This is a closeup of a dual exposure plate from my last session. I exposed once with the aquatint screen and then a second time with the Stouffer wedge. In this example, the aquatint is underexposed. You can see this in the region around the numbers which is solid black on the Stouffer wedge. For this area to print black, it will need a more robust dot structure to avoid an open bite. It is interesting that an underexposed aquatint screen can still make fairly dense halftones as you can see on the right. Also, note that the underexposed aquatint has led to an uneven dot pattern on the right.
