Do note that the simulate color option gets one closer to what will be printed, but the fact is that one is still looking at a back-lit monitor and the colors on-screen may or may not be even close to accurate.

If you continue doing work for print, I heartily recommend picking up some color swatch books, on printed to uncoated stock and one printed to coated stock. These swatch books are a far more accurate means of judging what CMYK color looks like when printed.

Take care, Mike
