摘要：
A method for producing coloured, three-dimensionally structured components with free-form areas, having the following steps: provision of a structured surface (10, 140); application of the three-dimensional colour information to the structured surface (10, 140) by means of a non-contacting digital printing process as at least one inking layer (20), wherein ink is applied more strongly, corresponding to the inclination, to inclined surface elements of the three-dimensional structure on at least one of the inking layers than on planar surface elements; drying of the at least one inking layer (20); pulling off the inking layer (20) from the structured surface (10, 140); thermoforming of the remaining at least one inking layer (20); and spraying of a shaping compound behind the thermoformed at least one inking layer (20).

1. A method for producing colored, three-dimensionally structured components with free-form areas, comprising the steps of: - providing a structured surface (10, 140); - applying three-dimensional color information to the structured surface (10, 140) by means of a non-contacting digital printing process as at least one inking layer (20); - solidifying the at least one inking layer (20); - pulling off the inking layer (20) from the structured surface (10, 140); - thermoforming of the remaining at least one inking layer (20); and - back injecting the thermoformed at least one inking layer with a shaping compound; characterized in that ink is applied more strongly, corresponding to the inclination, to inclined surface elements of the three-dimensional structure on at least one of the inking layers than on planar surface elements.
2. The method of claim 1, wherein the structured surface is provided at a film (10), plate, roller (140) or the like.
3. A method for producing colored three-dimensionally structured components with free-form areas, comprising the steps of: - providing a structured thermoformable film (10); - applying the three-dimensional color information, divided into sub-areas, onto the films by means of the non-contacting digital printing process as at least one inking layer (20); - solidifying the at least one inking layer (20) which is not necessarily continuous; - thermoforming the film (10) having the at least one inking layer (20); - back injecting the thermoformed film by a shaping compound, wherein the inking layer faces the compound; and - pulling off the film (10), wherein the at least one inking layer (20) remains on the compound (22).
4. The method of claim 1 or 3, wherein thermoforming is effected by the back injection.
5. The method of claim 1 or 3, wherein the inking layer (20) is made of an elastically curing material or of a material which becomes elastic after curing, for example by heating.
6. The method of claim 3, wherein the inking layer (20) adheres less to the film (10) than to the shaping compound (22) and cohesion of the inking layer is greater than adhesion of the inking layer to the shaping compound.
7. The method of claim 1 or 3, wherein, before applying the inking layer, a further layer is applied to the structured surface (10, 140) or film, respectively, which is at least partially transparent, at least partially semi-transparent or at least partially opaque.
8. The method of claim 7, wherein the further layer is a surface protecting layer, an adhesion-promoting layer or a color priming layer.
9. The method of claim 3, wherein the structured film (10) is exclusively elastically deformed.
10. The method of claim 3, wherein the inking layer (20) is provided with a sealing layer.
11. The method of claim 10, characterized in that the sealing layer comprises a substantially smooth exposed surface.
12. The method of claim 10, characterized in that the sealing layer is dyed in a defined manner in view of color and/or gradation.
13. The method of claim 12, characterized in that color and/or gradation data are adjusted to the data of the three-dimensional structure.
14. The method of claim 10, characterized in that the sealing layer comprises a smaller reflectivity than the underlying inking layer.
15. The method of claim 3, characterized in that the structured film (10) is transparent.
16. The method of claim 3, characterized in that the structured film contacts a mould (52) used for back injection at one location (24) or at a plurality of locations.
