## Abstract

A lightweight, magnetic sign assembly containing a magnetic sign. The magnetic sign contains a flexible substrate. Magnetic ink is bonded to either the top or bottom surface of the substrate, and ink is deposited over the top surface of the flexible substrate. Graphic images are presented by the top ink layer. The sign is lightweight, weighing less than about 6 ounces per square foot.

## Claims

### Claim 1

A lightweight, magnetic sign assembly comprising a magnetic sign which is comprised of a flexible substrate with a top surface and a bottom surface, magnetic ink integrally bonded to a portion of either or both of said top surface and said bottom surface of said substrate, and a layer of ink disposed over said top surface of said flexible substrate, wherein:
(a) from about 1 to about 10 graphic images are displayed by said layer of ink,
(b) said magnetic sign weighs less than about 6 ounces per square foot of surface area of said sign,
(c) said flexible substrate has a thickness of from about 0.01 to about 0.125 inches,
(d) said magnetic ink has a thickness of less than about 0.005 inches, and
(e) said sign has a thickness of less than about 0.03 inches.

### Claim 2 (depends on 1)

The magnetic sign assembly as recited in claim 1, wherein said magnetic ink is bonded to said bottom surface of said substrate.

### Claim 3 (depends on 2)

The magnetic sign assembly as recited in claim 2, wherein said layer of ink is disposed over and bonded to said top surface of said substrate.

### Claim 4 (depends on 3)

The magnetic sign assembly as recited in claim 3, wherein said magnetic ink is bonded to the entire bottom surface of said substrate.

### Claim 5 (depends on 3)

The magnetic sign assembly as recited in claim 3, wherein said magnetic ink is bonded to a portion of said bottom surface of said substrate.

### Claim 6 (depends on 5)

The magnetic sign assembly as recited in claim 5, wherein said magnetic ink is disposed near the perimeter of said bottom surface of said substrate.

### Claim 7 (depends on 6)

The magnetic sign assembly as recited in claim 6, wherein said magnetic ink forms a border disposed near the perimeter of said bottom surface of said substrate.

### Claim 8 (depends on 2)

The magnetic sign assembly as recited in claim 2, further comprising a magnetic extrusion magnetically attached to said magnetic ink.

### Claim 9 (depends on 8)

The magnetic sign assembly as recited in claim 8, wherein said magnetic extrusion is connected to a frame.

### Claim 10 (depends on 8)

The magnetic sign assembly as recited in claim 8, wherein said magnetic extrusion is connected to a linear surface.

### Claim 11 (depends on 8)

The magnetic sign assembly as recited in claim 8, wherein said magnetic extrusion is adhesively connected to a linear surface.

### Claim 12 (depends on 8)

The magnetic sign assembly as recited in claim 8, wherein said magnetic extrusion is an integral assembly comprising a multiplicity of horizontally-extending walls.

### Claim 13 (depends on 12)

The sign assembly as recited in claim 12, wherein said magnetic extrusion is comprised of a multiplicity of receptacles adapted to receive said magnetic sign.

### Claim 14 (depends on 1)

The magnetic sign assembly as recited in claim 1, wherein said magnetic ink is bonded to said top surface of said flexible substrate.

### Claim 15 (depends on 14)

The magnetic sign assembly as recited in claim 14, wherein said layer of ink is bonded to said magnetic ink.

### Claim 16 (depends on 15)

The magnetic sign assembly as recited in claim 15, wherein adhesive is bonded to said bottom layer of said flexible substrate.

### Claim 17 (depends on 16)

The magnetic sign assembly as recited in claim 16, wherein paper is removably bonded to said adhesive.
