I want to convert a document containing spot and process colors to CMYK process only. The color swatches palette of a document containing spot and process colors will allow me to delete process colors but the trashcan/delete function are greyed out when I try to delete the Pantone colors.

The default swatches palette does not contain the default CMYK colors. How can I restore the default? Do I have to define each process color or is there a selection of colours somewhere that I can select from?

I am trying to produce a full-color newsletter, hence the need to work in CMYK with a range of process colors.

Where am I going wrong please?
