Abstract

Method and apparatus for creating an individualized decoration on the surface of a three-dimensional object (c). The decoration is stored in electric form. The decoration is projected and developed directly on the surface of the object. According to the individualization process of the present invention, the decoration is formed on the surface of a three-dimensional object of complex shape without the use of solid intermediate materials or mechanical operations.

Claims

1. Method for creating an individual decoration on a non-planar surface area of a three dimensional object (c), characterized in that

the decoration has been stored in an electronic form,

shapes of surface areas of objects to be decorated have been stored in an electronic form,

the object to be decorated is viewed by a user with a graphics program, wherein the graphics program includes one or more elements that are selected by the user and arranged on the non-planar surface area of the electronic form of the object, thereby forming the decoration, and

the decoration is projected directly to the non-planar surface area of the object by exposing the object and developing the decoration.

2. Method as defined in claim 1, characterized in that the non-planar surface area of the object is sprayed with a photo-sensitive emulsion, whereupon the decoration is projected onto the non-planar surface area of the object and developed.

3. Method as defined in claim 1, characterized in that the decoration is projected onto the non-planar surface area of the object directly from the memory of a computer.

4. Method as defined in claim 1, characterized in that the shapes of the surfaces of the objects to be decorated have been stored in an electric form.

5. Method as defined in claim 1, characterized in that, based on the non-planar surface area shapes of the objects, to minimize the distortion of the decoration, one or more image processing filters are used in an automated image processing program, in which the decoration is filtered before being projected onto the non-planar surface area of the three-dimensional object.

6. Method as defined in claim 1, characterized in that, in the method, the object (c) to be decorated is selected from Internet pages or other computer selection facility, and that an image of the object can be viewed with elements of the decoration as they would appear if they were actually arranged on the non-planar surface area (f) of the object.

7. Apparatus for creating an individualized decoration on the surface of a three-dimensional object (c), characterized in that

the apparatus comprises a computer in whose memory the decoration has been stored in an electric form, and

devices for exposure and development, by means of which the decoration is projected and developed directly on the surface of the object.

8. Apparatus as defined in claim 7, characterized in that the computer is provided with browser software, by means of which the object (c) to be decorated is selected from Internet pages or an equivalent selection facility, and graphics software which can be used to view the object and lay out image and other elements on the surface (f) of the object.

9. Apparatus as defined in claim 7, characterized in that the apparatus comprises a lens (m) that is larger than the object to be decorated, causing the projected image to be diminished and focused when it falls on the surface of the object and making it possible to accomplish the decoration of the surfaces of the three-dimensional object by a single exposure.

10. Apparatus as defined in claim 7, characterized in that the apparatus is provided with mirrors for lateral reflection, allowing the entire three-dimensional surface to be exposed at once.

11. Method for creating an individual decoration on a non-planar surface area of a three-dimensional object (c), characterized in that:

the decoration has been stored in an electronic form,

shapes of non-planar surface areas of objects to be decorated have been stored in an electronic form,

the object to be decorated is viewed by a user with an Internet browser-based graphics program, wherein the decoration is determined by the user arranging one or more elements on the non-planar surface area of the electronic form of the object and the elements are ready-made pictures or patterns selected from Internet, and

the decoration is projected directly to the non-planar surface area of the object by exposing the object and developing the decoration.

12. A method for creating an individual decoration on a three-dimensional shaped surface of an object, the method comprising the steps of:

storing the shape of the three-dimensional surface in electronic form,

providing a graphic program that displays the electronic form of the three-dimensional surface and enables a user to define a decoration by arranging one or more elements on the electronic form of the three-dimensional surface,

storing the decoration in an electronic form,

treating the three-dimensional surface with a photo-sensitive substance,

projecting the electronic form of the decoration onto the three-dimensional surface, and

treating the photo-sensitive substance to develop and fix the decoration on the three-dimensional surface.

13. The method of claim 12, further comprising the step of filtering the decoration before the step of projecting the electronic form of the decoration onto the three-dimensional surface in order to minimize distortion.

14. The method of claim 12, wherein the one or more elements are each two-dimensional.

15. The method of claim 12, wherein the graphic program is accessed by the user through an Internet browser.
