The ink set of this invention comprises an anionic black pigmented ink and at least one color ink containing a dye or pigment colorant. The performance of these ink sets is improved by the addition of specific cationic surfactant or cationic (quaternary) salts which interact with the anionic black pigmented ink to provide improved black to color bleed control.

An inkjet recording method which suppresses feathering and color bleeding and is excellent in fixability to a recording medium. The inkjet recording method includes the steps of applying an ink-receiving solution prepared by dissolving in an aqueous solvent at least one metal salt having a water solubility of 0.1 mol/l or more, selected from calcium salts, magnesium salts, nickel salts and zinc salts having a valence of 2 or more, to at least the surface to be printed by using an inkjet ink or the entire surface of a recording medium; and printing on the metal salt adhered part by using the inkjet ink comprising at least a pigment, a resin emulsion and an aqueous solvent containing a surfactant. Further, a phosphorus-containing group having at least one P—O or P═O bond is bound to the surface of the pigment.

In color ink-jet recording, even if a black image is recorded adjacent to a color image, the present invention prevents bleeding between black ink and color ink to achieve a high recording grade. In a divided recording method, as division patterns used to allot image data to each recording scan, different division patterns are provided for black image data and for color image data. The division patterns for black and another color used during the same scan have different allotment rates so that the amount of image data allotted to the same scan varies between black and the other colors. As a result, the amount of image data recorded during the same scan also varies between black and the other colors. This reduces the frequency with which the black ink and the color ink are provided adjacent to each other during the same scan.

Methods are disclosed herein that provide more efficient improved edge trimming of extracted foreground images, eg, without additional user interaction. The edge trimming methods described herein generate relatively continuous transparency (or alpha values) along the boundaries of extracted objects (eg, to limit bleeding and/or artifacts).

An ink-jet recording method includes: determining an aggregation degree G (AB) brought about when the ink A and the ink B are brought in contact with each other, at least one of the ink A and the ink B containing a pigment; judging, based on the aggregation degree G (AB), whether or not a boundary portion PC is to be formed at a boundary between a recording portion PA of the ink A and a recording portion PB of the ink B by using an ink C; forming the recording portion PA; forming the recording portion PB; and forming the boundary portion PC if it is judged that the boundary portion PC is to be formed. In the ink jet recording method, the cost is low, the recording quality of a recorded matter is excellent, and the bleeding can be effectively avoided.

Disclosed are an ink set including a recording composition and a processing composition capable of producing high-quality images without fuzzing or bleeding on plain paper, an image forming method and an image forming apparatus using the same, and printed matter. The image can be formed by applying a recording composition containing a colorant and a treatment composition containing a component active to the colorant such that they are contacted and mixed on the recording medium, and adjusting the pH of the mixture. In imaging, this component has an isoelectric point where the zeta potential according to the pH change of the mixture is zero, and the recording composition is adjusted such that the change in the more acidic side from pH (c) depends on the pH change of the mixture When ζ is -2.5mV·l/mol, pH(c) satisfies a<γ and a<c.

The invention discloses a water-based multicolor paint which comprises a protective glue, a base paint and a continuous phase, wherein the weight ratio of the protective glue to the base paint to thecontinuous phase is (5-15): (25-35): (7-13). The water-based multicolor paint prepared by the invention is placed for a long time after being oscillated, and colored particles are free from sedimentation or floating layer phenomenon, and are free from being bonded into clusters and bleeding phenomena. In addition, the water-based multicolor paint has the advantages of stable film, favorable waterresistance and favorable water whitening resistance, and thus, has very high practical application prospects.

The invention provides an ink jet method and an ink jet apparatus, which can improve the color reproduction range and the bleeding balance. The ink jet method includes a step of ejecting a first composition from an ink jet head, the first composition being a radiation-curable composition having a hue angle of -50-degree to -5-degree; a step of ejecting a second composition from an ink jet head, the second composition being a radiation-curable composition having a hue angle of 5-degree to 50-degree; and an exposure step of curing the ejected first composition and the ejected second compositionby exposing the ejected first composition to radiation within 1 second after landing of the ejected first composition and exposing the ejected second composition to radiation within 1 second after landing of the ejected second composition.

The present invention discloses a non-floating-color flat screen printing process. The process comprises the following steps of firstly, performing color separation and sketch drafting according to the colors of a fabric and a pattern, printing the pattern on the fabric through a printing machine, feeding the fabric into a pre-drying machine for drying, then feeding the fabric into a steaming boxfor steaming treatment, putting the steamed fabric into a water tank for water washing and color fixing, and finally performing heat setting. According to different dye types and ratios in printing and the size of the printed pattern, a cleaning agent and a color fixing agent are used in a targeted manner in the water washing and color fixing process, and according to the printed color and patterneffect, different action temperatures and time are selected in the washing and color fixing process, so that the cleaning effect is improved, various fastnesses are improved, the floating color is reduced, the produced fabric is clear in pattern and fine in line, the floating color does not exist on the surface of the fabric, and color bleeding, diffusion and transfer are not generated during storage or use.
