With business cards, you have quite a few options. You could print one side or both, perhaps using the back side for a map showing where your office is located or for more information about your business. You might also choose to put sales staff members' photographs on their cards, to help their business contacts remember who they are. Business cards can be printed on light or heavy card stock, in a color or on white. Cards can be embossed, with lettering impressed in the card, or you can use foil stamp letters or black or one or more colors of ink.
Some inks can produce raised letters.
And, of course, photographs can be full color or black and white. In the letterhead stationery arena, a key factor is paper quality. When choosing a print shop to handle your business cards and stationery, consider whether you'll need design assistance and choose a firm that can provide it if you do. Ask for references and check them, and seek recommendations from other businesses in your community. Quantities run will affect the cost, with large batches costing less per unit, sometimes significantly less.
