| 20080229973 | Ink compositions and printing methods for high readability on various types of substrates - New blue inks are provided for inkjet printing, especially using piezoelectric printers, on papers which are typically difficult to print with good quality, high-contrast images. The inks are characterized by a color of the ink (color illumination D65) of L*: about 37±5, a*: about 7±7, b*: about −27±8. The inks contain an aqueous vehicle including water and a humectant comprising a polyhydric alcohol, a penetrant, surfactant, and a blue dye. The relative amounts of the aqueous vehicle, the penetrant, the surfactant and the blue dye, are effective to provide an ink having a viscosity and surface tension effective for inkjet printing, especially for piezoelectric printing, having a viscosity of from about 2 to about 4 mPa·s and a surface tension of from 30 to 50 mN/m. Also provided are a process for printing an image and a printed image prepared using the ink. | 09-25-2008 |

The inks contain an aqueous vehicle including water and a humectant comprising a polyhydric alcohol, a water-soluble polymer effective to improve the “hold out” properties of the dye-based ink on paper, surfactant, and a blue dye. The relative amounts of the aqueous vehicle, the water-soluble polymer, the surfactant and the blue dye, are effective to provide an ink having a viscosity and surface tension effective for inkjet printing, having a viscosity of from about 2 to about 4 mPa·s and a surface tension of from 30 to 50 mN/m.

| 20090169747 | RED-LUMINESCENT INK JET PRINTING COMPOSITIONS AND METHODS FOR IMPROVED WATERFASTNESS - Described are compositions and methods effective to improve the security obtainable for red phosphorescent inks printed, such as by ink jet printing. Specially designed polymeric chelating agents are water soluble and have a high chelating efficiency for lanthanide cations and are themselves strongly adsorbed on polymeric substrates, especially paper. The polymeric chelating agents comprise a polymer chain of either general formulae (1) or (2) containing pyridine-N-oxide, quinoline-N-oxide or isoquinoline-N oxide pendent ligand groups A, where m and n are independent integers in the range of from 1 to 10, and the number average molecular weight of the polymers lies in the range from 1×10 | 07-02-2009 |
| 20090248654 | SYSTEM AND METHOD FOR PROCESSING MAIL USING SENDER AND RECIPIENT NETWORKED MAIL PROCESSING SYSTEMS - Systems and methods for allowing the sender of a mail piece to obtain an accurate recipient address for the mail piece when the mail piece is being prepared are provided. The mail processing systems of the sender and recipient businesses are networked such that communication can occur between them. When the sender is preparing a mail piece for delivery to a recipient, the sender can participate in an interactive session with the recipient's mail room, utilizing the networked mail processing systems, to obtain a correct recipient address for a mail piece based on a database of recipient addresses maintained by the recipient's mail processing system. Since the mail piece is provided with an accurate recipient address, upon receipt of the mail piece by the recipient's mail room the mail piece can be properly delivered without requiring significant work by the recipient's mailroom to determine the appropriate intended recipient. | 10-01-2009 |
| 20100117350 | METHOD AND SYSTEM FOR VALIDATING A SECURITY MARKING - A method and system for authenticating an item by using a security marking. The security marking is provided on the item with an OVD ink capable of absorbing light in a visible wavelength range to appear visibly black and producing a red fluorescent emission under ultraviolet excitation. Under visible light illumination and ultraviolet excitation, a visible image and a fluorescent image are obtained from the security marking using image scanners. The images are compared to find a substantial match with each other. The security marking can be a postage indicium, a barcode, a symbol, a message or an image. The item to be authenticated can be a mailpiece, a banknote, a tag, a ticket, a document, an identification card, or the like. | 05-13-2010 |
| 20100155494 | PRINT CONTAINMENT OF PIXELS TO IMPROVE READABILITY - A method to improve the image of a printed barcode by causing controlled “bleeding” of the print pixels within solid printed areas surrounded by a barrier to improve the print contrast ratio within the barcode data element by homogenizing the printed data without causing image bleed into unintended areas. Hence, the printed material will contain more clearly defined printed and non printed areas to enable the printed material to be accurately read. | 06-24-2010 |
| 20100157007 | PRINT ENHANCEMENT OF PIXELS TO IMPROVE READABILITY - A method to improve the image of a printed barcode by enhancing coverage of the print pixels within solid printed areas to improve the print uniformity and decrease the graininess of the typical ink jet printing by dissolving a small percentage of the colorant and distributing more uniformly. The parameter improved by the invention is the graininess or uniformity of coverage. The contrast ratio within barcode data elements can be also improved without causing unwanted image bleed into unintended areas. Hence, the printed barcode will contain more clearly defined printed and non printed areas to enable the barcode to be accurately read. The invention prevents also unwanted bleeding in areas where it could lower the quality of the printed material by avoiding application of enhanced coverage facilitators when desired white space is identified within a minimum distance. | 06-24-2010 |
