A method of extracting data embedded in a 3D object includes a 3D scanning device scanning a 3D object and extracting data embedded as physical representations in the 3D object. A processing device will identify, from the extracted data, instructions for causing the processing device to perform an action such as identifying building instructions for printing a copy of the 3D object. The processing device will also perform the action to identify the building instructions, and cause a 3D printer to use the building instructions to print the copy of the 3D object. The processing device may be part of the 3D scanning device or part of another device or system that is in communication with the 3D scanning device.

Extracting an embedded database from a physical object

A method and system for embedding a database in a 3D object uses a 3D dimensional printing device and a computer-readable memory that stores a build sequence comprising instructions that, when executed by a processor, will cause the 3D printing device to form a three-dimensional object by depositing layers of build material and by including, in one or more of the layers, physical representations that represent a data set that includes a record of information for production of the 3D object.

A method of extracting data embedded in a 3D object includes a 3D scanning device scanning a 3D object and extracting data embedded as physical representations in the 3D object. A processing device will identify, from the extracted data, instructions for performing an action on the data such as: displaying at least a portion of the data, transmitting at least a portion of the data to an external database, transmitting at least a portion of the data to an external application, or receiving user input for handling the data. The processing device may be part of the 3D scanning device or part of another device or system that is in communication with the 3D scanning device. The method includes performing the action, and returning a result of the action to a user of an electronic device. It may also include receiving a user selection of the portion of the data.

According to exemplary methods, a selection of a paper type for producing an image is received. A database of background suppression values associated with paper types is searched. Responsive to not finding a background suppression value associated with the paper type, the database is updated for the paper type. According to the method of updating, a page of the paper type is scanned and image data obtained by scanning the page is analyzed. Background luminance for the page is determined based on analyzing the image data. A background suppression value is calculated for the page based on the background luminance. The paper type and the background suppression value for the page are added to the database. The background suppression value is associated with the paper in the database.

A method and system for embedding a database in a 3D object uses a 3D dimensional printing device and a computer-readable memory that stores a build sequence comprising instructions that, when executed by a processor, will cause the 3D printing device to form a three-dimensional object with an embedded data structure by depositing layers of build material and by including, in one or more of the layers, physical representations that represent a data structure.

When printing 3D objects a print file to be executed by a 3D printer to generate a 3D object is analyzed to identify candidate regions for insertion of printer ID information that identifies the printer printing the 3D object. Code describing the printer identification information is inserted into the print file at appropriate locations to cause the 3D printer to print one or more structures representing the printer identification information in one or more identified candidate regions. The printer identification information is printed by omitting or replacing one or more voxels in the printed object. Structures representing the printer identification information may include, e.g., barcodes, glyphs, alphanumeric sequences, etc. The printer identification information may include, e.g., a printer serial number and/or time stamp, manufacturer copyright and/or trademark information, etc.

An embodiment generally relates to systems and methods for determining a conversion location based on the content of a document and an intended quality level of the document. More particularly, processing logic can be configured to analyze a document submitted for rendering to determine a content level of the document. Further the processing logic can compare the content level to an intended quality level specified by a user of the document to determine whether to convert the document on local resources or in a cloud-based network. An associated conversion application in the appropriate location can convert the document into a printable format, and a print engine can render the converted document.

A method allows an end user to calibrate a color reproduction device with recording media brightness compensation. A color reproduction device includes a device for converting the native color values of the scanner into a device independent color space, a test target, the desired values of each patch of the test target and a printing device. The method includes printing the test target and scanning it with a scanner that forms a part of the color reproduction device. The device compares the desired values with the values obtained from scanning the printed test target to obtain a set of adjustment values to compensate for drift in the output of the color reproduction device. The compensation includes compensation for utilizing a recording media that does not have the same white characteristics as the recording media that was used to generate the scanner profile used in converting the scanner dependent color space values to a device independent color space values.

A method and system for processing image data provides associated background metadata in a searchable format and reduces file size. MRC techniques are used to process input image data. It is known that the image data may be segmented to generate a background layer representing background attributes of the input image data. A background color value of the background layer is detected, and background metadata representing the color value is generated. The background metadata is associated with the image data (e.g., as a separate file, in the image header, etc.), thereby making the background metadata searchable and reducing the file size of the image data to be stored.
