Shift+Edit+Copy Picture+As Shown when Printed+Format Picture

I love to do this because it let's me easily illustrate a financial
concept or scenario to someone without attaching a whole email or cut
and pasting a section of a worksheet that looses its formatting.

The problem I have is that the numbers and letters appear rough and
pixelated to the recipients. Its legible but not as clear as it looks
when I paste it into the body.

Anyone have any ideas to clean this up?
