You could try and put a fan on it and see if that will help...
I would say if your going to need a color flow before its going to dry why dont you put it right on the cake and fill it in that way ... With a glaze that you tint...
If you dont have a copy machine you can still do it ... Take your photo that you want and place a piece of wax paper over your photo and out line it in piping gel then turn your piece of wax paper over on to the cake make sure you have it where you want it and then run your hand over the back side of the wax paper to make the outline on to the cake .. Once that is done then your going to out line it in the color glaze or frosting you want it in .. then your going to fill it in like you were making your piece and it will kinda dry on the cake.. Good Luck if there is any way I can help you let me know..
