Description

Color mixing ink supply system and method Technical Field The application relates to the field of shoe material printing, in particular to a color mixing ink supply system and a method. Background The existing digital printing equipment basically adopts CMYK four-color basic ink for ink supply, and can meet most printing requirements, but has narrower color gamut and limited corresponding manuscript reduction degree, and the problems of thinner ink dot distribution, pitting and the like are easy to occur in some combined color and light color parts. In order to widen the color gamut, the existing digital printing equipment generally adopts color-superposed printing, but for textile digital printing, because of the specificity of textile fabrics, it is difficult to adsorb one ink before superposition and adsorption of other colors, so that the expected color-mixing effect cannot be obtained by superposition of multiple inks. Some devices have extra spot color ink channels to realize wider color gamut effect, namely, besides CMYK, if RGBO ink types are added, even more ink types are added, although the color gamut is wider, the ink inventory management is difficult, the spot color ink needs to be replaced for a long time only if the spot color ink is not used more than the basic color, the ink is easy to be idle and easy to expire, and the ink is lack of flowing and precipitation crystallization which damages a spray head and a pipeline when staying in an ink path for a long time.
