As shown in figure 3, the prints printed by the sherry yellow special color ink are bright in color and bright overall, and the problems of dark color and insufficient saturation of the yellow ink are obviously solved.
In FIG. 4, it is shown from the comparison of the color gamut maps that the color gamut of CMTK is significantly increased in the yellow and orange regions compared to the color gamut of ISO 12647-22013 CMYK.
The comparative data of the ink performance table show that the sherry yellow special ink has consistent printability with the yellow ink in ISO 12647-22013 and can be matched with CMK printing production.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
