  • Publication number: 20190039294
    Abstract: The present disclosure relates a method of 3-dimensional printing a printed part. The method comprises printing an inkjet dopant composition at selected locations on a layer of build material comprising polymer particles. The inkjet dopant composition comprises a dopant dispersed or dissolved in a liquid carrier. Polymer particles at selected areas of the layer of build material are then fused to form a fused polymer layer comprising the dopant. The selected areas of the layer of build material include areas of the layer of build material that have not been printed with the inkjet dopant composition.

  • Patent number: 10184893
    Abstract: Examples relate to providing hyperspectral scanning of a surface. In some examples, motion capture data of unobstructed portions of the surface are captured, and spectral data of the surface are captured through a slit assembly and diffraction grating. The motion capture data are processed to determine a movement of a scanning device. At this stage, the spectral data are translated and rotated based on the movement of the scanning device to generate images that each correspond to a different color channel.

  • Patent number: 9313360
    Abstract: Certain methods and systems are described for encoding data in an image. According to an example, a set of metamers under a first set of conditions may be determined that vary under a second set of conditions. These may be used to generate a set of color mappings for a sampled color value, each color mapping being used for a different data value in the data. As such the data values may be detectable when the image is observed under the second set of conditions but not detectable when the image is observed under the first set of conditions.

  • Patent number: 9256815
    Abstract: Certain methods and systems are described that allow the spectral control of a print output. A plurality of colorants are used where one or more colorants contain nanoparticles. Each colorants has a specified spectral range corresponding to the constituent nanoparticles. To print with these colorants a spectral separation may be used that maps an input color with associated spectral information or direct spectral information to print control data, the print control data having defined values for depositions with each combination of the colorants. The spectral separation may be constructed by characterizing a set of spectral Neugebauer primaries for the plurality of colorants.
