My publisher's new printer wants me to reset my CMYK background values to no more than 240% on my latest cover art.  We never had to do that before.  I have no idea how to do that.  HELP?

Unless you have a really good quality of paper to print on a high value CMYK will ink soak the paper. It's not only the extra ink used it's the poor quality it will produce. Higher CMYK values mean more ink used. Here is an example of a 252% color. On top is same color but with a curve layer adjustment bringing it to 229%.

Okay.  Thank you so much!  I did find something in my Color settings last night that allowed me to change ink percentage from 300% to 240% in the CMYK drop down menu in working spaces, and to change to "working CMYK"  that seemed to do the trick for the whole entire cover, but I never thought of using the curves adjustment.  That's what you get when you learn by experimentation.  I've gone through short tutorials, but not "the whole book", per se.  I REALLY need to do that.
