what I mean by gold and silver is like the foil shiny colours you get on some cards.
I am not sure what kind of printer your using
but for example a standard home pritner would use a colour cart and a black one.
Mine at home uses 5 carts (2 tones of blue yellow red and 1 black).
You can go up to 10 cart the 5 extra are like silver, gold, clear shine coat finish (to smooth out printing bumps) and something else that I forgot
