I second that a good calibrated monitor, printer etc all contribute to a good workflow with repeatable, accurate and predictable color, tonality and ink density etc.
The other aspect to consider to improve matters is a print viewing booth that has consistent viewing so unaffected by different colour temperature of different daylight parameters such as sunny/cloudy/winter/summer ambient lighting etc. Some models are more compact than others and can sometimes be found at reasonable cost used, I have the Just Normlicht and Graphiclite which I found extremely useful when I used to work with design studios and other photographers.
