Abstract
This invention relates to photosensitized sheet constructions which, upon exposure to an actinic radiation source through a screened image, can accurately reproduce said image. The construction is useful as a color proofing film which can be employed to accurately predict the image quality from a lithographic printing process. This system allows the operator to use either a full layer transfer or an image transfer method of color proofing.
