Hi, Allen,

The red looks pretty standard red to me.
I'm pretty sure that the graphic itself
(and the underlying PDF file) is fine because
the PDF can be viewed with acrobat, and
the imported graphic looks colorful  at all
the places that it should.  So the problem
happens when the document that hosts the PDF
graphic is printed.
