Abstract:
Color imparting compositions for ink jet printer inks, as well as inks with such color imparting compositions therein, which can be used in a commercially available ink jet printer or the ink jet printer of a postage metering system to print machine readable information based indicia, such as postage, on a substrate, such as an envelope, are disclosed. The color imparting composition includes a water soluble black colorant material adapted to absorb light in a wavelength range between about 400 to 650 nm, such as Reactive Black 31 dye or Direct Black 195 dye, and a water soluble cyan colorant material having a molar extinction coefficient of at least 10,000 at a wavelength maximum in the range of about 580 to 750 nm, such as Direct Blue 307, Direct Blue 199 or Acid Blue 9. The weight ratio of the black colorant material to the cyan colorant material in the color imparting composition is in the range of about 50 to 1 to about 5 to 6.

International Classification:
B41J 29393
US Classification:
347 19, 347 14
Abstract:
A method for assigning unique printer resolutions or signatures, i. e. , a unique number of dots per inch, to a class, or models of printers or lines of postage meters. The number of dots per inch or resolution may be specified within a image on a document or within a postal indicia and later checked to determine if the image on document or the postal indicia has the correct resolution. The foregoing would be able to detect an image or postal indicia that was scanned into a computer and printed with a printer that did not have the number of dots per inch specified in the image or postal indicia.

US Classification:
347 40, 347 14, 347 19
Abstract:
The number of dots per inch or resolution may be specified within a image on a document or within a postal indicia and later checked to determine if the image or document or the postal indicia has the correct resolution. The foregoing is accomplished by specifying that the image on the substrate will be printed with n plus m dots per inch; rotating a ink jet head having n nozzles per inch about a axis parallel to a substrate by an angle so that the ink jet head will produce an image on the substrate having (n/cos ) dots per inch; storing in a data center that the specified image will be printed with (n/cos ) dots per inch; analyzing the image to determine if the image has (n/cos ) dots per inch; and comparing the number of dots per inch in the analyzed image with the number of dots per inch stored for the specified image to determine if they have the same number of dots per inch.
Method For Preventing Counterfeiting Of Articles Of Manufacture

Assignee:
Pitney Bowes Inc. - Stamford CT
International Classification:
H04L009/00
US Classification:
713179, 713176, 705 59
Abstract:
A method for verifying the source of an article of manufacture. A label having information relating to the article is prepared and digitally signed or otherwise encrypted to authenticate the information. The label and a tangible representation of the digital signature or other encrypted information are then securely associated with the article. The information relating to the article can include verifying information such as an expiration date, unique identification of the article, identification of an authorized provider of the article or a description of the article to protect against unauthorized use of duplicate labels. The label can also include an unreproduceable pattern such as a pattern of magnetic fibers embedded in the label and a digitally signed description of the pattern.

US Classification:
3405721, 340571, 340539, 3405728, 700225, 705408
Abstract:
Radio frequency identification tags are placed on mail contained in trays or tubs to locate and reroute mail that is misdirected, i. e. , being routed to the incorrect destination. The method involves the carrier reading the identifying information contained in the radio frequency identification tags on each mail piece while each mail piece is in the trays or tubs and removing one or more mail pieces in the tray or tub that are to be routed differently than that routing information contained on the outside of the trays or tubs.
Method For Determining The Information Capacity Of A Paper Channel And For Designing Or Selecting A Set Of Bitmaps Representative Of Symbols To Be Printed On Said Channel

International Classification:
H04N001/40
US Classification:
358 326, 358 115
Abstract:
A method for determining the information loss or conditional entropy in a paper channel where an imager produces an output from symbols printed on a substrate and a paper channel designed in accordance with such method. A parametric, statistical model of the channel is chosen. Test patterns are then transmitted through the channel to determine optimal parameter values for the model. These values are the used in the model to estimate the information loss in the channel. This information loss is used as a figure of merit in making design choices for the paper channel.

US Classification:
382101, 23546209, 2354621, 23546211
Abstract:
A method for detecting a copy of a composite image that includes a first image and a second image that has information embedded in the second image that will change in appearance when the first and second images are scanned or photocopied. The foregoing is accomplished by scanning the first and second images, and detecting a change in appearance of the second image that indicates the first and second images were scanned or photocopied.

International Classification:

US Classification:
382100, 382103, 382112
Abstract:
The disclosure describes an authentication system and related methods for authenticating printed objects. The system uses an information-based metric along with one or more print quality metrics to provide accurate detection or classification of a counterfeit printed object. The print quality metric evaluates attributes of a subject image associated with the original printer, ink or paper to detect degradation of those operations due to copying operations like an image scanning and halftone printing subsequent to the original printing of the object. The information-based metric measures message symbol errors in an optically readable code, such as a digital watermark.
