Below are guidelines for working in CMYK mode and adjusting the colours as required in InDesign.
1. CMYK colour mode
It is best to compose your design in CMYK mode – but if you haven't done this, you will need to convert the colour mode before adjusting the colour values:
Select File > Document Setup
Ensure that "Intent" is set to "Print" and confirm.
2. Adjusting colour values
You can adjust the colour values directly in the swatches pallet or colour selector.
