Method for printing surfaces of three-dimensional objects and three-dimensional objects having print
First Claim
1. A method for printing a print of a print image on a surface of a three-dimensional object with a cylindrical or curved surface by inkjet print heads, the method comprising:
- printing a base color layer onto the three-dimensional object; and
thenprinting an upper color layer above the base color layer, wherein the base color layer is printed smaller than the upper color layer, the dimensions of the base color layer being less than the dimensions of the upper color layer in all directions on the surface of the three-dimensional object such that the upper color layer securely covers a margin of the lower base color layer and forms a visible part of the print image outside of the margin of the lower base color layer, the upper color layer representing the print image and being a reference for a size of the print,wherein the base color layer with regard to print resolution indicated in pixels is smaller than the upper color layer by an amount in a range from 5 to 30 pixels.

Abstract
A method for printing on surfaces of three-dimensional objects with a cylindrical or curved surface by means of inkjet print heads includes printing a base color layer onto the three-dimensional object. Then, an upper color layer is printed above the base color layer. The base color layer is printed smaller than the upper color layer. The dimensions of the base color layer are less than the dimensions of the upper color layer in all directions on the surface of the three-dimensional object such that the upper color layer securely covers a margin of the lower base color layer.

- 10. A container with three-dimensional cylindrical or curved surface contours, with a print on a surface of the container, the print being of a print image obtained in a digital print process by inkjet print heads in several printing steps, wherein layers created in consecutive printing steps are subsequently broader going upwards so that each subsequent layer covers margins of the layer below it, and wherein an upper color layer, which is increased with reference to a base color layer below the upper color layer, represents the print image and is a reference for a size of the print, the upper color layer forming a visible part of the print image outside of the margin of the base color layer, wherein the base color layer with regard to print resolution indicated in pixels is smaller than the upper color layer by an amount in a range from 5 to 30 pixels.
