摘要： A method and apparatus are provided for compensating for spatial non-uniformities in a printer by deriving a true spatial non-uniformity tone response curve (TRC) that characterizes the printer in terms of color output variation for each addressable pixel location in a spatial range. The “true average” tone response curve is determined for a color channel. A prediction of the true response as a function of the spatial location is derived by printing and scanning a specially designed halftone-independent target of binary patterns. The predicted tone response curve for each color channel and halftone is predicted using a binary printer model, wherein the “predicted tone response curve” provides a model based approximation of the actual response for each addressable pixel location in the spatial range. Also stored is an “average predicted tone response” by averaging the “predicted tone response curve” over the spatial range of the printer.

摘要： Systems and methods are described that facilitate reducing a number of patches used in characterizing a color halftone printer via a binary color printer model. A binary printer model involves printing of a fundamental set of color binary patterns that encompass all possible halftone outputs. A k-center clustering technique is employed to automatically find and eliminate redundancies in the initial set of binary color patterns. Once the number of patches is reduced to an acceptable number, a multiplicative reflectance model is applied that better approximates the physical process and therefore improves accuracy.

摘要： As provided herein, there are supplied teachings to systems and methods for resizing a digital uniform rosette halftone image composed of multiple colorant separations, by using uniform rosette halftone tile parameters and iterative determination of energy metrics. One approach entails receiving into a digital imaging system, a digital uniform rosette halftone image and a desired resizing factor for that digital uniform rosette halftone image. Subsequently the system will define uniform rosette screen parameters to define uniform rosette Holladay halftone tiles within the color uniform rosette digital halftone image. From the defined uniform rosette cells, a number of uniform rosette halftone tile seams are determined for manipulation. The orientation of the number of uniform rosette halftone tile seams is dictated by the received desired resizing factor. The energy of the number of uniform rosette halftone tile seams is determined according to an energy metric so as to provide indication of low energy determined uniform rosette halftone tile seams. A resizing of the uniform rosette halftone image by iteratively deleting a number of the low energy determined uniform rosette halftone tile seam is performed so as to obtain a resized uniform rosette halftone image. The resized uniform rosette halftone image may then be printed on a printer.

摘要： Disclosed herein is a method and apparatus for moiré-free color halftone printing with up to five color image separations. The method and apparatus utilize a plurality of non-orthogonal halftone screens to produce outputs that are moiré free and form rosettes.

摘要： Provided herein are teachings directed to the creation of moiré-based auto-stereoscopic watermarks in rendered images. By choosing different halftone structures, which differ by having different spatial frequencies for each of two delineated partitions in an image, it becomes possible to embed arbitrary binary patterns into printed documents as digital watermarks. The invisible watermarks become moiré auto-stereoscopic images when the prints are viewed through an overlaid transparency “decoder” suitably prepared by virtue of being rendered with a uniform halftone structure having the correct special frequency in relationship with the partition frequencies employed in the printed document.

摘要： Disclosed herein is a Moiré-free color halftone configuration for clustered dots. Unlike conventional methods, the disclosed method produces periodic hexagon rosettes of identical shapes. These exemplary hexagon rosettes have three fundamental spatial frequencies exactly equal to half of the fundamental frequency of the three halftone screens. The resultant halftone outputs are truly Moiré free, as all the fundamentals and harmonic frequencies are multiples of and thus higher in frequency than the rosette fundamental frequency. The halftone outputs resulting from the employment of the exemplary rosette design methodology provided herein, are also robust to the typical misregistration among color separations commonly found in color systems.
