I realize this is counter-cultural on this forum, but knowing how your equipment and materials interact without relying on techno-fixes, might just make you more aware of what's really going on.
As I have said elsewhere, obsessing on colour matching is helpful if you are in product photography that demands exact colour reproduction. But for many photographers, especially the casual printers, but also those who print regularly and sell, it's good to be close and true to what you want as a photographer but over-obsessing on colour matching can be a waste of time when your client hangs your photo in their home or office with completely different lighting and wall colours.
