Maybe it's a contrast thing, but it looked too plain on my screen.

Although I found the person that made this, I can say, "I don't know".if it is good/bad or other. I think it would be a good idea to forward the pdf to the outfit that manufactures these displays and ask them, "What do you think?" They would probably have a pretty good feel on what it would *really* look like as a final product and possibly offer a suggestion or two. Likely they've run 100's, if not 1,000's of these things.
