Systems and methods for color reproduction tolerances are provided. One method according to the present disclosure may involve selecting a printing configuration, printing a color scale sample using the printing configuration, and scoring the printed color scale sample based at least in part on an extent to which transpositions of the color swatches occur over a color range. When the score of the printed color scale sample indicates a print quality is or will be above a threshold level of quality, a print job using colors of the color range may be printed using the printing configuration.

A system that generates risk values for a print service provider. The print service provider may calculate probabilities of an event occurring, calculate the effect that the given event will have on the print service provider, and determine various risks associated with calculations. These risks may then be utilized to determine overall operational strategies for the print service provider when compared to threshold risk levels for the print service provider.

Print service provider risks applied to decision making

Examples disclosed herein relate to categorizing a target word based on word distance. A processor may determine a difference level threshold for a category based on difference levels between words associated with the category and determine difference levels between a target word and the words associated with the category. If one of the difference levels of the target word is below the threshold associated with the category, the processor outputs the category.

Devices and methods for tracking a print job using an assignable electronic device on a print service provider (PSP) production floor are provided. One such method includes scanning a barcode-enabled job ticket assigned to a print job using a mobile electronic device assigned to a location on a print service provider production floor and sending barcode data from the barcode-enabled job ticket from to a PSP controller. The mobile electronic device may receive workflow instructions associated with the print job from the PSP controller. In addition, the mobile electronic device may display a representation of the workflow instructions.

An object is protected against counterfeiting by an article including an HVS-perceivable target and HVS-perceivable texture surrounding the target. The texture produces a gentle HVS stimulus modulation. Color of the target has a higher saliency than that of the texture, whereby the texture provides camouflage for the target. Location of the target with respect to the texture is a function of a serial number or other information about the object.

Anti-counterfeiting articles

A product package article has an HVS-perceivable security pattern on its surface. The security pattern is based on simultaneous color contrast. The security pattern can provide protection against counterfeiting.

An automated method for proofing a page for color discriminability problems includes converting a first color of a first object appearing on the page and a second color of a second object appearing on the page to coordinates of a color naming system. The method includes identifying a first color name of the first color and a second color name of the second color based on the coordinates. The method includes identifying whether the first color and the second color are discriminable based on the first color name and the second color name.

In a method of managing color output by appearance intent a color display value is received. The color display value comprises at least one appearance intent tag and is associated with an item of graphic content. The color display value is converted into an intermediate color value such that an appearance intent specified by the appearance intent tag is preserved in the intermediate color value. The intermediate color value is converted into an output color display value recognizable by an output device, such that the appearance intent is preserved in the output color display value.

A method and apparatus for market-based document layout selection use an automated auction or bartering system, i.e., an automated page layout system, to place objects within a page and automatically generate a page layout that is pleasing to a user. An object refers to any item that can be individually selected and manipulated, and may include shapes and pictures that appear on a display screen. The method and apparatus improve the quality of page layout in terms of user preferences, and optimize the speed at which various objects are arranged on a page in a pleasing manner. In addition, the resulting page layout may be consistent among pages because all pages are arranged according to a common algorithm.

A multi-component icon and system and method of generating thereof. The multi-component icon is generated from characteristics of a data object or data objects where the characteristics include data object content and data object metadata. The multi-component icon includes a plurality of visual traits. Each visual trait has a plurality of variations, such as different shapes, colors, and/or patterns. The visual traits are variably assignable to any one characteristic of the data object such that each variation of the characteristic is visually represented by the icon by a corresponding variation of the variably assignable visual trait. Multi-component icons are generated for groups of data objects, such as word processing files, by determining common characteristics between the files, assigning visual traits to the common characteristics, and then displaying the multi-component icons according to the assignments such that variations of the common characteristic between the files are symbolically show by variations of the assigned visual trait. Icon visual traits are interactive so as to indicate relationships between data object characteristics by 'dragging' one icon over another.

A color printing system includes a central processing unit for generating color image data, a color monitor for displaying color image data generated by the central processing unit and a color temperature sensing device for sensing color temperature of viewing light in which color images displayed on the monitor and color images printed by the printer are viewed. A first light source has a light output intensity controllable by the central processing unit. The central processing unit is adapted to control the intensity of the first light source in accordance with the color temperature sensed by the sensing device so as to match the color temperature sensed by the sensing device to a potential color temperature. Additionally, a second light source may be provided. The second light source has a different color temperature than the first light source and the central processor can adjust the intensity of the first and second light source based on relative color temperatures. The central processing unit is adapted to adjust the color temperature of either or both intensity of the first and second light sources.

In the present invention statistical methods are used to estimate the reflectance of the paper and align the tone gamut to the dynamic range of a digital input device such as a scanner during a single scan. The estimate is refined during the scan. This refinement increases the robustness with respect to unfavorable originals (e.g., originals with a dark border) and at the same time also can take into account such phenomena as the change of the response of the sensor due to thermal effect during slow scans. In the present invention no spatial information on the image is collected. Instead a histogram of the occurrence of each tone level is accumulated during the scan. The background color of the image, i.e., the tone value of the paper is estimated by analyzing the histogram. When this value is known, the parameters for a tone reproduction curve (TRC) can be calculated. The shape of the TRC is not altered by these parameters, i.e., the exposure can be controlled independently of the tone reproduction. This process is repeated from time to time during the scan to assure robustness and to compensate for drifts in the sensitivity of the sensor.

A template-type calorimeter comprising a light-transparent substrate having a diffraction grating on a surface thereof, the diffraction grating being operative to diffract light incident thereon from a spaced-apart aperture into its constituent spectral components. A template is provided on a surface of the substrate and arranged to receive the diffracted spectral components. The template has formed thereon at least three spatial filters, each for selectively transmitting diffracted spectral components in accordance with respective ones of the desired color-matching functions such as the CIE x(.lambda.), y(.lambda.), z(.lambda.) or r(.lambda.), g(.lambda.), b(.lambda.) color-matching functions. The diffraction grating and the template may be mounted on opposite sides of the substrate, or they may be mounted in a laterally spaced-apart relationship on the same side of the substrate, in which case the opposite side of the substrate is coated with a reflective material. Detectors are arranged adjacent and behind each spatial filter to detect the spectral components transmitted by the respective filters, and the entire assembly is mounted in a light-tight housing which houses the aperture and the assembly in the desired spaced-apart relationship.
