Abstract
In the method of digitally printing an image onto a substrate, a liquid toner dispersion including toner particles in a substantially non-polar carrier liquid is applied to the substrate as a plurality of droplets and in accordance with a pattern, said pattern being based on the image to be printed. The liquid toner dispersion is thereafter splitted into a first and a second layer, which first layer is rich in toner particles and located adjacent to the first surface, which second layer is rich in carrier liquid. At least part of the second layer is removed by means of a liquid removal device; and the compacted toner particles is fused to obtain the image.

A method of digitally printing an image onto a substrate, comprising:
- applying a liquid toner dispersion comprising toner particles in a substantially non-polar carrier liquid as a plurality of droplets and in accordance with a pattern to a surface of the substrate, said pattern being based on the image to be printed;
- splitting the liquid toner dispersion into a first and a second layer, which first layer is rich in toner particles and located adjacent to the substrate surface, which second layer is rich in carrier liquid;
- removing at least part of the second layer by a liquid removal device;
- and
- fusing the compacted toner particles to obtain the image.
A digital printing apparatus for printing an image on a substrate, comprising:
- an application device configured to apply a liquid toner dispersion comprising toner particles in a substantially non-polar carrier liquid in accordance with a pattern and as a plurality of droplets onto a surface of the substrate, said pattern being based on the image to be printed;
- a splitter device configured to split said liquid toner dispersion into a first and a second layer on the substrate surface, said first layer being rich in toner particles and said second layer being rich in carrier liquid,
- a liquid removal device configured to remove at least part of the second layer, and
- a fusing device configured to fuse the compacted toner particles of the first layer, to obtain the image.
