    摘要: A streak detection method and system in a fixed imaging array digital scanning system obtains image data from each of the plurality of rows in the at least one full color spectrum channel set of rows of positionally discrete sensors and integrates this data to produce an estimate of image data recorded by at least one clear channel row of positionally discrete sensors. A clear channel error signal is generated by the comparison to alert the operator to the presence of non-image data. The clear channel error signal may be refined to through a low pass column filtering process in order to filter out potentially erroneous clear channel error resulting from thermal, mechanical or other noise sources unrelated to image scanning. Stationary obstructions in the field of view of the imaging array, or defects in one or more sensors in the imaging array, are detected through this comparison which would otherwise appear repeatedly reproduced as streaks or lines in the reproduced output image.

    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: 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: A toner set includes a plurality of toners, at least one toner but less than all toners of the toner set including binder, colorant and fluorescence agent and remaining additional toners including binder, colorant and free of fluorescence agent. At least a first toner grouping and a second toner grouping of the toner set form a combination, the first and second groupings of the combination exhibiting a substantially same color under ambient light conditions upon image formation. The first toner grouping and the second toner grouping of the combination contain a different amount of the fluorescence agent, wherein upon exposure to activating energy, the fluorescence agent fluoresces to cause a visible change in the color of a pattern formed in an image by the first toner grouping as compared to the second toner grouping.

    摘要: A method for avoiding objectionable moiré in a color image can include identifying a problematic excitation angle associated with a problematic excitation in a marking process or in the color image and selecting a set of at least two halftone screens for rendering at least two separations of the color image wherein the set of screens is selected to avoid including significant screen fundamental, harmonic and beat frequencies at angles closer than about 1 degree of the identified problematic excitation angle.

    摘要: Methods are provided for creating a fluorescent watermark within an image on a substrate, such as paper. The method involves creating a halftone image using two different halftone strategies. The halftone method is combined with a binary watermark mask to form two color patterns (e.g., one in a background region of the image and one in a watermark region of the image) and two successive-filling halftone algorithms, such that the ink droplets deposited by one color pattern cover more of the substrate than the ink droplets deposited by the other color pattern, with the two color patterns having approximately the same reflectance under normal light. However, under UV illumination, a visible difference (e.g., the watermark) is seen in the two patterns.

    摘要: Systems and methods are described that facilitate generating a background image with a UV-fluorescent watermark for printing on a document. A binary watermark mask is generated to separate the background image into the UV-active and the UV-dull regions. Based on the assigned binary value of the watermark mask, each pixel is assigned a UV-active or UV-dull color using an adaptive halftoning technique, in order to generate a binary UV-active image and a binary UV-dull image. A binary watermarked background image is generated by combining the binary UV-active and UV-dull images, and is printed on a document. The UV-active and UV-dull colors have different UV intensities under UV light, but are indistinguishable under normal lighting conditions. In this manner, the background image is visible when exposed to visible light, and the UV-fluorescent watermark is visible when exposed to UV light.
