I broke my own "no reduction" rule for this and printed four colours on two different papers. As you can see from the wee film below I cheated somewhat on the second colour by isolating that small background area for printing. I printed a small number on my preferred Zerkall paper, but the two or more layers of ink dries so slowly on these that I printed the rest of the edition on a lightweight tissue (whose names escapes me). This had the great advantage of taking the ink very easily with only a slight rub with a baren - no endless bending over the press :-). I am finishing the prints chine colle-style by bonding them to a heavier weight paper. I like the way the tissue "disappears" and the ink really pops.
