摘要： An embodiment of a printing system is provided with an inkjet printhead having plural portions each having an ink-ejecting nozzle. The printing system includes plural heater elements each associated with one of the plural portions to pre-warm ink dispensed by the nozzle of the associated portion in response to a pre-warming signal. The printing system also includes a controller configured to generate the pre-warming signal for one or more heater elements based on a selection criteria for generating the pre-warming signal only when the nozzle of said associated portion is required to eject ink during an upcoming print swath.

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.
摘要翻译：在本发明的一个实施例中，对于双程打印模式，代替两次或更多次彩色打印头每次通过沉积相同量的墨水，在预定方向上的一个通过（主通道）沉积了绝大多数的墨水和其他通行证（二次通行证）沉积剩余的墨水。至少在打印相同颜色的相邻条纹时，特定复合颜色的主要通行必须始终处于相同的方向以最小化色彩偏移。为了最小化颜色偏移，主通道的方向的选择可以是任意的，与性能相关，或者与滑架中的原色的顺序有关。这种大多数墨水通过将主导墨水效果，并导致颜色偏移不太明显。每次通过的墨水量可以在经验基础上确定。这种在预定方向的通过期间放置更多墨点的技术适用于任何数量的通过，但是特别适用于双程打印模式。

摘要： A method of producing and using photo media to print a glossy, photo-quality image. The image is printed onto the back of a coated transparent base. Thereafter, an opaque backing is applied to cover the printed image. The resulting print is viewed from the front, which provides the photo-quality, attractive appearance primarily because of the substantial gloss depth and uniformity attributable to the transparent base. The transparent base and backing protect the ink-receiving coating and make the resulting print very durable. The image is light fast because the ink is sandwiched between the transparent base and the backing, thereby sealing the ink from oxygen. In a preferred embodiment of the present invention, the backing is applied as a liquid using substantially the same mechanism as used for printing the image.

摘要： A computerized method for improving ink-jet print quality. A jittered print mode is instigated to scatter print errors having a cyclic cause, viz., patterns of visibly noticeable artifacts or dot arrangements caused by mechanical misalignments and vibrations and electrical tolerance variations that are cyclic in nature. A jitter of ink droplet firing time is intentionally introduced whereby printed dot placement is offset less than a dot diameter. The jitter algorithm is adaptable to a variety of implementation schemes.

摘要： Disclosed herein is a motion monitoring system for monitoring movement of a brush-type DC motor. The system includes an electrical comparator having first and second differential inputs. A current detector is connected to provide a drive current signal to the first differential input of the comparator. A low-pass filter is connected to provide an averaged drive current signal to the second differential input of the comparator. When a drive current is applied to the motor, the comparator produces a stream of binary logic-level pulses corresponding to motor movement. The pulses can be used to determine motor position and velocity.

摘要： A halftoning method and apparatus reduces the occurrence of unaesthetic color print output associated with the different relationships found in the numeric data contained within the color data planes. The calculation, modification and distribution of error values, resulting from the mismatch between color plane values and firing thresholds, are performed in a manner that minimizes unaesthetic conditions. Error values are modified by use of error modification functions, bitmaps and matrixes. Firing decisions are based on a comparison of the modified error.

摘要： The present invention provides a method for compensating for the velocity variation in an ink-jet pen by dynamically varying the ink drop firing timing as a function of pen velocity. This makes it possible to print while the pen is accelerating or decelerating without affecting image quality. Scanning velocity change compensation is dynamically and continuously updated at a rate equal to or greater than an encoder edge rate. Further, the present invention provides a method for improving ink drop positioning accuracy across a print media scan by compensating for the change in ink-drop flight time as printhead-to-paper distance changes. Ink drop flight time error is dynamically compensated such that a fired droplet of ink hits its intended target pixel without any appreciable error.

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.
