Embodiment 1
[0057] Next, Example 1 according to the above-mentioned embodiment will be described. This example is an explanation of the case where the ink of Colorgrafx Supplies X2 Ink of Zelox Engineering Systems Co., Ltd. and the recording medium of Colorgrafx X2 Paper, Presentation, 360 of the company are used.
[0058] The ink set for an image recording device of this embodiment is composed of six colors of cyan, light cyan, magenta, light magenta, yellow, and black. The inks of the blue-green series and the purple-red series have normal inks (cyan ink (26R678), purple ink (26R679)) and light inks (light blue-green ink (26R681), light purple ink ( 26R682)). The concentration of each light ink is lower than that of the normal ink of the same color.
[0059] Light cyan ink (26R681) is a so-called light cyan ink (diluted ink) made by diluting cyan ink (26R678) with a solvent. Similarly, the light magenta ink (26R682) is a so-called light magenta ink (diluted ink) made by diluting the ...
Embodiment 2
[0074] Next, an ink unit for an image recording apparatus according to Example 2 of the above-mentioned embodiment will be described. In the second embodiment, the same members as those in the image recording device ink device of the first embodiment are denoted by the same reference symbols as those in the image recording device ink device of the first embodiment, and their detailed descriptions are omitted.
[0075] This embodiment is also the same as Embodiment 1, and is also an explanation of the following case, that is, the ink of the Colorgrafx Supplies X2 Ink of the company and the recording medium of the company's Colorgrafx X2 Paper, Presentation, 360 are used. Case.
[0076] The occasion described in this embodiment is such that when the gray scale of magenta with 256 tones is recorded, magenta ink (normal ink) starts to be used when the tonal level reaches 166 tones, that is, the present embodiment is The case of an inkjet printer in which the printing start level ...

Abstract
The present invention provides an ink set for an image recording device, which includes a first ink and a second ink that is the same color as the first ink and has a different concentration. The second ink has a hue close to that of the first ink and is mixed with a colorant of a color different from that of the first ink.
Description
technical field [0001] The present invention relates to an ink set for an image recording device having a plurality of inks for recording an image on a recording medium. Background technique [0002] Known image recording devices come in various styles. In recent years, an ink-jet printer employing an ink-jet recording method has been widely used in consideration of factors such as relatively cheap and compact structure. Such an inkjet printer ejects ink droplets toward a recording medium to record an image on the recording medium. [0003] In the above-mentioned inkjet printers, various recording methods are used in order to add shading to recorded colors. One recording method is to increase or decrease the number of dots per unit area of ink dots ejected onto a recording medium. When recording the gray scale (gray scale) by this recording method, parts with low tone levels are recorded at a lower printing ratio, and parts with higher tone levels are recorded at a high...
