摘要： A high quality gray scale (monochrome) image in which influences of “recorded color deviation” and “color transition” are suppressed is formed even in the case of a slightly uneven discharge amount. When a gray scale (monochrome) mode is set, in the entire range of a luminance signal, density signals corresponding to achromatic dots and small chromatic dots respectively are generated based on the luminance signal so that the density signal corresponding to the achromatic dots has a greater value than that of the density signal corresponding to the small chromatic dots. Accordingly, even a slight “recorded color deviation” that occurs when the achromatic dots are recorded can be corrected by the small chromatic dots having a hue opposite to the direction of color deviation, and a high quality gray scale image in which influences of “recorded color deviation” and “color transition” are suppressed can be formed.

摘要： The color of magenta using newly developed magenta ink has characteristics L*≅41, a*≅82, and b*≅24, and has differences ΔL*≅4, Δa*≅0, and Δb*≅26 from the conventional magenta ink, i.e., the lightness value is low, and the color difference b* assumes a very small value. When the color of red is reproduced using such new magenta ink, its lightness and saturation values are low, and subdued red is reproduced, i.e., a visually favorable color cannot be obtained. Hence, when a color included in a first color gamut is input, and the input color is converted into the color of a second color gamut narrower than the first color gamut, color conversion is made using a three-dimensional lookup table having red defined by. L*≅45 to 50, a*≅67 to 70, and b*≅50 to 55.

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： A printing apparatus includes a plurality of inkjet print heads to which humidified air is supplied to retain the humidity in the print heads. Ink colors for the plurality of heads are arranged in a sequence corresponding to ink characteristics. The plurality of print heads are arranged in a sequence such that a print head configured to eject ink characterized by having a larger amount of volatile components evaporated within a predetermined time is located in a more upstream area.

摘要： A process of detecting a defective recording element and a process of correcting the defective recording element are performed with appropriate processing loads. When the detection process and the correction processes are performed with small loads, for example, at a time of recording, a resolution used for reading an inspection pattern is set lower than that set in a case where the processes can be performed with small loads, for example, at down time before recording. The reading resolution to be set may be determined by an apparatus in accordance with a processing load or may be arbitrarily determined by a user.

摘要： A waiting time Ts is decided on the basis of ink type information and ink feed amount information, referring to waiting time table A (Step 6). Along with this, a dried printing paper is carried to and stopped in a waiting area 9 (Step 7), a time period T is measured after stopping, and measurement processing in the next step is delayed until the time period T reaches the waiting time Ts. Then, when the time period T reaches the waiting time Ts, a measuring instrument 10 is used to measure a density of a patch printed on the printing paper (Steps 8 and 9).

In order for this to be achieved, a level is set up to a overlapping portion of a chip of a print head depending on dot impact accuracy, and a print data distribution rate of each chip in the overlapping portion is determined according to the level.
