I don't think you can make a black only in RGB mode. When you print a black color from RGB, there is very likely going to be more than just a little color ink mixed with it. Only in CMYK do you get real black ink all the time. I'm pretty sure that's why you can only use a CMYK or measurement file to create them in ColorshopX. Something of note about ColorshopX, not only is the book useless, but it is built from the ICC tools collection. There's a whole lot of good tools in this collection. I think Colorthink from Chromix is about the same thing, though I haven't used it yet, and it is $50 more than ColorshopX. Also there is a "tutorial" on ColorshopX at Xrite's online tutorial site:http://www.measureitrite.com/catalog/graphic_arts.aspx Not sure if it is any good, haven't gone through it yet. When I get home, I can make some BO profiles. Anyone know how to get upload permission to the files area?
