Abstract: Systems and methods are described for inline rendering of a color filter within a print job. A program associated with a printing system can select an overhead transparency media to serve as a color filter during inline print job finishing. A duplex path and finishing for the transparency media can be enabled on the printing system by the program. A first side of the overhead transparency media can be printed on with one or more colors by the printing system by the program. A transform can be used on a second side of the overhead transparency media to correct for front to back registration and includes one or more colors printed directly underneath colors printed on the first side by the program. The transparency medium including color filters can be inserted into pages of the print job, which can be rendered in the form of a bound book.

Abstract: A method, a system and a recording medium for rendering a macro gloss effect using a digital front end processor and a color printer having color marking materials involve defining a vector pattern cell, and creating a pattern ink based on the vector pattern cell. The pattern ink can be constrained to write at or near an ink limit at small sizes varying from a high toner pile to a lower toner pile within a pattern ink cell based on the vector pattern cell. One or more objects and a background can be then painted with the pattern ink to create a macro gloss effect image based on the pattern ink.

Abstract: A method of forming an article which includes a diffraction grating, an article, and an apparatus for forming the article by printing are described. The method includes forming a periodic structure by printing a first set of parallel lines on a first side of a transparent substrate with a marking material and printing a second set of parallel lines on a second side of the transparent substrate with a marking material, the first and second sets of lines, in combination, defining a grating having a frequency and a spacing between lines which causes incident light to be diffracted into a plurality of beams travelling in different directions.

Abstract: A method of forming an article including a diffraction grating includes forming a periodic structure by printing lines on a first side of transparent substrate with a toner. The lines have a frequency and a spacing which causes incident light to be diffracted into a plurality of beams travelling in different directions. The method can be used for forming reflective or transmissive diffraction gratings using xerographic printing techniques.

Abstract: A first pattern and the second pattern in an original include relatively lighter markings within a relatively darker background. The first pattern differs from the second pattern by including non-printing patches between the relatively lighter markings. When the original is exposed to ultraviolet light, the underlying print media fluoresces in response to the ultraviolet light at the non-printing patches, revealing hidden security printing features. When a scanned image is printed on a second sheet of print media to produce a copy of the original, the copy lacks distinct markings at locations where the relatively lighter markings and the non-printing patches appear in the original because the spacing interval of the relatively lighter markings and the non-printing patches is below the minimum resolution of the scanner. Thus, when the copy is exposed to ultraviolet light, the copy does not fluoresce the ultraviolet light where the non-printing patches appear in the original.

Abstract: An original document is formed using a first print medium by printing a first and second monochrome patterns with a single colorant to form printed first and second regions including first and second shapes, respectively, which are devoid of the colorant. The second shapes have a smaller size and a higher frequency than the first shapes. The first and/or second regions encode information. The first and second patterns and a fluorescence of the first print medium are selected such that the first and second regions of the original document are indistinguishable to the naked eye, under both normal and ultraviolet illumination but are distinguishable, only under the ultraviolet illumination, in a copy formed by scanning the original document and printing the scanned document on a second print medium with a plurality of colorants, to reveal the encoded information.

Abstract: A print device prints a document with a security marking in a microtext font. A scanning device scans the security marking, and an optical character recognition (OCR) engine attempts to recognize the characters in the security marking. The system the generates an encoding in which each character of the font is mapped to a character string made up only of characters that the OCR engine could recognize at or above a minimum recognition threshold. Then, when generating a new document with a new security marking in the microtext font, the system will use the encoding to replace each character in the security marking with its representation from the encoding so that the scanner and OCR engine can decode the security marking.

Abstract: A system generates a secure barcode and prints the secure barcode on a substrate. The barcode includes a first set of cells of a first color and a second set of cells of the second color. A first vector pattern is encoded onto pixels for first set of cells of the barcode, and a second vector pattern is encoded onto pixels that correspond to the set group of cells of the barcode. The vectors in each pattern will have substantially the same colors, thicknesses and frequencies, but will be out of phase with respect to each other. The system will generate a secure barcode that vectors of each pattern.

Abstract: A printable electronic document is received into a computerized device. The printable document contains original markings that can be printed on print media to produce a printed document. However, before printing, a computerized device adds first hidden markings to the printable electronic document. Such first hidden markings have a first vector graphic size. Further, the computerized device removes a pattern from the first hidden markings in the printable electronic document and adds (only to the removed pattern in the printable electronic document) second hidden markings that have the same vector graphic size as, but are out of phase with, the first hidden markings. Also, the computerized device adds geometrically shaped distraction markings to the printable electronic document. The geometrically shaped distraction markings have a second vector graphic size that is much larger than the first vector graphic size of the first and second hidden markings.

Abstract: To generate a security mark, a system prints test pattern marks of varying frequencies on a first substrate. The system copies the test pattern marks onto a second substrate. The system analyzes the copy to identify a frequency or period range for test patterns that exhibit a high level of contrast as compared to the original. It then uses the identified range to generate an array of cells having pantograph marks of various foreground/background frequencies/periods. The system prints the array and generates polygons that contain cells in which the foreground is visually distinguished from the background. The system identifies the polygon having an inner point having a largest range to edge. It identifies the frequency/period of the background pattern and of the foreground pattern of the cell that contains the inner point. It then generates a pantograph mark having a background and foreground that correspond the identified frequencies or periods.

Abstract: Methods and systems for forming a pattern ink pantograph. In an example embodiment, two or more pattern inks can be configured, such that a frequency of one pattern ink among the two (or more) pattern inks comprises a frequency below an MTF (Modulation Transfer Function) and a frequency of another pattern ink among the two or more pattern inks comprises a frequency above said MTF. The two or more pattern inks can be used as a special color space to paint a font or a geometric object, and such pattern inks are also independent of what is being written. Each pattern ink comprises vector graphic data.

Abstract: Methods and systems for rendering a gloss mark on a recording medium. Two or more sets of toner channels can be electronically created wherein each toner channel include respective sides and a bottom. The two or more sets of toner channels can be electronically configured to include a reflectance off the sides and the bottom of toner channels wherein one set of the toner channels is positioned at a different height and a different color than the other set of toner channels, thereby enhancing the gloss effect associated with a gloss mark, which allows the gloss mark to be effectively utilized in, for example, a printer or printing system such as an office class rendering device.

Abstract: An original has a first pattern on and a second pattern, and the first pattern and the second pattern include relatively lighter markings within a relatively darker background. The relatively lighter markings appear at a first spacing interval in the first pattern, and at a larger second spacing interval in the second pattern. The first pattern and the second pattern cover and equally block a region of the original from reflecting ultraviolet light. A scanner is only capable of detecting patterns of markings having a spacing interval larger than the first spacing interval, which causes a copy of the original to not include the relatively lighter markings appearing at the first spacing interval. Thus, the copy lacks markings at locations corresponding to where the relatively lighter markings appear at the first spacing interval in the original. The copy reflects the ultraviolet light more where the copy lacks markings.

Abstract: To troubleshoot an error, a printer uses a job ticket and printer-independent document data to perform a job, such as printing a document. The job ticket includes instructions for hardware component settings of the printer. In response to a capture bug command, the printer will capture, from a group of hardware configuration sensors, real-time values of the settings for the print device hardware components while the print device implements performs the job. The printer will save the captured real-time values of the settings, the job ticket, and the printer-independent document data to a merged file, and it will transmit the merged file to a maintenance service.

Abstract: A user interface of a printer displays instructions to use the printer's document scanner for scanning a sheet of print media (of a stack of print media being added to the paper drawer) in response to a drawer sensor detecting the opening of the paper drawer. The document scanner generates an electronic image of the sheet of print media from the scanning of the sheet of print media. The processor evaluates the electronic image of the sheet of print media to identify the media type and color of the stack of print media being added to the paper drawer. For example, this is done by evaluating the size, color characteristic, transparency, and reflection characteristic of the electronic image of the sheet of print media. Then, the electronic memory records that the paper drawer contains the stack of print media having a specific media type and color.

Abstract: A document contains a security element that combines a correlation mark and pantograph mark. The pantograph mark includes a dot pattern, part of which is printed to correspond to foreground pixels of the correlation mark, and another part of which is printed to correspond to background pixels of the correlation mark.

Abstract: A system prints a document using a device-independent pattern ink cell that is appropriate for the print device. The system does this by identifying an object in a print job corresponding to a security element that identifies a pattern ink cell for a color parameter. The system then defines a device-independent pattern ink cell for rendering the identified object. The definition of the device-independent pattern ink cell includes at least one scaling routine for adjusting a parameter of the device-independent pattern ink cell based on a resolution of a print device that will be used for printing the document. The system then queries and receives from a print system a device resolution of the print device, executes the at least one scaling routine to transform the device-independent pattern ink cell to yield a device-dependent pattern ink cell, and generates a print using the device-dependent pattern ink cell.
