摘要： A method is taught for curtain coating a liquid composition onto a moving web at a coating point where the moving web is supported on a backing roller. The web is partially wrapped around the backing roller, the backing roller including a relief patterned area on the surface thereof, the relief patterned area including relieved features and non-relieved features, the relieved features and the non-relieved features creating an electrostatic force difference exerted on the liquid composition at the coating point when an electrostatic field is applied thereto. A web speed is specified and the electrostatic force difference exerted on the liquid composition at the coating point is varied to determine a maximum electrostatic force difference for the specified web speed that achieves the predetermined acceptable level of coating thickness non-uniformity. The web is moved at the specified web speed and an operating electrostatic force difference is generated at the coating point that is not greater than the maximum electrostatic force difference for the specified web speed.

摘要： A method is provided for reducing image artifacts in printers that employ two or more printhead nozzle banks that must be aligned and registered with respect to each other either through adjustment of orientation and/or position of one nozzle bank relative to another or through selective control of actuation. In the method, discrete dots are printed by the nozzle banks upon a target receiver medium. Examination of the receiver medium or a reproduction thereof is made by a scanner and information regarding location of the dots is generated. From information regarding location of the dots a determination is made of error placement of the dots from ideal locations. Alignment of the nozzle banks are made in accordance with any errors determined in placement.

摘要： Dies are disclosed for forming sheet-like extrudate of fluent material, such as a film of thermoplastic or solvent-plasticized material, or a liquid coating, e.g. a photographic coating, on a continuous support web. The dies include inner and outer cavities with the fluent material being supplied to the center or an end of the inner cavity. Between the inner and outer cavities there is an inner slot and between the outer cavity and the exterior of the die there is an outer slot. The inner cavity is open at one end, if end fed, or at both ends, if center fed. The open end, or each open end, is closed by closing means which are detachable for allowing access to the inner cavity for cleaning and inspection. A member is located in the cavity extending from the open end or each open end. The member serves to reduce the effective flow path for fluent material in the inner cavity. By appropriate selection of the shape of the member, uniform flow rates of fluent material through portions of the inner slot adjacent the member may be achieved. By providing a plurality of interchangeable differently shaped members, a plurality of different combinations of rheologies and flow rates of fluent material may be extruded while maintaining uniformity of widthwise thickness uniformity of the extrudate. The invention is also applicable in embodiments in which there is only a single cavity and a single slot.

摘要： A computer program product is provided for optimizing a printer for driver settings and color profile in order to optimally print an image on a selected media. Data is stored in an index file for various combinations of printers, printer drivers, printer media and color profiles. The printer driver that is currently used on the user's machine for the selected printer is determined and the printer media selected for the printer is identified, e.g., by a simple query of the user. One set of steps involves choosing an appropriate stored color profile for the selected printer-media combination, and applying the chosen color profile to the image data, thereby generating transformed image data. Another set of steps involves retrieving printer settings for the selected printer-media combination and modifying the settings of the driver in use for the selected media. Finally the transformed image data is printed using the modified settings of the printer driver to obtain optimal printing of the image.
