## Abstract

An embossing apparatus includes an embossing die that includes a printed relief pattern made up of multiple layers of a deposited material. A resilient surface presses media against the embossing die such that embossed features corresponding to the embossing die are formed in the media. A method for embossing media includes forming an embossing die by depositing multiple layers of ink on a impression layer to form a relief pattern and pressing media against the embossing die to transfer the relief image to the media.

## Claims

### Claim 1

An embossing apparatus comprising:
an embossing die made up of a printed relief pattern made up of multiple layers of a deposited material;
a first cylinder having a resilient surface to deposit an ink image onto a media, the resilient surface for pressing the media against the embossing die such that embossed features corresponding to the printed relief pattern on the embossing die are formed in the media; and
an impression layer in a printer comprising a printed alignment image, the embossing die to be aligned with the alignment image on the impression layer of the printer.

### Claim 2 (depends on 1)

The apparatus of claim 1, in which the printer comprises one of: an LEP printer and a xerographic printer.

### Claim 3 (depends on 1)

The apparatus of claim 1, further comprising the printed relief pattern of multiple layers of deposited material.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the deposited material comprises multiple layers of ink.

### Claim 5 (depends on 4)

The apparatus of claim 4, in which the multiple layers of ink comprise different inks.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein a first layer of deposited material is an adhesive material.

### Claim 7 (depends on 1)

The apparatus of claim 1, further comprising an offline printer to generate the embossing die.

### Claim 8

A printing system for simultaneous printing and embossing media comprising:
a first cylinder;
an embossing die on the first cylinder, the embossing die made up of a printed relief pattern;
an impression layer in a printer comprising a printed alignment image;
a second cylinder forming a nip with the first cylinder such that media passing through the nip is pressed against the embossing die; and
a photo-imaging cylinder to deposit an ink image on the second cylinder, the second cylinder being configured to transfer the ink image to the media as the media passes through the nip.

### Claim 9 (depends on 8)

The system of claim 8, further comprising a printhead to deposit multiple layers of material to form the printed relief pattern on the embossing die.

### Claim 10 (depends on 8)

The system of claim 8, further comprising the printed relief pattern, the printed relief pattern comprising multiple layers of ink.

### Claim 11 (depends on 10)

The system of claim 10, in which the multiple layers of ink comprise different types of ink.

### Claim 12 (depends on 8)

The system of claim 8, wherein the photo-imaging cylinder is part of a printing device that comprises one of: a Liquid Electro Photographic (LEP) printer and a xerographic printer.

### Claim 13 (depends on 8)

The system of claim 8, wherein the impression layer is wrapped around the first cylinder.

### Claim 14 (depends on 8)

The system of claim 8, further comprising a resilient surface on the second cylinder for pressing media against the embossing die.

### Claim 15 (depends on 8)

The printing system of claim 8, further comprising an offline printer to generate the embossing die.

### Claim 16

An embossing apparatus comprising:
an embossing die made up of a printed relief pattern made up of multiple stacked layers of a deposited material;
a first cylinder having a resilient surface to press a print medium against the embossing die such that embossed features corresponding to the printed relief pattern on the embossing die are formed in the print medium; and
an impression layer in a printer comprising a printed alignment image with the embossing die.

### Claim 17 (depends on 16)

The apparatus of claim 16, further comprising a printer to deposit the multiple layers of deposited material of the printed relief pattern.

### Claim 18 (depends on 16)

The apparatus of claim 16, wherein the impression layer is wrapped around the first cylinder.
