Overprinting with InDesign

Knockouts, overprinting, trapping and Adobe InDesign.

Recently, a client asked me to redesign a catalog cover using some pretty fancy printing processes. The layout and design was nothing new but I needed to be able to print a photo on the cover which did not knock-out the metallic ink fill behind the greyscale photo. I found this video which does a nice job explaining how to tweak InDesign trapping settings to do this.
