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.
