The jet ink comprises a cyan ink, a fuchsin ink and a yellow ink; simultaneously, the ink contains a penetrant, a humectant, a surfactant and a color sizing; the color sizing of the cyan ink comprises pigment blue C.I.P.B. 15:3; the color sizing of the fuchsin ink comprises pigment purple C.I.P.V. 19; the color sizing of the yellow ink comprises at least one of pigment yellow C.I.P.Y. 151, pigment yellow C.I.P.Y. 155 and pigment yellow C.I.P.Y. 180. The jet ink hasthe advantages that: through the careful selection of the pigment for a jet ink set, a set of the jet inks for ink-jet printing is prepared,; and through testing, the jet ink set has larger color expression range, particularly has better color reducing capacity on green, yellow and red and increases the bulking value of the color range of the jet ink set.

Description

One group of pigment-type ink-jet ink with bigger color expression range

(1) technical field:

The present invention relates to one group of jetting ink, particularly one group of pigment-type ink-jet ink and compound method thereof with bigger color expression range.

(2) background technology:

Color inkjet printer the earliest is the mixing acquisition colour print effect through green grass or young crops, magenta and yellow ink.Yet because blue or green, the pinkish red and yellow black blackness that blends of three primary colors is not enough, therefore in three color systems, added black ink, constituted four color systems.Present many desktop printer are still used four chromatic inks.Along with color requirement improves constantly to printed colors, the color inkjet printer ink develops and six color systems, promptly in four color systems, adds nattierblue and light magenta.In order to export better gray level image, in 6 chromatic ink systems, added light black and light black, constituted 8 chromatic ink systems.

No matter the ink system of how many colors is all followed the trichromatic mixing principle of printing.

100% green grass or young crops+100% magenta=indigo plant

100% magenta+100% Huang=red

100% green grass or young crops+100% Huang=green

100% green grass or young crops+100% magenta+100% Huang=black

Difference along with their stack ratios then produces distinct colors.

The universal method of describing color is to overlap the technological standard that defines with measuring color according to one of the international luminouslighting council (CIE) foundation.CIE is according to human-eye visual characteristic, and a cover that converts wavelength of light into brightness and form and aspect is described color data, and wherein L represents the brightness of color, and the red partially green partially degree of color is described in a representative, and b then represents the yellow partially blue partially degree of color of describing.In the CIE color space, each human eye visible color all has a position that belongs to this color.It is thus clear that the photodistributed color space represented color space that is exactly CIE.The color space that is produced by screen or printshop is all within the containing of CIE color space.Therefore all can note its color expression range during the exploitation of screen or printing-ink, and through constantly three primary colors being revised to obtain maximum color expression range.

For ink-jet printer, the employed pigment combinations of ink-jet ink sets is the direct factor that influences this ink group color expression range.Therefore can reach the purpose that enlarges color expression range through the combination of selecting green pigment, magenta pigment and yellow ultramarine.

The color expression range of a stamping machine is described; Can let stamping machine close some color table of printing under the pattern of color management; The color lump that contains variety of colors in these color tables; With the CIELab value of these color lumps of spectrometer measurement, re-use software these numerical value are handled then, just can obtain the color expression range of stamping machine.The color table that generally is used for the test of stamping machine color expression range has ECI2002, TC9.18 and IT8/7.3 etc.

Chinese patent 200680011772.9 contains high-density and low density xanchromatic photo inkjet ink group; A kind of ink group of mentioning at least four kinds of colors comprises high density cyan, low density cyan; High-density magenta, low density magenta, comprise the high-density (concentration) of Pigment Yellow 73 74 yellow with low density (concentration) yellow that comprises Pigment Yellow 73 155.Chinese patent 200680011772.9 has been studied the yellow ink that uses two kinds of different densities and has been satisfied simultaneously to obtain maximum fade resistance and brighter image; But do not study the effect of the pigment combinations printer color expression range of different form and aspect, and use the yellow ink of two kinds of different densities (concentration) in implementation process, to be not easy to realize.

It is a kind of except realizing photostabilization and the water tolerance, can also realizing preferable image, the particularly combined ink liquid for ink jet recording of the image of good form and aspect that Chinese patent 200810109167.6 provides.This combined ink liquid for ink jet recording is a kind of combined ink liquid for ink jet recording that cyan ink fluid composition, magenta ink fluid composition and yellow ink fluid composition form that includes; Wherein, Said cyan ink fluid composition contains the pigment Blue 15 from C.I.: 3 and the C.I. pigment Blue 15: at least a pigment of selecting 4 groups that constitute forms as tinting material; Said magenta ink fluid composition contains at least a pigment of from the group that C.I. pigment red 122, C.I. Pigment red 202, C.I. Pigment red 209 and C.I. pigment violet 19 constitute, selecting and forms as tinting material, and said yellow ink fluid composition contains C.I. Pigment Yellow 73 213 and forms.Use patent 200810109167.6 described inventive methods; By the C.I. pigment Blue 15: 3, the ink group that constitutes of C.I. pigment violet 19 and C.I. Pigment Yellow 73 213 can obtain 660,000 gamut volume value, and distance can also have certain gap greater than 700,000 gamut volume value.
