Somebody may want to try and comment to us:
This is what I do.
By chance I found that the best way to redo or adjust a pigment it's first
to try it with hot water (as much as possible).
Once you feel that there is no more bleeding and that's it then take the
image to hang and dry.
Do not let it dry completely (give it an hour or so) and get it back with
humidity or damp.
Then put it back on hot water.
It will start melting like butter but be careful of too much.
Try first and then we will talk about why and how.
