Question about the 4/ designation on business cards?

I am trying to order business cards online and an option that I find repeated a lot is the 4/0, 4/1, 4/2, 4/3, or 4/4 option. I am guessing it means colors but i would really like to make sure and a good explanation of this option would really help. Thanks!

Question about the 4/ designation on business cards?
These numbers signify the colors used on the front/back of your print. 4 = Full Color, 1 = Black, 0 = No Printing. Thus 4/4 means full color printing on the front %26amp; back, 4/1 means full color printing on the front with black printing on the back, and 4/0 means full color printing on the front with no printing on the back, not sure about the other numbers.
Reply:These refer to what's known as 4-color process (also known as CMYK). The 4 colors for printing are cyan, magenta, yellow %26amp; black. (As opposed to 3-color for your computer monitor, which is RGB - red, yellow, green)





The first number is the colors on the first panel (the front of the card) and the second number would be the color on the second panel (the back). If you are only having the front of the card printed, this would be 4/0. If you were to have the front printed %26amp; just black text on the back, it would be 4/1. If both sides were printed in full color, it would be 4/4.
