    about a year ago i produced a series of etchings  on which i use
blood as an ink. i got pretty good results the process was as follows:
        1. wipe the plate in the normal fashion
        2. paint or drip the blood directly on the plate.(i used
        3. then i placed the plate on the stove which instantly dried
            the blood into a dark redish brown scab type thing.
        4. then printed the whole mess on dampened paper.
    i ran in to a couple of problems with the blood soaking(and
bleeding(no pun)) into areas of the undersired areas of the print
when i didn't heat it on the stove. end resulting color was not the
same as blood, but a great redish brown. when people saw the color
and the texture, they either understood, or were intrigued enough to
ask. most importantly though, after a year the blood, scab mess is
still strongly adhered to the print.
