Printing device with brighter printing color

Abstract

The invention discloses a printing device capable of achieving brighter printing color and luster. The printing device comprises a printing device body, a drying base and a cover. The printing devicebody is internally provided with an ink cartridge, the drying base is fixed to the lower part of the front side of the printing device body, the cover is located at the upper part of the front side ofthe printing device body, the drying base is provided with a supporting roller, an air inlet chamber, an air outlet, a dustproof plate, a first induced draft fan and a coil heating mechanism, and thecover is provided with a release chamber, and the release chamber communicate with a buffer chamber through and an air guiding hole; and a cooling chamber communicating with the buffer chamber is arranged above the printing device body, the cooling chamber communicates with a low-boiling point inert material box through a cooling tube, and a mixed feeding mechanism is arranged between the low-boiling point inert material box and the ink cartridge. By means of the printing device, the mixed feeding mechanism is used for mixing low-boiling point inert materials with ink with a fluorocarbon surfactant and bright varnish added, heating is carried out to release the low-boiling point inert materials, the printing ink on a printed product is dried in an accelerated manner, and the printing color can be brighter.

Description

technical field [0001] The invention relates to the technical field of printing devices, in particular to a printing device with brighter printing colors. Background technique [0002] The printing unit is used to print the paper, making the paper from blank to colored. Under the same paper and ink conditions, due to problems in the operation process, the gloss of the finished product after printing often varies greatly. Adding appropriate auxiliary agents in the ink can adjust the printability of the ink for smooth printing. Most auxiliaries will have a negative impact on the finished gloss. For example: anti-sticking agent, the main raw material is six grain flour, after adding ink, the surface of the imprinted film layer will become rough due to the precipitation of corn flour, and the gloss of the finished product will be poor. Another example is the addition of No. 6 thin varnish, which not only increases the fluidity, but also increases the permeability of the impri...

Problems solved by technology

However, the amount of the two should not be too large, otherwise the drying speed of the ink will be reduced, and the phenomenon of sticking and drawing will affect the gloss.
