I'm using my humble iMac to do some fine art prints to watercolor paper. I've calibrated the monitor but it's hard to do accurate color work. I can't afford something like the high-end NEC, so I'm wondering if it's worth getting a second-hand CRT, like a Sony Trinitron. Or what about a second-hand Apple Cinema Display? I've also noticed that the prints I made to watecolor paper look far less saturated than those I've made to ordinary paper on laser printers. Is this variation inevitable?
