CMYK Density

I am preparing a book cover and have converted my cover from sRGB to CMYK color mode after increasing the brightness.

The file creation requirements note that I should use CMYK Values of 60% Cyan / 40% Magenta / 40% Yellow and 100% Black. CMYK total value should not exceed - 240%. Elements should not be bebuilt in 'Registration' (100% of all colors)

Where do I find the setting in Coreldraw X7 to adjust / verify this?

Thanks
