Is there any information how long visible prints in blood will remain visible once processed with water-based Amido Black?
Will there be any biological deteriation?
The surface is a steele door that was removed from the crime scene and processed in a controlled environment.
Of course, everything was photographed promptly, both overall view and one-to-one.
I was curious if the visible ridge detail that appeared will remain in tact for several months in the event it has to be brought into the courtroom.
Thanks.
