Thank you for your answer and forgive me if i am not always clear but I am not an english native speaker. In my Photoshop with the ISOCoated v2 300 profile selected as CMYK working space (a CMYK profile recommended by the European Color Initiative with a TAC limited to 300%), when I use a value of 0 for saturation and 96 for brightness, I get a CMYK translation of 5; 3; 4; 0.
For a brightness of 5 (black point), I get 76; 66; 58; 92. (to be continued)
You can use those values as long as the Total Ink limit is not more than 300%. Normally, Cyan is set higher than M, Y, or K because it prints lighter on a press.
The way you choose your white and black points seems very strange for me. I always use HSB values with saturation set to 0 and brightness set respectively to 95 (or 96) and 5. The values are automatically translated to CMYK (using the ICC profile selected in your color preferences). This way, your white and black point values are neutral and consistent with the printing conditions you have chosen.
What method of color correction are you using? The values I gave in the vidoe are ones that are consistent with target values for printing inks on an offset press. Setting values in HSB may not work since it is a different color system that is not based on printable inks. You can use RGB values too, but again these are not printable inks so you can be sure the highlights and shadows will hold on a press.
Correct values for skin tones vary from different races of people, but for caucasians the values for Magenta and Yellow should be close or equal and for Cyan approx. 30% less, unless the skin tone is in a shadow, where cyan will be higher.

why flatten? all adobe products take psds these days

While Adobe CS4 apps allow you to place psd files, its better to flatten them so they are smaller in size and output faster

Hi, would you tell me what the correct values for the skin tone should be? thanks

Also, beginners need to be aware that they need to save their image as a copy. DON'T save over the original image.
Great tutorial, though. Thanks.

Good point stilldescending! Always save a copy or choose duplicate from the Image menu before starting your color corrections.
