    摘要： A device for mounting a flexible film which includes a pair of substantially parallel rails having a first plate member disposed near one end with stud elements disposed along the base thereof and projecting substantially parallel to each other. A second plate member is oppositely disposed to the first plate member and is positioned along the rails, with the second plate member having stud elements disposed along the base thereof and projecting substantially parallel to each other. Bar elements are disposed in association with the first and second plate members forming a pivotal clamping arrangement, and a handle element is mounted transverse the rails. A flexible film may be mounted between the first and second plate members by the stud members projecting therethrough.

    摘要： The disclosed invention is for an apparatus and improvements in a method of operating an apparatus for posterior photocuring a photocurable composition. The apparatus includes a housing having an actinic light source therein and near one end is disposed a platform adapted to receive thereon a supported liquid photocurable composition which has been exposed to actinic light through an image bearing transparency and which is selectively insolubilized in the exposed portions thereof. The invention is especially useful for posterior photocuring a selectively exposed lamination in preparing a developable printing plate from a liquid photocurable composition.
