Any suggestions on how to "onion skinning"?

Ken,

Have you tried snapshoting the card, then somewhere off screen you put
a gray image on top of the snapshot with some blend and take another
shot. Depending on ink combinations you might have a nice result.

Another way, which I don't know how fast it is, is to read each pixel
in the snapshot and convert it using some proportional gray value.
