    摘要: A method and system for creating guilloché base pattern with two-dimensional periodicity in a plurality of replicate patterns is shown wherein the creating can be assessed in real-time for pattern acceptability by a user. A base pattern is set on an imaging device in vector space relative to a set of predetermined pattern nodes. The base pattern is modulated via a user interface by adjusting positions of the pattern known for selectively controlling curve shapes of the pattern. A guilloché mark is illustrated by display on the imaging device of the adjusted base pattern and a compilation of associated replicate patterns for user assessment of the mark.

    摘要: What is disclosed is a system and method which addresses the problem of inheriting color management intent from a fleet color management LUT into a 4-to-4 cascaded LUT. The LUT is updated starting with a set of patches that either form a uniform or non-uniform grid of the LUT or can be projected to a uniform or non-uniform grid in the CMYK space using, e.g., PCA. A set of L*a*b* target as well a variable that serve the purpose of preserving the GCR and other elements of the fleet profile is obtained by passing the set of CMYK values to the fleet printer model. By iterating on the printer (or the printer model of the engine at the moment of the engine change) and converging to the targets, the engine device cmyk set is obtained. The LUT is formed between the uniform or non-uniform gridded CMYK and the device cmyk.

    摘要: A system and method for infrared watermarking using gray component replacement and other color removal schemes is shown. This method includes providing a substrate and implementing two infrared absorption strategies, one with low infrared absorption and the other with high infrared absorption. These two strategies are then combined in order to form two gamuts with substantially similar shapes. This combination can be made by blending the gamuts at areas where one of the strategies do not meet or implementing the intersection of the two gamuts. A watermark is then printed along with an image. The resultant image with watermark is void of artifacts while still having a consistent watermark signal.

    摘要: A halftone cell is composed of a plurality of pixel groupings predefined to correspond to optimal tone level gradations. Selected output pixel groupings vary in number, and in shape of subpixels used from other pixel groupings, in order that successive input levels correspond to successive halftone cells defining substantially equal changes in a measured darkness value. Tone level gradations are optimized by purposeful correlation of input levels to output levels, especially where the number of output levels exceeds the number of input levels. During optimization, a calibration sample is produced by the image output device and calibration elements are empirically measured. Darkness change between successive levels is calculated and compared. Where the percentage of darkness change exceeds a desired amount, additional calibration elements are produced until the change calculated between successive levels is substantially the same. Successive input levels are associated with successive output levels such that a change between any adjacent input levels produces a change in darkness in the desired amount. The correlation is stored in a look up table for use during operation of the image output device.

    摘要: The invention provides a system and method for reducing or eliminating kinks in ink limit conversion processes. In particular, an adjusted ink limit conversion process is provided which approaches the limit in a smooth fashion. Moreover, extrapolated values in the input, values that are outside of a predetermined range, are handled in a smooth fashion. The extrapolated values are used to avoid kinks in the conversion process at the end bounds of the range. Ink limiting is performed gradually as the system approaches the ink limit, avoiding sudden changes in the slope of the system response characteristics. If one of a plurality of colors reaches zero ink, the remaining colors are decreased by multiplying them by a factor less than one. Accordingly, the colorant ratio is maintained, and hue shifts are reduced.
