Jelly like surface

Hi, New user of Phenom. I need some direction as to how to stop uncured resin like gel, forming on flat surfaces, when printed horizontal. Would it be a longer cure time, more lift, faster lift etc.
I know I could cure this by changing orientation, but could collect elsewhere then.
Can someone point me in the right direction, for cure time as opposed to lift speed and distance.

share the pictures of the printed model,you can raise the Z axis and add support to reduce the extension of the bottom layer caused by overexposure.
