摘要： In one embodiment of the present invention, for a two-pass print mode, instead of two or more color printheads depositing the same amount of ink for each pass, one of the passes (the primary pass) in a predetermined direction deposits a substantial majority of the ink, and other pass (the secondary pass) deposits the remainder of the ink. The primary pass for a particular composite color must always be in the same direction for minimizing color shift, at least when printing contiguous swaths of the same color. For minimizing color shift, the choice of a direction for the primary pass can be arbitrary, related to performance, or related to the order of the primary colors in the carriage. This majority ink pass will dominate the ink effects and cause color shifts to be less perceptible. The amount of ink per pass may be determined on an empirical basis. This technique of depositing more ink dots during a pass in a predetermined direction applies to any number of passes, but is particularly applicable to two-pass print modes.

摘要： One aspect of the present invention is a color printing system that is responsive to color information for forming images on media. The color printing system includes a determining device that determines colorant usage for a plurality of colorants. The determining device detects a balanced condition wherein colorant usage is within a nominal range and an imbalanced condition wherein colorant usage exceeds the nominal range. The color printing system also includes a colorant balancing device. The colorant balancing device responds to the imbalanced condition for altering colorant usage for compensating for the imbalanced condition.

摘要： The present invention uses various real-time monitoring and resultant data inputs to change the print mode, dynamically during print cycles. Note that as a result of real-time monitoring and print mode adjustment, predetermined primary default print modes can be set a higher performance level. Various feedback subsystems provide real-time information critical to selecting specific print mode operational parameters, or “Operational Attributes.” The attributes allow the print mode to be fine tuned, dynamically, for each printer and pen combination over the life of the printer. Thresholds that signal a print mode change are defined.

摘要： A method of automatically optimizing the controllable parameters related to producing printed material on a hardcopy output device is provided, along with a hardcopy output device configured for implementing this method. Users require different types of printed objects to have different characteristics. Specifically, business graphics need to be sharp and vivid, photographic images should look realistic, and text must be black, crisp and clear. By extracting, analyzing and conditioning data generated during a printing stream, the various regions of text, graphics and photographic images on a sheet are distinguished, characterized, and printed. The resulting hardcopy output has a custom balancing of color which is pleasing to the human eye for each type of image printed, and which has print characteristics tailored for the specific elements on the page.

摘要： A method of reducing pixel density in pixel array printers, alternatively termed depletion, uses information about a pixel when it is first available instead of having to recalculate that information at a later time. According to embodiments of the present invention, the process of identifying edge pixels for the purpose of depletion is performed during a halftoning process, in which every pixel in a pixel data array is examined. Pixels are classified as one of four possible pixel states: a blank pixel, a left/right edge pixel, a top/bottom edge pixel, or an area-fill pixel. The pixel state information is stored in a modified pixel data area. A predetermined pattern of filled and unfilled smaller pixels is identified with each pixel state. Each element in the modified pixel data array is mapped onto the smaller pixels according to the predetermined pattern and a printer is controlled according to the resulting pattern.
