Printing method and printing mechanism for simultaneous digital jet printing and rotary screen printing

Abstract

The invention relates to a digital jet printing and rotary screen printing synchronization printing method and mechanism. An existing printing method cannot easily and effectively combine the advantages of digital jet printing with the advantages of traditional rotary screen printing to complete synchronous overprinting in a real sense. The method is characterized by comprising the following steps that (1) printing is conducted on fabric to be printed through a rotary screen to form patterns and register mark points; (2) a front camera is used for photographing the length between every two adjacent register mark points on the printed fabric to obtain the actual rotary screen repeat, and the deviation value of the rotary screen is obtained; (3) corresponding zoom operation is conducted on the digital jet printed patterns according to the deviation value of the rotary screen, and after digital jet printing, digital patterns and digital mark points are formed on the printed fabric; and (4) a rear camera is used for photographing the actual position between the matched register mark points and digital mark points, and whether the accurate overprinting effect is achieved completely or not is judged. The digital jet printing and rotary screen printing synchronization printing method and mechanism really and effectively combine the advantages of digital jet printing and the advantages of traditional rotary screen printing.

Description

technical field [0001] The invention relates to a printing method and a printing mechanism, in particular to a printing method and a printing mechanism in which digital jet printing and rotary screen printing are synchronized. Background technique [0002] At present, digital printing has obvious advantages over traditional rotary screen printing in terms of printing diversity. For example, when an image has more than 10 colors, traditional rotary screen printing needs more than 10 rotary screens to complete color registration, while digital printing only needs Simply import the image into the software and print it directly. However, due to the slight differences in the processing accuracy and working status of the nozzles used in digital printing, these small differences will easily lead to color differences in the pattern printed with a full background color, while the traditional rotary screen printing will print a pattern with a full background color. , the color differ...

Problems solved by technology

Now there is a technology combining digital inkjet printing with rotary screen printing, as disclosed on December 24, 2014, in a Chinese patent with publication number CN204037030U, which discloses a rotary screen and digital inkjet for textile printing Hybrid printing machine, although the printing machine integrates the functions of rotary screen printing and digital inkjet printing, it can meet the printing and dyeing operations of products with complex patterns and diverse patterns, and the printing and dyeing cycle is short, but the printing machine is only simple. Combination of screen printing and digital inkjet printing

To sum up, it is still difficult to really effectively combine the respective advantages of digital printing and traditional rotary screen printing. Using traditional rotary screen printing background color, digital printing prints complex and fine parts of the pattern, and completes the printing process through synchronous overprinting of the two.
