Abstract: In some examples, a system generates three-dimensional (3D) object data for printing by a 3D printing system, the generating including determining a region in which to generate a wear indicator, and computing an arrangement of spatial shells of variable thickness in the region, where the spatial shells contain data representing at least one property of the wear indicator.

Abstract: In one example in accordance with the present disclosure, a method for assessing print quality is described. According to the method, a printed mark is converted into a digital binary mark. A number of values are calculated for the digital binary mark. The number of values include at least a perimeter length value and a value describing a characteristic of an intensity histogram for the digital binary mark. A combined representation of the number of values for the digital binary mark are compared against a combined representation of a number of values for a model printed mark. When the combined representation for the digital binary mark is greater than a predefined distance away from the combined representation for the model printed mark, an operation of a printing device that generated the printed mark is adjusted.

Abstract: Imaging a package to identify contents associated with the package includes with a camera of a point of sale (POS) system, imaging the package, where an identical identification mark is located on all sides of the package such that when an image of the package is captured, an image of the identification mark appears in the image irrespective of an orientation of the package to the camera and with a database, identifying the contents associated with the package based on the identification mark from the image.

Abstract: In one example of the disclosure, it is determined, based upon a scan of an overt image included within a printed document, that the image includes a subset area with an expected marking agent response. It is determined, based upon the scan, that a feature of the subset area meets an expected quality threshold. It is determined that a data payload represented by features of the subset area matches expected data for the image. A first measurement of the subset area is made, and it is determined that the image was produced by a printing device based upon a comparison of the first measurement to a second measurement of a sample image printed by the device. Authenticity of the printed document is determined based upon the expected marking agent response, the expected quality threshold, the expected data, and the comparison of measurements.
