## Abstract

An apparatus (300) for printing conductive lines on a substrate includes a printing element (320) for printing a pattern of conductive material (204) on the substrate; and an imaging element (324) configured to sinter a first part of the pattern of conductive material.

## Claims

### Claim 1

An apparatus for printing conductive lines on a substrate comprising:
a printing element for printing a pattern of conductive lines of nano-particles on the substrate;
an imaging element that sinters a first portion of nano-particle lines;
a carriage that transports the printing element and the imaging element relative to the substrate; and
wherein the printing element precedes the imaging element in a direction of travel of the carriage.

### Claim 2 (depends on 1)

The apparatus of claim 1 further comprising:
a third element for removing a second part of the pattern of conductive material.

### Claim 3 (depends on 2)

The apparatus of claim 2 wherein the third element removes the second part of the pattern of conductive material by washing.

### Claim 4 (depends on 2)

The apparatus according to claim 2 wherein the third element is not integrated in the apparatus.

### Claim 5 (depends on 2)

The apparatus according to claim 2 wherein the third element is integrated in the apparatus.

### Claim 6 (depends on 1)

The apparatus of claim 1 wherein the imaging element is a laser.

### Claim 7 (depends on 6)

The apparatus according to claim 6 wherein the laser imaging element sinters lines of variable thickness.

### Claim 8 (depends on 1)

The apparatus of claim 1 wherein the printing element is an inkjet printhead.
