Embodiment Construction

[0122] exist figure 1 The vehicle 1 is shown from the side, which is printed by the system 2 . The system has a base part 3 and a robot arm 4 (articulated arm robot) consisting of a plurality of movable elements and a printing head 5 arranged on the robot arm. The base can be rotatably and movably mounted so that the arm with the print head for printing can be moved to all parts of the vehicle. During printing, this print head is situated at a small distance from the surface of the vehicle and emits ink droplets 6 there which have sufficient momentum to reach the surface. The spacing may be approximately 1 cm.

[0123] The image 7 is printed on the vehicle 1 . The image can have different regions 7a and 7b. The regions can be distinguished, for example, by having different colors. The areas can also be differentiated in that one area is printed gridded (in halftone method) and another area is printed without gridding (in full tone method).

Abstract

The invention relates to a method for printing an object, such as a vehicle or a body of the vehicle, wherein at least one area of ​​the surface of the object (1) is printed, the method having the following method steps: providing an image (7 , 26); three-dimensionally measure (B) at least one region (24); generate the number of spatial points (C) corresponding to the region; generate a three-dimensional grid (C) corresponding to the region; generate Trajectory data of the manipulator (4) of the inkjet printing head (5), i.e. a three-dimensional trajectory; generate grid data (E) for controlling the inkjet printing head (5), i.e. a grid matrix, especially a three-dimensional or Higher dimensional grid matrix; moving the manipulator (4) using trajectory data; and printing (G) images (7, 26) with inkjet print heads (5) using grid data. This method enables the formation of multicolor prints, so-called 3D surfaces with arbitrary images, at will.

Description

technical field [0001] The invention relates to a method for printing objects. Furthermore, the invention relates to a system for printing an object and a method for printing at least one image on an object, in particular a vehicle. Background technique [0002] I) Introduction and prior art [0003] It is known to paint vehicle bodies monochrome or also polychrome. Multicolor painting can be carried out already in production or afterward. It is also known that the bodywork is provided with color graphics. For example, advertisements are placed on the side or rear of the vehicle. Most of these advertisements are first printed on a film, and the film is then transferred to the vehicle body. The larger the film and the more curved surfaces the vehicle body has, the more time-consuming and difficult it is to apply the film. In contrast to this, artistically demanding images are mostly applied manually using the so-called airbrush technique. [0004] DE 37 37 455 A1 discl...
