摘要： A dual level encryption method, and document, for providing and obtaining a substantially increased amount of optically readable information from an otherwise conventional and highly visible printed bar code pattern area on a document without interfering with the conventional optical reading of the conventional information in the bar code, comprising integrally printing a second and very much finer pattern of encoded optically machine readable glyph code or other such indicia within the bar code pattern area, containing a much higher level of information, to provide two different levels of information within the same area. Scanning the bar code pattern with a conventional bar code reader extracts conventional bar coded information embedded in the bar code without interference from the second indicia. Scanning the same bar code pattern area with a different, higher resolution, optical scanner extracts the much greater amount of information from the second, much finer, optically readable indicia pattern.

摘要： A method and apparatus for overloading operators in Page Description Language (PDL) defined graphics redefines the graphic, such as to compensate for certain undesirable line growth characteristics of a target printer or display device. Line width can be controlled based on various attributes, such as color, size, width, pattern or orientation. Line width can be redefined to be wider, narrower or of a differing color to achieve a desired printed graphic. Also, the method and apparatus can compensate for fill in of reverse-line and “cookie-cutter” holes. The method, performed within a decomposer, examines individual lines of a PDL defined graphic, determines if compensation is needed to achieve a desired printed output, and redefines an operator to achieve the compensation. The compensation can include addition of wider reverse (white) lines under colored lines to prevent the fill in.

摘要： A control system for a xerographic printer utilizing hybrid scavengeless development in the marking process which selectively adjusts process parameters for closed loop feedback control to maintain a preselected tone reproduction curve. The curve is selected to enhance the effectiveness of the range of distinguishable densities in a printing device. The system monitors a series of control patches of varying area coverage density and compares the representative values from the sensor patches with preselected target values. When the measured value significantly departs from the target value, control steps are implemented to affect the toner powder cloud height in the development zone to either add or decrease the mass of toner powder deposited on the photoreceptor.

摘要： A solid area process control for scavengeless development using a transport roll-to-donor roll DC bias as a control parameter in an electrophotographic printing machine is disclosed. The process develops a latent image of a solid area toner patch on a photoconductive belt. Once the patch is developed, the patch is measured with an infrared reflectance type sensor. The measured development mass is compared to a target value stored in the machine memory. A test of the comparison is performed by the process. If the result of the test is less than the target value, the transport roll-to-donor roll bias is increased and the process ends. If the result is more than the target value, the transport roll-to-donor roll bias is decreased and the process ends, otherwise the process stops because the measured development is acceptable. The process is run at predetermined intervals to maintain constant output from the electrophotographic printing machine.

摘要： Haptic security features, which are generally not visually perceptible or reproducible, are applied on a surface of a substrate according to a predetermined scheme. The haptic security features are complemented by visual features that bear a relationship to the haptic security features, and/or otherwise to features of an underlying image that is already printed on the substrate. One or more colored ink layers that includes characters or other features that bear a relationship to the haptic security features is embedded into the haptic security features on the surface of the substrate to form a composite security feature that has visual information as well as haptic response. Haptic security features are based on redundantly encoding features that are pre-printed on the substrate in a preliminary step of forming a visual image on the substrate by overprinting portions of the underlying pre-printed image related to the haptic security features.
