摘要:
Disclosed herein is an image-forming method, comprising performing image formation on the basis of pixel data by using at least a yellow recording agent, a magenta recording agent, and a third recording agent. A color represented on a recording medium by the third recording agent on a color space of CIE-L*a*b* has lightness higher than lightness of a color reproduction region represented on the recording medium by a combination of the yellow recording agent and the magenta recording agent, and has a hue angle in the color reproduction region. A difference in hue angle on the color space between a color represented by the yellow recording agent and a color represented by the magenta recording agent is in a range of 60 to 113°.

摘要:
A recording method includes the steps of ejecting ink onto a recording material on the basis of image data; and ejecting record quality improving liquid to improve a record quality of the ink ejected onto the recording material; wherein one of the ink ejecting step and the liquid ejecting step is carried out after the other; the liquid ejecting step ejects the liquid to a part of an ink-ejection-area on the recording material to provide liquid-ejection-area and non-liquid-ejection-area.
摘要:
In an apparatus to perform printing by ejecting an ink and a printing quality improving liquid for making a coloring agent in the ink insoluble or coagulated, reaction between the printing quality improving liquid and the coloring agent of the ink is certainly caused. Namely, after ejecting the printing quality improving liquid from a head, Bk ink, Y ink, M ink and C ink are ejected through heads within a given period, e.g. 500 msec. By this, the printing quality improving liquid may react with the coloring agent of the ink before penetrating into a printing medium to certainly make the coloring agent insoluble or coagulated.
摘要:
Disclosed herein is an ink-jet recording process for forming an image by applying an ink to a recording medium in accordance with an ink-jet recording system, comprising the steps of:(A) applying an ink containing a coloring material to the recording medium in accordance with the ink-jet recording system; and(B) applying a liquid composition different from the ink to an ink-applying region of the recording medium in accordance with the ink-jet recording system, wherein the liquid composition is applied in an amount less than 50% by volume of the amount of the ink to be applied to the ink-applying area.
