摘要： As set forth herein, computer-implemented methods and systems facilitate watermarking documents and/or images using 2nd generation stochastic halftoning. The watermark is used to spatially vary the gray level at which a frequency modulation-to-amplitude modulation transition occurs. The encoding algorithm uses as inputs a contone image and a watermark. The visibility of the watermark is controlled by the magnitude of the difference between the AM-to-FM transition threshold values.

摘要： A system for generating a security mark includes a data reception component that receives information. A security mark generation component in communication with the data reception component generates at least one security mark configuration based at least in part upon the received information. The at least one security mark configuration includes at least one simulation mark which resembles a natural feature. An application component applies one configuration of the at least one security mark configurations to a recipient. The applied security mark configuration obeys at least one rule whereby the security mark is distinguishable from the natural feature which it resembles by a system for detection of security marks.

摘要： A process for creating a barcode with an embedded logo considers a printer gamut and divides the printer gamut into multiple regions. A virtual printer gamut is then generated with the colors in bright and dark regions. A target logo image is generated by mapping the virtual gamut to the original logo image. A logo with embedded barcode is produced using the colors specified in the target logo image.

摘要： As set forth herein, computer-implemented methods and systems facilitate the generation of halftone screens for moiré-free color halftoning. A first fundamental frequency vector and a second fundamental frequency vector of a halftone cell are sheared using a selected shearing value. The shearing value is selected as an offset in a fast scanning or slow scanning direction. The selected shearing value satisfies various moiré-free conditions associated with the identified frequency vectors and is capable of being selected for multiple halftone screens. The halftone screens generated using the sheared frequency vectors are used for moiré-free halftoning.

摘要： As set forth herein, computer-implemented methods and systems facilitate halftoning using a parametrically controlled spot function based on triangle tessellation, which in turn facilitates dot growth control of periodic halftone using an irregular seed structure. The spot function determines the shape of the halftone dot used to reproduce a given pixel. The spot function is well suited for growing halftone dots arrayed on a non-regular grid and can also be used for grids with regular order. The spot function includes adjustable parameters for controlling its sharpness and slope.

摘要： As set forth herein, computer-implemented methods and systems facilitate employing a single stochastic screen defined up to a specified transition level. The dots at the specified level are connected to form a triangle tessellation with an associated spot function. For up to three colorants, a vector screening technique is employed, which involves a first colorant dot being grown from the vertices, second colorant dot grown from the triangle center, and a third colorant dot grown from the side midpoints. Growth in this manner ensures separation of colorants up to a certain density level. In cases where fourth colorant is to be used at a given pixel, the fourth colorant can be added using methods typically used for clustered screens, such as stochastic screening of the lightest colorant, in order to mitigate color shift sensitivity issues.
摘要翻译：如本文所述，计算机实现的方法和系统便于采用在特定过渡级别之下定义的单个随机屏幕。指定级别的点被连接以形成具有相关联的点功能的三角形细分。对于最多三种着色剂，使用载体筛选技术，其包括从顶点生长的第一着色剂点，从三角形中心生长的第二着色剂点和从侧面中点生长的第三着色剂点。以这种方式生长确保着色剂的分离达到一定的密度水平。在给定像素处使用第四着色剂的情况下，可以使用通常用于聚类屏幕的方法（例如最轻的着色剂的随机筛选）来添加第四着色剂，以减轻色移敏感性问题。
