摘要:
An image forming method comprises a step of reacting an ink containing a coloring material with a liquid composition containing fine particles reactive to the coloring material on a recording medium, where the reaction between the coloring material and the fine particles occurs in a liquid, the coloring material is adsorbed on the surfaces of the fine particles while keeping the monomolecular state as in the ink, and the fine particles having the coloring material on the surface aggregate each other. This method can provide images of high optical density and high color saturation, with less occurrence of white stripes in the image.

A liquid composition is adapted for use with an anionic ink for forming a high quality image with alleviated bleeding by means of an ink-jet recording system. The liquid composition includes a first cationic substance and a second cationic substance different from said first cationic substance, of which the first cationic substance is provided in the form of micro-particles at least whose surface is cationic.
摘要:
The present invention relates to a liquid composition, an ink set employing the liquid compositions a method for forming a colored area of an image on a recording medium with the ink-set, and an ink-jet recording apparatus employing the ink set are provided, which enables formation of ink-jet record on a plain paper sheet with a broad color reproduction range, uniformity of the color, less stripy unevenness in a solid print part, and high rub-off resistance of the record. The liquid composition is stable in storage, and is ejected stably from the recording head. The liquid composition is used for forming a colored area on a recording medium by application with an anionic or cationic aqueous ink containing a coloring material, and the liquid composition contains fine particles dispersed therein and the surface of the fine particles being electrically charged in a polarity opposite to the aqueous ink.

This invention relates to an ink set which can form a colored area on a recording medium with a broad color reproduction range, excellent uniformity of the colors, with effective prevention of bleeding at the boundary between adjacent different color areas on a recording medium, and high rub-off resistance of the colored area. The ink set has separately an aqueous anionic or cationic ink containing a coloring material, and a liquid composition containing fine particles dispersed therein and electrically charged at the surface in a polarity opposite to the ink. The ink and the liquid composition are adjusted to give, when mixed at a mixing weight ratio of about 1:1, a pH of the liquid mixture to cause aggregation of at least the coloring material.

Image data, or RGB luminance data input from a host computer, is color-converted by LUT into 8-bit CMYK density data for each ink color. The CMYK density data is divided into predetermined regions and, based on a gray scale value for each of the divided regions, ink application volumes are calculated. According to the calculated ink application volumes, the 8-bit processing liquid application data S is generated. Then, the CMYK density data and the processing liquid application data undergo output gamma processing, after which they are quantized by a quantization processing unit into 1-bit ejection data for each nozzle.
