How do i adjust individual CMYK colours for printing

A printer profile for your printer is either provided by the printer vendor, or some really expensive third-party software solely for that profile building purpose. One can adjust individual CMYK values in third-party applications such as the Affinity, Pixelmator, Adobe, and free GIMP software.

Although one can play with the CMYK slider in Apple's Pages on macOS Sonoma 14.2, the application has a one-track color space focus and still makes things RGB.

Since upgrading to Sonoma i cannot find the sliders.

InDesign is an industry standard—

You might also try Graphic converter https://www.lemkesoft.de/en/image-editing-slideshow-browser-batch-conversion-metadata-and-more-on-your-mac

I have only used it for simple conversions from RGB to CMYK..... so don't actually know if it will do what you need, but it might!

I gave up the big program for lean mean PixelMator Pro
