Problems solved by technology
[0003] Compared with traditional printing, the ink used by digital printing equipment has low viscosity and low pigment content. The problem is that the color saturation is not enough. Due to the low viscosity of the printed font, the diffusion speed is faster. Compared with traditional printing, poor edge sharpness

Abstract
The invention discloses an ink for improving the sharpness of a digital printing edge, and belongs to the technical field of printing. The ink comprises the following components by ratio: 1-10% of a pigment by weight, 5-45% of a solvent by weight, 0.01-1% of a surfactant by weight, 0.1-1% of a pH regulator by weight, 1-10% of macromolecular substance for increasing brightness by weight, 0.01-0.5%of a preservative by weight, 0.01-1% of electrolyte by weight, and the balance of deionized water. The ink is mainly applied to digital printing paper and offset paper, the edge of a line of a typeface of a printed image is smoother and neater, and the burr phenomenon of the edge brought about by the uneven paper is avoided.
Description
technical field [0001] The invention relates to an ink for improving the edge sharpness of digital printing, which can be printed on ordinary paper, digital paper and offset paper to ensure sufficiently high color saturation and control the edge to be sharp enough and clear without burrs; it belongs to the field of printing technology. Background technique [0002] With the rapid development of inkjet technology, the printing speed is getting faster and faster. At the same time, the environmental protection problems of the traditional printing industry are becoming more and more serious. More traditional printing is replaced by digital printing. [0003] Compared with traditional printing, the ink used by digital printing equipment has low viscosity and low pigment content. The problem is that the color saturation is not enough. Due to the low viscosity of the printed font, the diffusion speed is faster. Compared with traditional printing, Edge sharpness is poor. [0004] T...
