Abstract
The invention relates to an inkless printing method. The invention also relates to an inkless printing device, in particular configured to perform at least a part of the method according to the invention. The invention furthermore relates to a substrate provided with at least one printed marking realised by applying the method according to the invention and/or the device according to the invention.
Claims38
An inkless printing method, comprising:
- A) providing at least one carbonizable substrate,
- B) determining at least one carbonization related characteristic of said carbonizable substrate,
- C) defining at least one printing zone of the substrate,
- D) position-selectively carbonizing said at least one defined printing zone of the substrate by at least one time position-selectively irradiating of said printing zone of the substrate, by using at least one primary irradiation source to form at least one printed marking within said defined printing zone, and
- E) at least one time irradiating of at least a part of said at least one defined printing zone, by using at least one secondary irradiation source, such that each printing zone is irradiated at least twice during the execution of D) and E).
