Note:

Uncoated paper will dull the color when printed, to see this on your monitor as closely as possible use the uncoated working profile instead of the coated.

Colors in the color mixer with the! in the triangle are outside of typical 4 color offset commercial litho printing capabilities.

Spot colors can provide some of the cautioned colors including fluorescent, metallics and glosses. Most presses will only allow 1 or 2 spots. Spots add to the cost of printing.
