## Abstract

Forming fabrics for making tissue webs are provided with structural icons on the side of the fabric that does not contact the tissue web during formation. The resulting tissue web has good formation without pinholes, yet contains a watermark corresponding to the shape of the structural icon.

## Claims

### Claim 1

A papermaking forming fabric having a sheet-contacting side and a machine-contacting side, wherein one or more structural icons are positioned on the machine-contacting side of the fabric.

### Claim 2 (depends on 1)

The fabric of claim 1 wherein the structural icons are printed onto the machine-contacting side of the forming fabric.

### Claim 3 (depends on 1)

The fabric of claim 1 wherein the structural icons are silk-screened onto the machine-contacting side of the forming fabric.

### Claim 4 (depends on 1)

The fabric of claim 1 wherein the structural icons are stitched into the machine-contacting side of the forming fabric.

### Claim 5 (depends on 1)

The fabric of claim 1 wherein the structural icons are woven into the machine-contacting side of the forming fabric.

### Claim 6 (depends on 1)

The fabric of claim 1 wherein the structural icons are provided by a decorative fabric layer overlaid onto the machine-contacting side of the forming fabric.

### Claim 7 (depends on 1)

The fabric of claim 1 having a double-layer structure.

### Claim 8 (depends on 1)

The fabric of claim 1 having a triple-layer structure.

### Claim 9 (depends on 1)

The fabric of claim 1 wherein a structural icon comprises a multiplicity of elements.

### Claim 10 (depends on 9)

The fabric of claim 9 wherein the size of the elements is about 2 millimeters or less.

### Claim 11 (depends on 9)

The fabric of claim 9 wherein the spacing of the elements is from about 0.2 to about 2 millimeters.

### Claim 12 (depends on 9)

The fabric of claim 9 wherein the element density is from about 25 to about 500 elements per square centimeter.

### Claim 13 (depends on 9)

The fabric of claim 9 wherein the element size, the element spacing and/or the element density differs with distinct areas of the structural icon.
