Is anyone still printing anything? If you have stopped doing so, might I recommend you start working in the RGB colour space? It could save your business a deal of money.
We don't pretend to know everything about colour. But we do know that what is printed and what is on the screen does not require more than three components. We drop the u-letter to describe that which is fully known.
That is, color=(r,g,b) where each component is a value between (or including) nought and one. In practical terms, these values range between 0 and 255 (with 255 representing 1). Asking even this much variance suggests that one truly believes that paint is obsolete.
