Title: Method for making unidirectional graphic article

Abstract: The present invention relates to graphic or informational articles that may be applied to a surface of a translucent or substantially clear substrate so that the image may be viewed through the substrate. The present invention is an indoor advertising system or kit that includes two components. The first component is a substantially clear, perforated imageable film layer with a perforated adhesive layer on a surface thereof. The second component is a non-perforated colorant transfer component that includes a removable carrier film with at least one color layer on a surface thereof. The present invention further includes a process for making the graphic articles. In the process of the present invention, an image layer is formed on a first major surface of a substantially clear, perforated imageable film layer. A colorant transfer component with at least one colored layer comprising a pigment is laminated to the imageable film layer such that the at least one colored layer is adhered to the unperforated areas of the image layer. The colorant adheres to the unperforated land areas of the image layer without significant bridging across the apertures of the image layer.
