摘要： An ink-jet printing method for obtaining higher quality printed Images by utilizing an ink-jet recording technology using a pigment ink and a treatment liquid. A treatment liquid for unstabilizing the dispersed condition of the pigment in the aqueous medium is applied onto the printing medium, and subsequently either an ink containing a self-dispersion type pigment and a pigment dispersed by a polymeric dispersant or an ink containing a self-dispersion type pigment and an ink containing a pigment dispersed by a polymeric dispersant are applied together to the printing medium in such a way that the treatment liquid and the inks are mixed in a liquid state on the printing medium to make the pigments indissoluble.

摘要： An ink jet printing apparatus and an ink jet printing method, whereby high-permeation ink and low-permeation ink are employed to prevent a reduction in optical density is provided. The ink jet printing apparatus controls ejection of ink from print heads, so that only low-permeation ink is ejected onto the edge area of a print medium that is adjacent to a non-printing area, and this time, high-permeation ink is not employed. Further, the ink jet printing apparatus controls ejection of ink from the print heads, so that both low-permeation ink and high-permeation ink are employed for the non-edge area that is adjacent to the edge area, and to perform printing, the low-permeation ink is ejected onto the non-edge area prior to the high-permeation ink.

摘要： An image processing apparatus includes an acquisition unit, a determination unit, and a thinning unit. The acquisition unit may acquire color information concerning color of an image having an attribute of at least one of character or line drawing. The determination unit may determine a thinning ratio for thinning data of non-edge portions of the image according to the color information acquired by the acquisition unit. The thinning unit may thin data of the non-edge portions according to the thinning ratio determined by the determination unit. The thinning ratio determined by the determination unit when the color information indicates a color other than black is lower than the thinning ratio determined when the color information indicates black.

摘要： In a multipass printing that performs a plurality of printing scans over a unit area of a print medium by using a leading head and a follower head, the multivalued image data for the leading head is distributed according to the print volume information for up to the preceding printing scan. Then, the multivalued image data for the leading head is subjected to the grayscale level reduction operation to generate binary data. Based on the binary data, the print volume information is updated, after which the multivalued image data for the follower head is distributed according to the print volume information. This causes a plurality of printing scans or a plurality of print heads, that print the same unit area, to have a correlation among them, with the result that dots on a plurality of planes when overlapped have an excellent scattering characteristic.

摘要： An image forming apparatus and an image forming method are provided which can produce an image with high robustness that can keep image impairments from becoming noticeable even when there are printing characteristic variations over a range of positions of the print elements, as in the case of an end deflection phenomenon. This is realized by distributing multilevel grayscale values of individual pixels according to distribution coefficients determined for the individual print elements that print the pixels, allocating the distributed grayscale values to the associated planes, and binarizing the allocated grayscale values in each plane. With this process, the grayscale value distribution factors in each scan of multipass printing can be determined according to the positions of individual print elements on the print head.
