I created an company-wide email signature template on my MAC starting with an RGB vector logo from Illustrator--converted to a PNG. When some users send an email with the signature template, the logo image looks faded (as if its a watermark) and blurry. This is not consistent with all users, since some signatures appear to be ok. Now, some of the logos placed into a Word document on the PC are faded. When the document is opened on a Mac, the logos usually look fine. --So far the Word documents prints ok, printing isn't an issue with the emails.
