RE: question about silkscreen ink

Crystal, my husband works for Coates which sells screen printing inks and
supplies. He says he has never heard of a ink that does that afterimage but
feels pretty sure that there are several inks with phosphorus in them. The
company's web-site is and there is contact
information on the site for someone near you. You probably need to call or
e-mail someone who works in a lab within the company. I have seen the
afterimage effect you described by using some kind of paper. It took longer
and was much smaller. Good luck! Michelle

flashed on then off. An afterimage of the students shadow remains on the
wall for a few seconds."
