摘要： Moiré free color halftoning is achieved through the use of two dot screens and one or two line screens. The line screens may be, for example hybrid line screens. Frequency vectors associated with the screens combine to produce moiré frequency vectors representing moiré frequencies above or below the visual range. In one embodiment lines screens are used to halftone yellow and black separations and dot screens are used to halftone cyan and magenta separations. The dot screens are oriented at 15 and 75 degrees. The line screens are oriented at 45 and 135 degrees. Selected screens and screen orientations minimize screen interaction with mechanical or optical artifacts of a rendering device, thereby minimizing mechanical and optical moiré.

摘要： A digital image processing method. The method includes printing a first set of reference marks on one side of a substrate with a first print engine; printing a second set of reference marks on the same side of the substrate as the first set of reference marks with a second print engine; sensing both sets of reference marks on the substrate with an image sensing unit and generating a digital image of the reference marks; performing image analysis on the digital image to obtain an image-to-image distortion map where the image-to-image distortion map is a local measure of difference between the first set of reference marks and the second set of reference marks; and generating a compensated customer image by using the image-to-image distortion map to reduce registration errors when using the first and second print engines.

摘要： A watermark is provided for use with images or image portions, such as saturated text. The watermark is provided as a modulation to the optical density of a public image or image portion wherein both modulated and unmodulated portions of the public image or image portion have an optical density that is beyond a threshold optical density beyond which the human visual system has a low sensitivity to optical density variations. Alternatively, the modulation is made at such a low amplitude as to be difficult to perceive by the human visual system. The modulation may be applied via an overprinting operation. Alternatively the modulation may be applied to image data prior to printing.

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.
