Photopolymer platemaking apparatus comprises a tilting bucket assembly comprising a tilting bucket having a lip, a substantially vertical wall associated with the tilting bucket, and positioning means for maintaining the lip in contact with a substantially vertical wall during tilting of the tilting bucket from an upright position to a pre-pouring position, and for separating the lip from the substantially vertical wall as the tilting bucket tilts from the pre-pouring position to a pouring position. Preferably, the positioning means additionally moves the tilting bucket from the pouring position to the post-pouring position, and from the post-pouring position to the upright position, and maintains the lip in contact with the substantially vertical wall during movement of the tilting bucket from the post-pouring position to the upright position.
