Abstract: A method for printing on an article can include positioning an article and a fiducial within a field of view of an image sensor. The method can also include generating an image of the article and the fiducial, using the fiducial to determine a print location on the article, and printing a graphic on the article at the print location. A method for printing on an article additionally or alternatively can include transforming a graphic using a shape model to produce a transformed graphic and printing the transformed graphic on the article. A method for printing on an article additionally or alternatively can include retrieving a shape model corresponding to a reference article, obtaining a configuration file corresponding to the article, transforming a graphic based on the shape model and the configuration file to produce a transformed graphic, and printing the transformed graphic on the article.

Abstract: A method for printing on an article can include positioning an article in a print bed of a printing device. The fiducial is disposed in the print bed. The method can also include generating an image of the article and the fiducial, locating the fiducial in the image, using the fiducial to establish a point of reference relative to a print location on the article, providing a raster or vector graphic file comprising a graphic, printing a representation of the graphic on the article at the print location, and removing the article from the print bed.

Abstract: A method of printing a three-dimensional color object having a contoured surface onto a substrate includes printing color ink layers and structural ink layers. A color ink layer is printed onto the substrate. Structural ink layers are printed onto the color ink layer to build the three-dimensional shape of the object. The contoured surface is formed from varying the heights of pixel columns in the printing information. The heights of the pixel columns may be varied by printing different numbers of layers in adjacent columns or by printing the same number of layers in adjacent columns where some pixels in a column have different thicknesses than other pixels in the column.

Abstract: A method for printing on an article can include selecting a shape model. The shape model is generated from a first image and includes a fiducial, a reference location, and a graphic marker, the fiducial is located in the first image. The reference location is based on a location of the fiducial in the first image, and the graphic marker is positioned at a pre-selected location relative to the reference location. The method can also include locating the fiducial in a second image of an article, by a computing device, establishing the reference location in the second image of the article, positioning the graphic marker within the second image of the article at the pre-selected location, and printing a graphic on the article at a graphic location, the graphic location on the article corresponds to the pre-selected location of the graphic marker on the second image of the article.
