摘要： The present invention is designed to make uniform frequencies with which individual recording elements of a multihead are used in a recording apparatus for performing gray scale recording by controlling a number of dots recorded in a unit area. A gray scale pattern used to display gray scale is a pattern in which a plurality of blocks each comprising a dot concentration type gray scale pattern having a size smaller than that of the gray scale pattern is dispersed. The maximum difference between numbers of times the recording elements in the range of the gray scale pattern are used can be restricted within twice, and individual nozzles can be used uniformly. Consequently, imbalance of changes in the recording elements with time, caused by the differences between the frequencies with which the recording elements are used, can be restricted, thus restricting irregularities on an image.

摘要： When a black image region is printed, the overall pixels in the region is printed by a black ink. Then, a cation type cyan ink which makes a coloring agent in the ink insoluble is printed on the pixels of a predetermined pattern. By this, the dye of the black ink is maintained near the surface of the printing medium to increase density of the black image. At the same time, for preventing variation of tone of the black image, the pixels of the predetermined pattern are printed by a yellow ink.

摘要： Disclosed is a color ink jet recording method including the step of recording a desired color image on a recording medium on the basis of recording data using a black ink and a plurality of color inks each being different from the black ink in permeating characteristics against the recording medium. In this method, the surface tension is 40 dyn/cm or less for each of the inks; and the blotting factor against plain paper is 2.5 or less for the black ink, and it is in the range of from 2.5 to 3.5 for each of the color inks. Alternatively, the surface tension is 40 dyn/cm or less for each of the inks; and the permeating rate against plain paper is one second or more for the black ink, and it is less than one second for each of the color inks.

摘要： An in ink jet printing method and apparatus are disclosed which prevents mixing of ink with a liquid insolubilizing and/or agglomerating the ink and which can print images having excellent water resistance and high quality. Prevention of mixing of the ink with the liquid is achieved by separately arranging an ink receiver for receiving ink ejected by preliminary ejection and the liquid insolubilizing and/or agglomerating the ink ejected by preliminary ejection, or by setting the distance between the ink jet cartridge for the liquid and the cartridge for ink adjacent thereto is made larger than the distance between two adjacent ink jet cartridges. Alternatively, the direction of ejecting ports of an ink jet ejectors may be deviated. Prevention of mixing may also be achieved by using in addition to printing head ejecting ink onto a printing material, a printability improving liquid ejecting head ejecting a printability improving liquid which insolubilizes and/or agglomerates the coloring material in the ink, and recovering units for recovering the heads. Also, mixing of the ink with the liquid is prevented upon capping, wiping, suction recovering.

摘要： An ink-jet recording apparatus ejects droplets of a recording-improvement liquid on a boundary line between two different color portions of an image by using an ink-jet recording head. The ink-jet recording head comprises a group of nozzles for ejecting the recording-improvement liquid which is responsible for precipitating or condensing a coloring substance in the ink. Accordingly, a high-quality image that comprises black-color portion with a high image density without causing any feathering and multiple-color portions without a spread of ink can be obtained.
