Abstract
The present invention relates to a gravure printing process for the production of a virtual three-dimensional pattern in a coating comprising flake-form effect pigments on a print substrate, to a coating produced in this way, and to the use thereof.
Claims20
Process for the production of a virtual three-dimensional pattern in a coating on a print substrate, in which
- cells and/or hachures located on a surface of a gravure printing plate
- are filled with printing ink and subsequently
- the printing ink is transferred to a print substrate and solidified, where
- the printing ink comprises flake-form effect pigments and
- a first type of cells and/or hachures which have a flat base and side flanks, where the base is aligned parallel to the surface of the gravure printing plate and the flanks have an inclination angle α in the range from 70° to 90°, relative to the base, and
- a second type of cells and/or hachures which have a flat base and side flanks, where the base has an inclination angle β, relative to an imaginary base line running parallel to the surface of the gravure printing plate, that is smaller than the inclination angle of the flanks of the first type of cells and/or hachures, are arranged on the surface of the gravure printing plate, and
- where the first and second types of cells and/or hachures are arranged alongside one another, at least on a part-area of the surface of the gravure printing plate, with formation of boundary regions.
