In MS Office 2016 (Win 10) I have an image that's a 600 DPI scan of my boss's signature, saved as a JPG. The JPG is 3400px wide, so I'm guessing some compression occurs when it's being inserted - I don't know for sure. At any rate, it prints nice and clean in Word v14, but its ugly in version 16.

Is there a better way of doing this? I've tried a PNG, with no improvement.

Higher resolution? Using an image inside a container of some sort? Switching off the
picture editing in Word (if that's possible?)

Just wondering!
