Abstract: Artwork carrying machine readable data is generated by editing artwork according to a data signal or transforming the data signal into artwork. The machine-readable data signal is generated from a digital payload and converted into an image tile. Artwork is edited according to the image tile by moving graphic elements, adapting intersections of lines, or altering line density, among other techniques. Artwork is generated from the data signal by skeletonizing it and applying morphological operators to a skeletal representation, such as a medial axis transform. Artistic effects are introduced by filtering the data signal with directional blurring or shape filters.

Abstract: Digital watermarking is adapted for the variable data printing. A reference signal serves as a proxy for optimizing the embedding a watermark in a host image to be printed. Using the reference signal, embedding parameters are generated, which are a function of constraints such as visual quality and robustness of the machine readable data. Adjustments needed to embed a unique payload in each printed piece are generated using the embedding parameters. These adjustments are stored in a manner that enables them to be efficiently obtained and applied within the RIP or press during operation of the press. Various other methods, system configurations and applications are also detailed.

Abstract: In an example, a capture system includes a content capture mechanism, an isolation engine, a mark strength engine, and a parameter controller. In that example, the isolation engine generates mark data, the mark strength engine identifies a first variance level in a first region of a first set of mark data, and the parameter controller adjusts a parameter of the content capture mechanism in accordance with a strength change based on a comparison of the first variance level to a second variance level in a first region of a second set of mark data.

Abstract: This disclosure relates to advanced signal processing technology including signal encoding. One combination disclosed in the description is an image processing method comprising: accessing a design file to obtain image data, the image data comprising a plurality of color separations or channels, in which the image data comprises at least a 1D or 2D barcode represented therein and a first encoded signal encoded therein, the 1D or 2D barcode comprising a first plural-bit code and the first encoded signal comprising a second plural-bit code; operating a barcode reader to analyze the image data to decode the 1D or 2D barcode to obtain the first plural-bit code; operating a signal decoder to analyze one or more combinations of color separations or channels of the plurality of color separations or channels to decode the first encoded signal to obtain the second plural-bit code; determining whether the second plural-bit code conflicts with the first plural-bit code; and identifying a conflict based on said act of determining. Of course, other features and combinations are described as well.

Abstract: A watermark adjustment method and a watermark adjustment device are provided. The method includes determining whether a user clicks on a watermark preview interface in a predetermined manner; when it is determined that the user clicks on the watermark preview interface in the predetermined manner, generating a text box control according to a watermark pattern that is currently displayed to activate a watermark preview editing status; displaying the watermark pattern on the text box control; determining a text box display parameter according to a user setting for the text box control; and when the watermark preview editing status is ended, adjusting the watermark pattern according to the text box display parameter and displaying the adjusted watermark pattern in the watermark preview interface.

Abstract: The present disclosure relates generally to data hiding for retail product packaging and other printed objects. One embodiment embeds an information signal in a spot color for product packaging. The spot color is screened, and overprinted with process color tint. The tint is modulated prior to overprinting with optimized signal tweaks. The optimization can include consideration of a detector spectral dependency (e.g., red and/or green illumination). Many other embodiments and combinations are described in the subject patent document.
