Abstract
A time indicator assembly including a front part and a back part is disclosed that can easily pass through a printer. The time indicator assembly includes a base substrate forming at least part of the back part having a first surface and a second surface extending between edges. A migrating ink is applied over a portion of the first surface of the base substrate, and a release sheet overlies the migrating ink to prevent migration of the migrating ink toward the front part. In one embodiment, an adhesive is applied over the release sheet and onto the base substrate adjacent at least two of the base substrate edges. The adhesive joins a cover substrate forming at least part of the front part to the base substrate over at least a portion of the release sheet and along the at least two of the base substrate edges. Upon removal of the release sheet, the migrating ink migrates through the adhesive to form an image in the cover substrate. In another embodiment a lift strip is formed in at least one of the front part and back part for easily separating the front part and back part to expose and remove the release sheet.
