Abstract: To avoid the image artifacts of a uniform drop-per-pixel, a drop assignment overlap is introduced. Larger and lower drops are printed simultaneously to represent uniform gray level. The regions at which the first number of drops and the second number of drops are put down overlap. Thus, a pattern in which a uniform number of drops is put down at every pixel is eliminated, and a pattern of overlapping first and second drops is obtained.

Abstract: This invention relates to a method and apparatus for processing images having color combinations. Such combinations may be embodied in, for example, a black object being printed within a color object or in a black object that includes drops of process color within the object. In these circumstances, undesired image artifacts and halos are eliminated in images that include black portions that are adjacent color portions, and/or improved printed edges are created, by offsetting the corresponding black pixels relative to the color pixels and etching preselected pixels from the image before printing.

Abstract: A system and method for detecting edge locations where intercolor bleeding would likely be a problem, and reducing the amount of ink printed at those locations. The method operates on image data including a set of pixels with each pixel having multiple separation values. Upon receipt of the image data, the data is analyzed to identify those pixels located at an edge. A coverage value is computed from the separation values for those pixels identified as being located at an edge. Based on the coverage value, a reduction factor is determined. The reduction factor is used to multiply the separation values for the pixels located at the edge to yield reduced pixel values.

Abstract: A method for improving security with a printer and sensitive hardcopy output. The method comprises examining incoming print jobs for indication of sensitivity and need for increased security. Any such identified job when printed is monitored. This monitoring is accomplished by watching a sensor provided on the output bin. When the identified job is removed from the printer a message is sent to the originator of the print job with a time stamp indicating that the hardcopy output has been removed.

Abstract: A method for improving human interaction with a printer and its hardcopy output. The method comprises printing a print job and placing it into an output bin followed with a pause before printing a banner page for that print job. However, this banner will not be printed if the print job is removed from the output bin before the pause concludes and thereby expedite any subsequent printing output that may follow. This allows the individual to pick up their print job immediately with out accruing the expense or waste of printing a banner sheet.

Abstract: An image forming system and an associated method for correcting ink droplet placement errors across a printhead. By creating an ink droplet characterization of the printhead, the image forming system is able to time the firing of printhead ink ejectors to avoid drop placement errors caused by ink ejector velocity variations or printhead alignment errors.

Abstract: A method is provided for rendering a color image with a plurality of separations with a halftone process using a single screen. The screen is comprised of a plurality of pixel locations with associated threshold values and the image is comprised of a plurality of separation values. The method includes the steps of rendering a first one of the plurality of separations in accordance with the screen, wherein the plurality of pixel locations are turned on or off at a given pixel location based on a comparison of the image separation value at that pixel with the screen threshold value. The rendering of the next color separation is made in accordance with the rendering of the first separation and the screen, wherein for constant image separation values, pixel locations are turned on for the separation at pixel locations disposed in a highest available luminance region having a lowest available threshold value. When successive filling approaches the end portion of available threshold values, overlap filling with earlier rendered color separations occurs before the screen is completely filled.

Abstract: A method for printing in an image forming system is disclosed. The method, in combination with an apparatus printhead, suppresses defects in printed images. When an image forming system prints an image or group of images in a swath by swath manner, there is a tendency for minor printing defects to arise based on poor alignment of the printhead or ink ejectors, or an error in the instruction software. The printing defects can be defects such as unwanted white spaces or lines, or unwanted bold areas or overlapping swath edges. The present invention utilizes the edges of the swaths to insert a stitch line between the swaths having a different number and size of pixels printed, to allow for modification of the stitch line after measuring an actual advance of a printing medium between each instance of a swath. The same image data line provides the instructions to print both the first and second portions of the stitch line, between each swath.

Abstract: Method and apparatus for controlling consumable use in an image-rendering device. More particularly, the invention relates to a image-rendering device that facilitates the limitation of page costs of color documents by establishing a threshold cost limitation and controlling one or more colorant amounts to be used on the page to ensure that the cost limitation is met. An optional override mode may be provided, wherein a selected page or pages, or a complete document, would be rendered without implementation of the cost reduction feature.
