Re: First print on Al
Yes, I feel got a hold on it with this trial -> I'm very excited about the next ones... (Have to fiddle-a-little with the negative first.) Adulterant: Calcium Carbonate - since it isn't supposed to be there... (At that concentration.) I don't get this bubble thing, I haven't experienced something like that. Are you using the same acrylic ground as Keith? (Liquitex.) Try to decrease gelatin strength + add some rubbing alcohol just before application. Maybe it's too strong and sets before you finish brushing???
