Top layer is white. This is the layer that your image will be transferred onto. Second Layer is not bound and is purple. Typically this layer is thrown away. Third Layer is the Carbon (black/blue paper). By pressing on this layer the black/blue coating is transferred to the upper sheet. Fourth bottom sheet is yellow and holds the original in place when using a stencil copy machine.
