## Abstract

A method of forming a textured effect on a substrate, the method comprising steps of: (a) creating a data file of an image having a thickness to be formed as the textured effect on the substrate, the data file comprising print image(s) and a number of times specified for printing of the print image(s); (b) preparing the data file for surface deposition by a printer; (c) providing the substrate on the printer; (d) the printer printing the print image(s) in the data file on the substrate using a layer of clear ink; (e) the printer UV curing the layer of ink; (f) repeating steps (d) and (e) for every print image of the print image(s) for the number of times specified in the data file such that the image formed as the textured effect on the substrate comprises a plurality of layers of printed and UV cured clear ink.

## Claims

### Claim 1

A method of forming a textured effect on a sheet of glass, the method comprising the steps of:
a) creating a data file of an image to be formed as the textured effect on the sheet of glass, the data file comprising at least one print image and a number of times specified for printing of the at least one print image;
b) preparing the data file for surface deposition by a printer;
c) providing the sheet of glass on the printer;
d) printing, with the printer, the at least one print image in the data file on the sheet of glass using a clear ink to form a layer of ink;
e) UV curing, with the printer, the layer of ink;
f) repeating steps (d) and (e) for every print image of the at least one print image for the number of times specified in the data file so that the image formed as the textured effect on the sheet of glass comprises a plurality of layers of printed and UV cured clear ink.

### Claim 2 (depends on 1)

The method of claim 1, wherein creating the data file comprises high resolution 3D scanning of an existing image to obtain the at least one print image.

### Claim 3 (depends on 1)

The method of claim 1, wherein creating the data file comprises an artist creating the at least one print image.

### Claim 4 (depends on 1)

The method of claim 1, wherein ink density of the clear ink results in the layer of ink in step (d) having a thickness of at least 0.05 mm.

### Claim 5 (depends on 1)

The method of claim 1, further comprising printing a coloured image on the sheet of glass.

### Claim 6 (depends on 5)

The method of claim 5, wherein printing the coloured image is performed before step (d).

### Claim 7 (depends on 5)

The method of claim 5, wherein the coloured image comprises at least two portions and printing the coloured image comprises:
printing a first of the at least two portions after printing and UV curing a first layer of clear ink; and
printing a second of the at least two portions after printing and UV curing a second layer of clear ink.

### Claim 8 (depends on 1)

The method of claim 1, wherein the at least one print image comprises a plurality of distinct print images corresponding to layers of the image at distinct intervals of displacement along a thickness of the image.

### Claim 9 (depends on 1)

The method of claim 1, further comprising providing a decorative addition on the sheet of glass and printing over the decorative addition with the clear ink such that the decorative addition is encapsulated within the plurality of layers of printed and UV cured clear ink.
