Black Paper

In the forum sanderpander writes, "I've just designed a business card that's supposed to be printed on black paper. I figure I'd get better results when using screen printing, but I've never designed anything for screen printing before. So what I'm looking for is any advice on what to keep an eye on when designing for black paper and screen printing. And using black paper in general." Metallic ink, thermography, hot stamping, embossing, and printing a black background on white paper or options offered. Share your thoughts, tips, suggestions

And on a somewhat related note, what about printing white ink?
