    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.

    Abstract: A colorant for a printing apparatus is described. The colorant has a first component and a second component. The first component is configured to reflect radiation having a first set of wavelengths when the colorant is arranged on a substrate. The second component is configured to absorb radiation having a second set of wavelengths and emit radiation having a third set of wavelengths when the colorant is arranged on the substrate, the first and third set of wavelengths having at least one common wavelength.

    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.

    Abstract: A method for generating a color mapping for a printing apparatus is described. The printing apparatus includes a plurality of colorants including a first colorant configured to reflect radiation having a first set of wavelengths and a second colorant configured to absorb radiation having a second set of wavelengths and emit radiation having a third set of wavelengths. The method includes obtaining spectral characteristics for the plurality of colorants, computing a gamut of colors available to the printing apparatus and determining a color mapping from an input color space to an output color space.
