Digital BW, The Print

At one time I had a self inking rubber stamp which was made for RC photographic papers.  This stamp was sold as a "micro-poor, dry ink, ink stamp."  I believe it was made in Sweden.

It was a typical self inking rubber stamp, but the ink pad was inked with a liquid black ink that was allowed to dry before its use.  When used, the pigment would transfer to the print, dry.  What was deposited was a like a light coating of carbon which did sick to the RC paper base.

One could smear the ink a bit if they tried, but under normal conditions, it would not transfer if the prints were stacked, or rubbed against each other.  It was the best system I ever had to mark prints.

Sadly, I used up the supply of ink I had on hand and could not find anymore.

The only down side of the ink stamp was the number of prints that could be stamped before re-inking.  Only about a dozen prints.  I had several pads on hand so the ink could be drying while I was using another one.
