We recommend that black and grey objects such as text and lines are created using pure black.
Example: Cyan 0 %, Magenta 0 %, Yellow 0 %, Black 60 % or Cyan 0 %, Magenta 0 %, Yellow 0 %, Black 100 %)

Deep black 

Regions of black ink can be created by adding in another colour component.

Example: Cyan 60 %, Magenta 40 %, Yellow 20 %, Black 100 %. Depending on your requirements, different ink proportions can be added until the maximum coverage of the product is achieved. This is not recommended for text and lines since slight gaps may occur.
