## Abstract

A method of forming a digital print on a surface (2) by applying powder of dry ink (15) including colourants (7) on the surface, bonding a part of the dry ink (15) powder to the surface (2) by a digital heating print head (80) such that the digital print is formed by the bonded dry ink colourants (7) and removing non-bonded dry ink (15) from the surface (2).
