I know, I know, I haven't made my first print yet but I am also pondering larger prints than my 8" roller transport will accommodate. I am thinking occasional 16x20 or perhaps 20x24. Since it would be used infrequently, I am leaning toward a Unicolor drum or two with the agitator base. It seems to me that the drift-by method of temperature control would be ideal in this application. What I would like to ask is: Will it work?
