Abstract:
A multilayer sheet assembly with a removable insert for printing by a high speed printer, the multilayer sheet assembly comprising:a base sheet; a face sheet having a predetermined thickness, the face sheet having a window opening and being substantially coextensive with the base sheet, with said base sheet extending continuously over said window; an insert of a different material from the face sheet, the insert having a thickness substantially equal to the predetermined thickness of the face sheet, and substantially filling the window opening of the face sheet; a first adhesive layer having areas free of adhesive, the first adhesive layer discontinuously securing the face sheet to the base sheet, wherein the face sheet and the base sheet have the adhesive free areas to enhance lay-flat properties, said first layer of adhesive being in the form of spots of adhesive, and being spaced slightly back from edges of said sheet assembly; a second adhesive layer removably securing the insert to the base sheet; and the multilayer sheet assembly having a substantially constant thickness of 15 mils or less, and being sufficiently flexible and uniform across its extent to reliably print at a high rate of speed of more than 50 sheets per minute by a printer or copier.
