Abstract: A method comprises providing to a processor or generating by the processor, an image, and a machine readable graphic code comprising a plurality of light pixels and a plurality of dark pixels. The processor determines whether the image and machine readable code are the same size if they are not the same size, scales or crops the image or the machine readable code such that they are the same size. The processor associates each graphic code pixel with a corresponding image pixel, each pixel having a lightness value. The processor determines for each image pixel, based on a comparison between a lightness of the image pixel and a lightness of a corresponding graphic code pixel, whether to adjust the lightness of the image pixel based on one of a low threshold lightness value and a high threshold lightness value. The lightness value is adjusted for each pixel of the image which is to be adjusted to a modified lightness value, such that a combination of the image and the graphic code is produced.

Abstract: Example implementations relate to emulating 3D texture patterns in a printer system. One example implementation receives an image having a number of image pixels and selects from a plurality of digital substrates which each correspond to a physical substrate. Each digital substrate has luminance change data corresponding to heights of a 3D texture pattern at respective locations of the physical substrate. An image having emulated 3D texture is generated by adjusting the luminance of the image pixels corresponding to respective locations of the physical substrate and according to the corresponding luminance change data.

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 an example, a method includes, by one or more processors, acquiring a dot pattern having a distribution of dots. A greyscale image comprising a plurality of pixels each associated with a greyscale value may be derived from the dot pattern. Deriving the greyscale image may comprise assigning a greyscale value to each pixel, wherein the greyscale value is based on the distance associated with that pixel.

Abstract: In an example, a method includes, by one or more processors, acquiring a dot pattern having a distribution of dots. A greyscale image comprising a plurality of pixels each associated with a greyscale value may be derived from the dot pattern. Deriving the greyscale image may comprise, for each pixel, determining the closest dot to the pixel and associating a distance of the closest dot from the pixel with the pixel, and assigning a greyscale value to each pixel, wherein the greyscale value is based on the distance associated with that pixel.

Abstract: In an example, printed circuitry comprises a digitally printed switch, the printed switch comprising a first contact element printed using conductive print agent on a first substrate portion and a second contact element printed using conductive print agent on a second substrate portion. An interposed non-conductive printed spacer element is overprinted on at least one of the first and the second substrate portions.

Abstract: In an example, a method includes, at least one processor, in response to each of a plurality of requests, determining a halftone screen. Determining the halftone screen comprises encoding a signature pattern in the halftone screen, and halftone screens for different requests may be encoded with a different signature pattern. The halftone screen may be arranged such that, when applied to image data to provide a printed output, the pattern is discernible therein to provide a signature for the printed output.

Abstract: In an example, a method includes receiving, at a processor, a digital version of an image combined with a machine readable graphic code. Areas of the combined image and graphic code that have a lightness level below a threshold level may be determined. Print instructions for depositing a metallic pattern wherein solid areas of the metallic pattern correspond to the areas of the combined image and graphic code that have a lightness level below the threshold level may also be determined.
