The Other Side - Setoff

I picked up this quartet today.







I think I have another of the 1610, but I can't locate it. Have a few others.

Often referred to as offset, but the proper term is set-off.

All too often I see stamps that were stuck together and puled apart leaving ink and traces of paper on the back offered as set-off.

Notice too that the multi-color Americana stamps just involved one color.




That is also when multiple colors show up (not counting the stamps printed in several colors simultaneously).

The other false set-off occurs when a modern dull (aka dry) gum is placed on top of an intaglio (engraved) stamp and put under pressure (and perhaps some vibration too). I don't know if the intaglio ink never completely dries is if it reacts with the gum, but one way or the other there is ink transfer. Drives me nuts when turn over a blue stamp and see red ink on the back. There is one eBay seller I quit buying from because he insisted on throwing everything in one glassine producing ink transfer.

An age old argument. There really is no proper term. Me, I'm an offset guy.
