Abstract

The invention discloses a pretreatment inkjet ink for digital printing. The pretreatment inkjet ink is prepared from the following components by weight percentage: 20-40% of white color paste, 2.0-20%of a color improver, 10-35.0% of a viscosity regulator, 0.1-5.0% of a surface tension control agent, 0.1-1% of a bactericide and the balance deionized water. Specifically, the white color paste is prepared by high speed grinding of the following components by weight percentage: 2-30% of a white color developing agent, 1.0-10% of a dispersing agent, 0.1-1.0% of a defoaming agent, 0.1-3.0% of a pHcontrol agent and the balance deionized water. In addition, the invention also discloses a preparation method of the pretreatment inkjet ink, and the method includes the steps of: adding deionized water, the color improver, the viscosity regulator, the surface tension control agent and the bactericide sequentially into the white color paste under a stirring state, performing stirring until all thecomponents are uniformly mixed, and then conducting filtering. The pretreatment inkjet ink is printed on a printing medium before printing with digital printing ink, so that the color and covering power of a printed pattern can be obviously improved.

Description

technical field [0001] The invention relates to a pretreatment inkjet ink for digital printing, in particular to a pretreatment white inkjet ink for digital printing and an application method thereof, belonging to the technical field of inkjet printing. Background technique [0002] In recent years, digital inkjet has been gradually accepted by the market due to its simple production process, low pollution and flexible printing. Especially with the improvement of printing speed of industrial nozzles, the printing industry has gradually adopted digital printing solutions. Digital inkjet printing saves the cost of plate making in traditional printing methods, and its advantages such as flexible printing and fast drawing have become the advantages of competing with traditional printing. [0003] However, due to the strong absorptivity of the printing medium used in the traditional printing process, this directly leads to the rapid penetration of the ink into the medium when the...
