Yep, Foxy, I was afraid that might happen. You see, I've been noticing as I format the calendars, when I pick a color for the titles I usually try to pick it somewhere off the pinup. But often times Photoshop will warn me that the color I am picking is "out of gamut for printing." What this means is that color is not able to be replicated by any printing process. Many, many of the digitally done pinups had colors out of gamut for printing. So they are not going to look just like they appear on a computer screen, which after all is glowing, backlit color that can't be replicated by printing, which is a reflective media.
Not being a digital artist I am not sure, but I would think that professional artists creating art digitally would always check to make sure their palette is in gamut if they are creating something that will be printed.
