摘要： Recording in a recording apparatus is controlled according to the temperature of a recording head. The temperature of the recording head and the surrounding temperature around the recording head are detected. An offset value, based on the temperature of the recording head and the surrounding temperature, is set at a predetermined timing. The detected temperature of the recording head is corrected, based on the offset value. The offset value is renewed, based on the head temperature and the surrounding temperature, during repetition of detection of the head temperature.

摘要： Random masks each having a given size and defining a random array of non-record pixel locations and record pixel locations are placed in association with record areas in mask registers. Using the placed masks, record data is thinned-out and supplied to a recording head. An image is then recorded. Thus, since thinning-out masks do not have periodicity, any inherent density nonuniformity loses periodicity. Consequently, high-definition images can be produced.

摘要： An image processing method and an apparatus capable of employing the method, which smooth notches on outlines and output an image of high quality having smooth outlines. First, edges to be smoothed are determined, then numbers of consecutive black dots in the horizontal and vertical directions are counted from originating points in the determined edge. Further, dots for correcting an original image are calculated based on the counted numbers of consecutive black dots. Thereby it is possible to perform the high speed smoothing correction efficiently, facilitating production of a high quality printing apparatus for a reasonable price.

摘要： Print codes supplied from a host computer are received and analyzed to generate print data for the individual colors, and the generated print data are stored in print buffers corresponding to the colors. The print data corresponding to yellow ink with high lightness is expressed by binary data, and is printed by one dot per pixel by a single print scan. The print data corresponding to each of the remaining high-density (thick) inks is expressed by multi-valued data having a larger number of bits than the yellow data, and is printed by a plurality of print scans.

摘要： An ink jet recording apparatus, in which thermal energy is applied to ink in accordance with a driving signal applied to a heater to produce a bubble, by which ink is ejected onto a recording material, includes a driver for applying a plurality of driving signals to the heater for one ejection of one ink droplet. The driving signals comprise a first driving signal not ejecting the ink and a second driving signal for ejecting the ink, the second driving signal being applied after a rest period after the first driving signal. The apparatus further includes a controller for changing an amount of ink ejected by changing a length of the rest period and changing the first driving signal. The controller effects its changing operation in a first changing region in which the rest period is changed without changing the first driving signal and in a second changing region in which a length of the first drive signal is changed.

摘要： An image is recorded on a recording medium by recording dots of a black ink and a color ink discharged onto the recording medium from a recording head. A boundary proximity-degree detecting circuit detects the degree of positional proximity, i.e., closeness, between the recording dots of the black ink and the recording dots of the color ink at the boundary between these dots. A dot substituting circuit performs, in accordance with the detected degree of positional proximity, substitution of the black pixels with recording dots of a color ink at the boundary. Thus, pixels of the image to be recorded are replaced with recording dots of a color ink by an extent which is determined based on the degree of positional proximity between the pixels of the different colors. A sharp black image can be obtained with minimized color mixing at the boundary between the black image region and the color region, regardless of the degree of positional proximity between these regions.

摘要： In the case of printing in three-value level utilizing two kinds of inks mutually different densities for one color (higher and lower density inks), it is assumed that a reflection density of a region having a predetermined area when solid print is performed only by the lower density ink, and that when solid print is performed only by the higher density ink are expressed ODt and ODn, respectively. Since the granular appearance of the ink dots is expressed in terms of reflection density of one dot, the granular appearance of a lower density ink dot at a portion of image formed only by the lower density ink dots and the granular appearance of a higher density ink dot at a portion of image formed by the higher and lower density ink dots are expressed in terms of values of ODt and (ODn-ODt) divided by the number of pixels included in the above region, respectively. Accordingly, by making the reflection density ODt to be approximately one half of the reflection density ODn, the granular appearance produced by the lower density ink dot at the highlighted portion and the granular appearance produced by the higher density ink dot at the portion where the higher density ink dots scattered in the lower density ink dots can be made substantially equal to each other. For this purpose, it is preferable that a dye concentration of the lower density ink is to be about one fourth of that of the higher density ink.

摘要翻译： 在使用两种不同浓度的油墨（高浓度和低浓度油墨）的三值油墨印刷的情况下，假设仅在实施印刷时由具有预定区域的区域的反射浓度 较低密度的墨水以及仅通过较高密度墨水进行固体印刷时分别表示为ODt和ODn。 由于墨点的粒状外观以一点的反射密度表示，所以在仅由较低密度墨点形成的图像部分处的较低密度墨点的粒状外观和较高密度墨水的粒状外观 通过高密度和低密度墨点形成的图像的一部分，以ODt和（ODn-ODt）的值分别除以上述区域中包括的像素数来表示。 因此，通过使反射密度ODt为反射密度ODn的大约一半，由突出部分的低密度墨点产生的粒状外观和高密度墨点在较高密度墨点处产生的粒状外观 可以将分散在较低密度墨点中的密度墨点基本上彼此相等。 为此，较低浓度油墨的染料浓度优选为较高浓度油墨的浓度的约四分之一。
