Description
Technical Field
The invention relates to the technical field of printing devices, in particular to a printing device with brighter printing color.
Background
The printing device is used for printing paper to change the paper from blank to color. Under the same conditions of paper and ink, the gloss of the finished product after printing is often greatly different due to the problems in the operation process. Proper auxiliary agents are added into the ink, so that the printability of the ink can be adjusted, and the printing is facilitated. Most adjuvants adversely affect the gloss of the finished product. For example: the main raw material of the anti-sticking agent is the corn flour, after the ink is added, the surface of the imprinting film layer becomes rough due to the precipitation of the corn flour, and the finished product has poor glossiness. And if the six-color thin varnish is added, the fluidity is increased, the permeability of the print on the paper is increased, the dryness is reduced, and the gloss of the print is not favorable. Therefore, the amount of the adjuvant added to the ink should not exceed 5%, and the adjuvant should be kept small or not in consideration of the gloss effect.
But the fluorocarbon surfactant is different from the brightening paste, and the fluorocarbon surfactant can prevent the surface defects of orange peel, wrinkling and the like of the ink layer and can improve the luster of the surface of the printed product. The gloss paste is processed from raw materials with high glossiness, and can increase the glossiness of the printing ink. However, the amount of the two is not suitable to be too large, otherwise, the drying speed of the ink is reduced, the phenomena of dirt sticking and wire drawing occur, and the glossiness is influenced.
Therefore, if the drying speed of the ink can be increased, the fluorocarbon surfactant and the brightening paste can be fully utilized to greatly improve the luster of the surface of the printed product, and the brighter printing color can be realized.
