(I heard this tip from Rick Glawson a long time ago).
When you get one of those glossy metallic logos, supplied by the customer as "camera art", you know how hard it is to work with. Both scanners and photocopiers have trouble with the gold foil embossing. It usually turns black, and it is usually on a dark background. You can at least get a viewable image by putting a thin piece of vellum between the scanner glass and the artwork before you scan or copy. It will diffuse the shiny part and scan as light gray.
This process might not give you "camera art", but at least something to work from.
When I've had problems with reflective or hard to scan art, I just pull out the digital camera, shoot the image and bring it right into the program.
I was at a seminar in Denver over the weekend and there were 3 people that had their cameras and card readers. Very fast and clean.
