Printing Issue with Excel 2010

[Amyrlin]

I am creating a document in excel for client use. In the header and footer I have inserted a jpg of a line (to outline the header and footer - strictly for asthetic reasons). However, when I print the document, the text in the document becomes all .. unsharp. Almost like a copy of a copy of a copy. When I remove the jpg of the line, the text sharpens right up.

I have tried the following:
-using the underling/dash key to create a line - this has too many characters and is not allowed

-Inserting a "line shape" into the header and footer - this is not allowed by the system, the shape can only be inserted into the main document.



Any suggestions?
