Abstract
A device can expose both lithographic printing plates and color proofing materials using the same thermal exposure head. The color proofer mode uses four or more donor sheets and transfers a dye onto a receiver sheet. In order to automate the process, the donor sheets are packaged in a box containing the different donor sheets and receiver sheets in the order they are used by the proofer. The proofer picks up the sheets using a vacuum supply and exposes them.
