  • Publication number: 20200122116
    Abstract: In an example, a print system include a component device that is operation in a number of state, a density engine, and a component engine. An example density engine identifies a plane region of a plane where print fluid is to be printed based on data of a print job and determines a density classifier for the plane based on a location of the plane region on the plane. An example component engine causes an adjustment of a component attribute of the component device based on the density classifier.

  • Patent number: 10596814
    Abstract: According to an example, a printing apparatus may include two drop ejecting elements, a fluid circulating element, and a logic device. The logic device may determine whether one or both of a first drop ejecting element and a second drop ejecting element have been fired within a predetermined period of time prior to a current time. In response to the determination, the logic device may selectively transmit an output signal that is to cause the fluid circulating element to be selectively fired, in which the fluid circulating element is positioned to circulate fluid adjacent to both the first drop ejecting element and the second drop ejecting element.

  • Patent number: 10602020
    Abstract: In some examples, dynamic threshold based error diffusion may include determining whether a pixel associated with a pattern to be printed includes a lighter tone or a darker tone compared to an adjacent pixel. In response to a determination that the pixel associated with the pattern to be printed includes the lighter tone or the darker tone compared to the adjacent pixel, a firing threshold may be respectively increased or decreased to respectively decrease or increase a likelihood of printing of the pattern.

  • Publication number: 20200042163
    Abstract: Various systems and methods are provided that display various geographic maps and depth graphs in an interactive user interface in substantially real-time in response to input from a user in order to determine information related to measured data points, depth levels, and geological layers and provide the determined information to the user in the interactive user interface. For example, a computing device may be configured to retrieve data from one or more databases and generate one or more interactive user interfaces. The one or more interactive user interfaces may display the retrieved data in a geographic map, a heat map, a cross-plot graph, or one or more depth graphs. The user interface may be interactive in that a user may manipulate any of the graphs to identify trends or current or future issues.

  • Patent number: 10540747
    Abstract: Examples include computing devices, processes, and/or machine-readable storage mediums. Examples analyze a region of pixels for a digital image to determine a set of diagonal direction pixel differences corresponding to a target pixel. Examples analyze the region of pixels to determine diagonal variances corresponding to the target pixel. Examples scale the digital image by processing the target pixel into a set of subpixels based at least in part on the set of diagonal direction pixel differences and the diagonal variances.

  • Patent number: 10326911
    Abstract: A system, method, and non-transitory computer readable medium are disclosed for mitigating dot placement errors for a given print job. The method includes processing tone values on a per pixel basis to determine whether to implement plane dependence. Plane independence is implemented if the tone value exceeds a predetermined threshold. The method may be performed on a pixel by pixel basis and/or a print object or region basis. Determining whether to implement plane dependence may involve de-asserting or partially de-asserting a plane dependence component of an executed half-toning instruction between sequentially processed color planes of a printing system.

  • Publication number: 20190111619
    Abstract: In an example implementation, a method of printing a three-dimensional (3D) object includes scanning a print bar in a first direction over a build platform of a 3D printer to deposit a liquid agent onto a layer of build powder. The print bar is then indexed in a second direction substantially orthogonal to the first direction before scanning the print bar back over the build platform in a third direction opposite the first direction to deposit additional liquid agent onto the layer of build powder.
