Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Step 1. Input the printing pattern into the computer, and analyze the ink color sequence. According to the result of the color sequence analysis, the color sequence is set to N types (N≥2), and the N types of inks are respectively added to the corresponding N printing units. One printing machine corresponds to one printing ink;

[0022] Step 2. In the first printing machine, print the base color layer on the transparent film, then dry it through the drying equipment, and then pass through N-1 printing machines in turn, and print on the transparent film in sequence according to the resolved printing color sequence On...

Abstract

The invention discloses a printing turnover device and a printing method. The printing method includes a first step of inputting a printing pattern into a computer to perform ink color sequence analysis, setting the color sequence to be N (N> / =2) according to the color sequence analysis result, and adding N kinds of ink to corresponding N printing machines, respectively; a second step of in the first printing machine, printing an underpainting layer on a transparent thin film, then drying by a drying device, subsequently, through the N-1 printing machines, performing printing sequentially according to the analyzed printing color sequence on the same side of the transparent thin film, and finally covering an ink printing layer with a varnish protective layer; and a third step of after the completion of covering the transparent thin film with the varnish protective layer on one side in the second step, turning over the transparent thin film through the turnover device, performing printing on the other side of the transparent thin film, and after repeating the first and second steps, outputting a printed transparent thin film. The transparent thin film printed by the method has a clear pattern, small ink color difference and high product printing precision.

Description

technical field [0001] The invention relates to a gravure double-sided printing method for a transparent film, in particular to a method for realizing double-sided synchronous printing effects by printing on one side and then by turning over a mechanism. Background technique [0002] With the continuous development of printing technology, digital printing technology is also becoming more and more mature, while gravure printing technology adopts a one-line technology that directly transmits, processes and prints data, and inputs all the data to be printed into the control system. System-controlled printing, like the commonly used digital printing technology of on-demand inkjet printing, under the control of the control system, when the surface of the substrate reaches the designated position, the piezoelectric crystal in the nozzle generates a pulse to squeeze out the ink, and directly Spray imaging to the surface of the substrate. The color of the printed matter is printed b...
