A water based colorant that includes a polymer emulsion and semiconductor crystals capable of emitting light. The colorants include paints, inks and/or dyes can be applied to various substrates.

Water based colorants comprising semiconductor nanocrystals and methods of making and using the same

A system and method for distinguishing a first light source from other light sources utilizes an image receiver that can selectively engage and disengage a filter. The filter can be configured to either block bands of light corresponding to the light being emitted by either the first source or the other sources. By sequentially engaging and disengaging the filter from the image receiver, the first light source may be distinguished from other light sources.

System for the recognition of an optical signal and materials for use in such a system

A system and method for distinguishing a first light source from other light sources utilizes an image receiver that can selectively engage and disengage a filter. The filter can be configured to block bands of light corresponding to the light being emitted by either the first source or the other sources. By alternately engaging and disengaging the filter from the image receiver, the first light source may be distinguished from other light sources.

Systems and methods for optimizing the process of segregating undesired mail using an incoming mail sorter are described and in certain examples, systems including those for using information feed-forward and/or feedback systems for making selective physical delivery decisions in the process of sorting and delivering incoming physical mail are described.

Systems and methods for segregating undesired mail

In accordance with an embodiment of the invention, a method for creating a self-authenticating document is disclosed. The method comprises: providing a base substrate forming the document; printing an authentication seal on the document, the authentication seal comprising a printed portion comprising an ink creating a bleed area on the document where the ink and the substrate interact; and obtaining unique bleed properties of the bleed area. The bleed properties are obtained by scanning the bleed area upon termination of bleeding or drying to provide a description of the ink and substrate interaction to generate an identifier code representing the unique bleed properties. The method further comprises generating a signature of the identifier code, encoding the identifier code in an information carrier, and associating the information carrier with the document or storing the signed identifier code in a remote verification seal code that is not printed on the document. The authentication seal is capable of being scanned and compared to the information carrier or to the remote verification seal code, wherein the verification seal code is not located on the document and comprises the same code information as the identifier code.

A water-based ink for use in an ink jet printer for printing machine-readable indicia on a substrate is disclosed. The ink jet ink comprises fluorescent nanoparticles having a diameter between about 30 nm and about 100 nm; and an aqueous liquid vehicle. The aqueous liquid vehicle comprises water and a water soluble vehicle in sufficient amounts to achieve an ink viscosity and surface tension effective for application of the ink jet ink to the substrate in a predetermined pattern by ink jet printing.

Fluorescent ink

A printer luminescent ink sensor for a printing device including a radiant energy source; and a photodetector located downstream from a print head of the printing device. The photodetector is adapted to detect luminescent energy from an indicium printed by the print head, upon exposure to radiant energy from the radiant energy source, substantially immediately after the indicium is printed.

Fluorescent ink detector

A card for testing print heads includes a first layer having a first height and longitudinal length and a second layer located on top of the first layer having a second height and longitudinal length smaller than the first length. Also, a method of determining ink drop velocity including providing such a card, and printing a line including a plurality of dots thereon. A first of the dots is located on the first layer and a second of the dots is located on the second layer. Finally, the method includes determining a first relative distance between the first and second of the dots along the print direction, determining a second relative distance between the top surfaces of the first and second layers, and calculating the ink drop velocity as follows: V*(RD/RD), wherein V is the print velocity, Dis the first relative distance, and Dis the second relative distance.

In accordance with one embodiment, a tamper resistant envelope comprises a first panel with an interior and an exterior side. The envelope further comprises a second panel attached to the first panel to define an interior portion having opposite side edges, a closed edge portion and an opening portion opposite the closed edge portion to provide access to the interior portion of the tamper resistant envelope; and a flap for sealingly adhering to an exterior surface of the first panel. The flap has an interior and an exterior side and is attached to the second panel at an edge of the second panel opposite the closed edge portion. The flap comprises thereon a first adhesive layer on the interior side of the flap comprising a first remoistenable adhesive deposited on the flap; a solid dye deposited on a portion of the first adhesive layer, wherein the dye is not visible on the exterior side of the flap; and a second adhesive layer comprising a second remoistenable adhesive deposited over the dye to encapsulate the dye. The dye is capable of being released upon contact with steam to provide a visual indication of the dye and an indication of tampering.

Tamper resistant envelope

A method and apparatus for embedding information in an image during relative movement between a print medium and an ink jet print head is provided. A plurality of first lines are printed and a plurality of second lines are printed. Each of the first lines includes a plurality of first dots and a plurality of second dots offset from the first dots by a first amount, and each of the second lines includes a plurality of third dots and a plurality of fourth dots offset from the third dots by a second amount different than the first amount. The information is encoded in the image using an encoding scheme in which the first lines represent a first value in the encoding scheme and the second lines represent a second value in the encoding scheme.
