A data medium having a printed image is created by the intaglio printing process. The printed image has at least one first ink area with a first ink layer thickness and at least one second ink area with a second ink layer thickness adjacent to the first ink area, such that the ink layer thicknesses are different. The first and second ink areas are separated by a sharp border line invisible on examination with the naked eye, and the ink layer thickness of both ink areas passes through a minimum in the region of the border line.

Gravure process for printing adjacent color surfaces with various color coating thicknesses

The invention concerns a data medium with a printed image created by the intaglio printing process. The printed image has at least one first ink area with a first ink layer thickness and at least one second ink area with a second ink layer thickness adjacent to the first ink area, such that the ink layer thicknesses are different. The first and second ink areas are separated by a sharp border line invisible on examination with the naked eye, and the ink layer thickness of both ink areas passes through a minimum in the region of the border line.
