Digital BW, The Print

When you play on let say the Red channel, you play only on it, whilst if you play on M you change C and Y as well and it is virtually impossible to control. K is there because C+Y+M is not printed as deep black by our technical devices, so we help it in adding K. Read a little bit on color theory, you'll get it all.
Printing Color or Quadetones makes no difference, when you change one you change the other two.

  Subject: Re: [Digital BW] RGB vs. CMYK for curves



  but if i'm actually printing with gray inks, or cool/warm grays, not 
  color inks,  what good does having equal values of R.G.B do me? it 
  doesn't mean my print will be neutral, only my photo in photoshop.

  does that make sense? after aplying an RGB curve to get the (gray) 
  inks to "print" properly, the image is such a rainbow, the R=G=B -> 
  neutral grey doesn't apply.

  or is there something i'm missing in you previous post?
  maybe i'm unsure of what you mean.
