摘要： An ink jet recording method uses black ink and a plurality of inks having different colors, which have ink penetration properties different from that of the black ink. The method includes generating multi-level black recording datum on the basis of a multi-level color recording datum of a discrimination pixel, wherein a ratio of generation of black recording datum is changed in accordance with a multi-level color recording datum of a pixel marginal to the discrimination pixel; and recording a color image on the basis of the multi-level color recording datum and the multi-level black recording datum generated by the generating step.

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： In image recording by discharging plural inks of different characteristics onto a recording medium, recording pixels to be recorded by at least one of the inks of either yellow, magenta or cyan color subjected to pixel expansion are expanded in four direction, then a logic product is calculated between the expanded pixels and the pixels to be recorded with an ink which is black not subjected to pixel expansion, and the recording pixels to be recorded by the ink which is black not subjected to pixel expansion are replaced by the pixels formed by the inks (Y, M, C) subjected to pixel expansion. Thus high-quality image recording is made possible even in case the inks of different properties are brought into mutual contact.

摘要： A recording head having an ejection portion group for ejecting a black ink, and ejection portion groups for ejecting color inks is used. When a black image to be printed by the black ink is present adjacent to a color image to be printed by the color ink, a black image portion adjacent to the color image and a black image portion which is not adjacent to the color image are formed in different scans, thereby obtaining a high-quality image from which ink blurring at a boundary portion between the black and color images is eliminated.

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： 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.
