Black card

Hi, I ongoing to develop a product using black as the background on the foil. I using foil as some features of card need to have the foil effect. Unfortunately, I did not the card black color as black that require. My current method print on the foil:

1. Print white base twice to area that we do not need foil effect then,
2. Print CYMK then,
3. Print K to get solid color of black

The foil effect is word “Aisya” and the design back of mydebit and MC logo.

Please kindly advise.
