摘要： An ink jet recording apparatus performs recording by supplying heat energy according to driving pulses to an ink to form a bubble based on film boiling, and ejecting the ink from a recording head onto a recording medium on the basis of formation of the bubble. The apparatus includes a driver and a driving pulse controller. The driver supplies the driving pulses, comprised of a plurality of pulses including a main pulse for causing the ink to be ejected, to the recording head for each ejection of the ink. The driving pulse controller controls an amount of the ink to be ejected, by changing a waveform of the driving pulses supplied by the driver during a recording operation. The driving pulse controller limits energy of the main pulse in accordance with a start timing of the film boiling which is variable according to a change in waveform of pulses other than the main pulse.

摘要： According to this invention, upon execution of recording by ejecting an ink droplet from a recording head, a surrounding temperature sensor for measuring the surrounding temperature is provided to a main body side, and a change in temperature of the head is presumed from the past to the present time by calculation processing, so that optimal temperature control can be performed without arranging a head temperature sensor having a correlation with the head temperature. At this time, the ejection quantity can be stabilized by changing the pulse width of a driving signal on the basis of the presumed head temperature, and ejection can be stabilized by performing restoration processing.

摘要： A liquid jetting device includes a plurality of liquid passages each having a liquid ejecting element and communicating with an ejection hole, a common liquid chamber communicating with each of the plurality of liquid passages and an air bubble introducer for making a non-disappearable air bubble formed by thermal energy exist in the common liquid chamber before a start of liquid ejection. The liquid is allowed to be ejected in the presence of the air bubble. The non-disappearable air bubble functions as a buffer to absorb pressure during discharge to restrict flow of the ink in the direction opposite to the discharge port.

摘要： A paper feed operation is performed by a width less than one pixel (½) in addition to an integer multiple number of pixels (n/2) with respect to a basic number of pixels inherent to an ink jet recording apparatus having a multi nozzle head having n nozzles. When a plurality of pixel recording operations are performed for a single pixel region, ink dots land within a distance less than one pixel unit (½). Thus, a variation in ink surface density on a recording sheet in an overlapping print operation is reduced, thereby efficiently increasing the image density, and preventing blurring by promoting absorption and evaporation of an ink to and from a paper sheet.
摘要翻译：相对于具有多个喷嘴头的喷墨记录装置固有的基本数量的像素，除了整数倍数的像素（n / 2）之外，还进行小于一个像素（1/2）的宽度的进纸操作有n个喷嘴。当对单个像素区域执行多个像素记录操作时，墨点落在小于一个像素单位（½）的距离内。因此，在重叠打印操作中记录纸上的油墨表面密度的变化减小，从而有效地提高图像浓度，并且通过促进油墨向纸张的吸收和蒸发来防止模糊。

摘要： In the process of correcting a color deviation caused by output characteristic variations among different colorants in a printing apparatus, a method of printing a test pattern allows an appropriate and highly accurate visual detection of the color deviation. More specifically, the test pattern has a plurality of patches printed therein, each of which has placed adjacent to each other a test area to be checked for the color deviation and a reference area serving as a criterion for color deviation and which has the test area and the reference area repeated alternately. If the colors of the two areas look different during the comparison of only one pair of the test area and the reference area, the pattern of the two alternately repeated areas makes the colors of the two areas appear more uniform, alleviates a high color difference sensitivity and thereby enables easy identification of a patch that matches the accuracy of the correction performed according to the color deviation detection.
