Abstract

A method and apparatus for printing on an article are disclosed. An embodiment of a method may include the generation of a virtual mask that can designate areas for printing and/or designate areas to exclude from printing. A method may include utilization of the virtual mask during either 2D or 3D printing such that a print design is printed in areas designated for printing by the virtual mask.

First claim

I claim:

1. A method of partially printing a print design on a surface of an article, the method comprising:
receiving the article on a surface of a print system;
receiving a print design for the article;
forming a digitized image of the article using a sensor system;
identifying one or more first portions of the article and one or more second portions of the article represented in the digitized image based on one or more detectable features on the surface of the article using a computing system, the first portion representing a print area of the article onto which a print material is to be printed and the second portion representing a no-print area of the article onto which the print material is not to be printed;
forming a digital mask representing the second portion of the digitized image of the article and applying the digital mask to the print design to form a modified print design; and
printing the modified print design on the article.

2. The method of claim 1 , wherein applying the digital mask to the print design comprises determining a mapping relationship between the digitized image of the article and the print design and associating the second portion of the article represented in the digitized image with a respective portion of the print design to form the modified print design.

3. The method of claim 2 , wherein the digitized image is represented by a first plurality of pixels and the print design is represented by a second plurality of pixels, and the mapping relationship comprises associating at least some of the first plurality of pixels with at least some of the second plurality of pixels.

4. The method of claim 3 , wherein the first plurality of pixels comprises a first set of pixels associated with the one or more first portions of the article represented in the digital image and a second set of pixels associated with the one or more second portions of the article represented in the digital image, and
wherein the second plurality of pixels comprises a third set of pixels associated with the first set of pixels by the mapping relationship and a fourth set of pixels associated with the second set of pixels by the mapping relationship.

5. The method of claim 1 , wherein the one or more detectable features are identified as the one or more second portions of the article represented in the digital image.

6. The method of claim 5 , wherein the one or more detectable features comprise voids, spaces, or gaps in the surface of the article.

7. The method of claim 5 , wherein the one or more detectable features comprise recesses in the surface of the article.

8. The method of claim 5 , wherein the one or more detectable features comprise surfaces of the article that do not require printing.

9. The method of claim 1 , wherein the sensor system comprises an image capture device.

10. The method of claim 1 , wherein the sensor system comprises a plurality of image capture devices and the digitized image of the article is formed from data from the plurality of image capture devices.

11. The method of claim 10 , wherein the digitized image is formed by synthesizing the data from the plurality of image capture devices through an image registration process.

12. The method of claim 1 , wherein the surface of the print system is a tray that supports the article during digitized image formation and printing.

13. A method of partially printing a print design on a surface of an article, the method comprising:
receiving the article on a surface of a print system;
receiving a print design for the article;
obtaining a digitized image of the article while on the surface of the print system by one or more image capture devices;
identifying one or more detectable features of the article from the digitized image using a computing system;
designating the one or more detectable features as no-print portions of the article represented in the digitized image;
forming a digital mask representing the no-print portions of the digitized image of the article and applying the digital mask to the print design to form a modified print design that excludes the no-print portion from the print design; and
printing the modified print design on the article.

14. The method of claim 13 , wherein applying the digital mask to the print design comprises determining a mapping relationship between the digitized image of the article and the print design and associating the no-print portions of the article represented in the digitized image with a respective portion of the print design to form the modified print design.

15. The method of claim 14 , wherein the digitized image is represented by a first plurality of pixels and the print design is represented by a second plurality of pixels, and the mapping relationship comprises associating at least some of the first plurality of pixels with at least some of the second plurality of pixels.

16. The method of claim 13 , wherein the one or more detectable features comprise voids, spaces, or gaps in the surface of the article.

17. The method of claim 13 , wherein the one or more detectable features comprise recesses in the surface of the article.

18. The method of claim 13 , wherein the one or more detectable features comprise surfaces of the article that do not require printing.

19. The method of claim 13 , wherein the one or more image capture devices comprise a plurality of image capture devices and the digitized image of the article is formed from data from the plurality of image capture devices.

20. The method of claim 19 , wherein the digitized image is formed by synthesizing the data from the plurality of image capture devices through an image registration process.
