Abstract

The invention provides a printing method combining gravure printing and digital printing of a printing device and a print. The printing method includes the following steps of (1) detail drawing, specifically, a target pattern is decomposed into a gravure printing pattern and a digital printing pattern; (2) gravure printing, specifically, gravure printing is conducted on a material through a gravure printing unit, and the gravure printing pattern is obtained; (3) material detection, specifically, position information of the material is detected through a detecting unit; and (4) digital printing, specifically, according to the detected position information of the material, spray printing is conducted through a digital spray printing unit, the spray printing speed and a spray printing targetpattern are adjusted according to the detected position information of the material, and thus the digital printing pattern is obtained.

Description

technical field [0001] The invention relates to a printing method combined with gravure printing and digital printing using a printing device and a printed matter, belonging to the field of printing and dyeing. Background technique [0002] Digital printing is printing using digital technology. Digital printing technology is a high-tech product that integrates machinery, computer, electronic information technology and gradually formed with the continuous development of computer technology. The emergence and continuous improvement of this technology has brought a new concept to the textile printing and dyeing industry, and its advanced production principles and methods have brought an unprecedented development opportunity for textile printing and dyeing. However, digital printing has the disadvantages of slow speed, small output and high cost, so it is not suitable for mass production. [0003] A gravure printing machine is a machine that uses gravure plates for printing. ...
