I found this technique on Too Cool Stamping, she has a post here and here on this technique. Angie describes this technique as a combination of Tim Holtz's stamping on texture fades as seen in this video, and the kissing technique.
Choose an embossing folder that has a large blank area in the part that will be de-bossed. On the side of the folder that has the blank area raised, color with a dye ink by rubbing or pressing the pad over the surface. Do not push ink into the other areas.
