Abstract: An on-demand stencil for marking or etching metal. The stencil comprises a porous medium having a thread count between 150 to 600 threads per inch and a maximum pore size of 0.003 inches. A non-conductive coating material forms a negative image on the porous medium. Etching solution passes through the porous material to an object. Electricity is applied and a positive image is formed on the object. The stencil is formed by obtaining a porous material with a liner on one side and printing on the other side with non-conductive ink to form a negative image.

Abstract: A multi-layer label/tag is disclosed, which may be utilized either as a label or a tag, depending on the needs of the user. The label/tag includes a printed or printable top face sheet and a number of release layers. The top face sheet is attached to the release layers such that it may be removed as a tag or as a label. Cutting through the multi-layer assembly allows a user to remove the item as a label or a tag, as needed.
