Sometimes simple is best with business cards, it really depends on your company and the brand you are trying to communicate.

Many designers find it tough to design for letterpress because you have to think in terms of individual colors instead of full color with offset/digital printing.
Since each color requires additional passes through the press, most people restrict their choice of colors to between 1 and 3.
