Better Grayscale Photos in CMYK
When printed in a CMYK publication, grayscale photos look much better if you create the gray from all four CMYK inks. The result has a much wider tonal range than a simple grayscale image, because it has all four inks to make halftone dots. The easiest way to get a successful quadtone is to use Adobe’s presets in Photoshop.
In Photoshop, choose Mode> Duotone. Then choose Quadtone and click the Load button. Navigate to the Photoshop application folder, and within it: Presets/Duotone/Quadtone/Process Quadtones. Then choose among the presets: CMYK cool, very cool, neutral, wm, very wm, or ext wm.
