Where’s the color?

Even when applied lightly, color has the power to transform an image. The conventional halftone image (top bottle), is a pale shadow of the four-color process quadtone (bottom bottle). Printing black and white in four colors can dramatically expand the tonal range of the image–and help you nail the presentation.

A neutral quadtone was created by copying the original grayscale image into each of the four channels of a blank CMYK image. (Note that the full range was copied into each channel and not pasted into the CMYK layer, which would result in a conventional separation.). Then the original grayscale scan was placed in the black channel only of a layer above the others. A layer mask was used to open up the image of the upright bottle only, so this would print in black alone.
