link to Word 2013 have kerning issues (the space between letters is inconsistent within words and looks different from the original Excel).
I've tried copying and pasting via embed Excel object and have tried re-pasting as a link. The only thing that fixes this problem is to open the Word doc on a co-worker's computer and re-paste the Excel object link. Just updating the link in Word doesn't help - it needs to be completely copied over again. And it does need to be linked, the Excel figures are being changed every so often.
I have Word 2013, v 15.0.4659.1000, 32 bit. Any ideas?
