This was an image that was sent to me for separation. Instead of 4 color process, this was broken apart and separated in spot channels through a simulated process. The advantage of this method is having a little more control on the press with the colors. Also the colors are not as translucent, so the image is a little more robust and not so flat.
First, I start off pulling the shares of red out of the image. If there were red graphics involved, I would have added those on a separate plate. This allows the color to be adjusted on the press.
The next shade is yellow. As you add the colors you start to see the way the printing on the press evolves.
The next color is a blue to make up the collar of the subject's shirt.
Then, I ad a cyan for the highlights in the collar and the shades in his blue eyes.
Tho strengthen the flesh, I ad a mauve to bring out the lips and darker shades of the skin tone.
The next color is a based back, translucent black for the shading and tinting of the colors.
A highlight white ads to the dimension of the subject as well as the blending and smoothing of the colors.
Last would be a 25% black to blend in with the shade that completes the image and how it prints on the press!
