A method for calibrating a digital stylus comprising imaging a portion of a calibration pattern area of a data encoding pattern using an imaging module of the stylus in order to generate calibration data representing an error in alignment for the stylus, and using the calibration data to adjust subsequent measurements from the stylus in order to compensate for the error.

Calibrating a digital stylus

A document processing system comprises a pattern generating systemarranged to generate a data encoding pattern, a printerarranged to print a documenthaving the pattern thereon, and a receiverarranged to receive data over a communication link. The pattern generating systemis arranged to generate the patternso as to encode data defining a communication parameter suitable for the transmission of data to the receiverover the link.

Patterns encoding communication parameters

A digital pen of the kind having means to sense and create a digital record of the use made of the pen and a memory in which the digitised record is stored also includes a reader for communication with memory tags by inductive coupling. The means to sense and create a digital record of the use made of the pen may include a camera. Preferably the reader for communication with memory tags is located at the opposite end of the pen from a nib for convention writing, and the pen includes a battery power supply.

A method of associating a first electronic document with a second electronic document comprising having a first physical paper identifier () having pen-readable coding () which codes for an identifier for the first electronic document, and reading the coding of the first electronic document with a pen () to acquire information enabling the identity of the first electronic document to be established, and communicating that identity to a computer processor (), and using the processor () to associate the identified first electronic document with the second electronic document.

Associating electronic documents, and apparatus, methods and software relating to such activities

A method and apparatus for producing a document having human-readable content and a position identifying encoding pattern. A printer places text or other content onto a substrate, such as paper, and a filter material application system applies transparent filter material to at least a portion of that content to only modify the reflectivity of the content at a predetermined wavelength. Because the reflectivity of the position identifying encoding pattern remains unchanged, it is distinguishable from the content and can be read at the predetermined wavelength. The position identifying pattern can take a number of forms including a number of dots printed at predetermined positions on the substrate on an imaginary grid.

A producthas a data encoding patternthereon. The pattern comprising a plurality of pattern cellseach of which has a pattern selected from a group of cell patterns. Each cell pattern comprises a plurality of cell elementseach of which can have any of a plurality of marking states, such that the marking states of the elements produce the cell pattern. Each cell pattern has at least two lines of symmetry. At least some of the cells are arranged in a manner which is dependent on the position of the content

A method for preparing a mask for multi-pass printing, comprises determining a characteristic satellite drop spray pattern for printing in a multi-pass mode with a printhead. Positions in the mask are filled with pass numbers. The pass numbers in a given position are selected based on considerations of interactions among main drops and satellite drops.

Method for preparing a print mask

A method of providing a copy of at least a portion of a document () comprising providing the document () with at least one document identifying indicia identifying at least a portion of the document, comprising the following steps, providing an indicia reader () to read the indicia on the document, reading the indicia with the indicia reader () and generating indicia data representative of the indicia, identifying the document (), and/or portion thereof, from the indicia data generated by reading the indicia; and obtaining an electronic copy of the document and/or portions thereof identified by the indicia data.

Method of obtaining at least a portion of a document

Conventional obstacles to entry and survival of small graphic-arts service providers are softened&#x2014;particularly for those businesses that operate as computerized 'ASP' enterprises involving wide-area networks&#x2014;by encouraging small operators to coexist effectively in use of a pivotal network-based service. One key mechanism promoting this capability is a system of optionally mutual links between the pivotal service and the ASPs. The service also counteracts a tendency in the industry to favor wastefully redundant vertical integration. On the other hand, the system also implements the prerogatives of an enterprise (such as a printing-broker ASP) that has an established customer, to closely channel the attention of that customer&#x2014;but subject, importantly, to being overruled by the customer. Ideally the system is carefully tuned to enable such customer action without unduly pressing the option upon the customer.

Open coventuring in a remote hardcopy proofing service, with preserved clientele, through interface sharing

Automatic testing determines whether a proofing-file generator and receiver are in a common intranet. If so then the proofing file is automatically sent by a route that is substantially wholly within the intranet, and ideally peer-to-peer. If the generator and receiver are not in a common intranet, then preferably the file is sent by a conventional route through the Internet, preferably via a master server of the proofing service. The test preferably includes dynamically establishing IP addresses for the generator and receiver, and comparing the established IP addresses; however, consultation of a pretabulated listing is also possible.
