Printing mechanism achieving synchronous digital printing and rotary screen printing and printing method

Abstract

The invention relates to a printing mechanism achieving synchronous digital printing and rotary screen printing and a printing method. A printing method for effectively combining digital printing and rotary screen printing to finish synchronous overprinting is hardly achieved at present. The printing method comprises the following steps that firstly, a rotary screen conducts printing on a printed fabric, and a screen printing pattern is formed; secondly, feature points are assigned on the screen printing pattern, feature points in a front rotary screen circumference and a rear rotary screen circumference are shot through a front camera, and the deviation value of the rotary screen is obtained; thirdly, the digital printing pattern is subjected to corresponding zooming operation according to the deviation value of the rotary screen, and after digital printing, a combined printing pattern is formed on the printed fabric; and fourthly, corresponding feature points of the combined printing pattern or corresponding feature points of the screen printing pattern and the digital printing pattern are shot through a rear camera, whether deviation exists between digital printing and rotary screen printing or not is detected, and whether an accurate overprinting effect is completely achieved or not is judged. According to the printing mechanism and the printing method, respective advantages of digital printing and rotary screen printing are truly and effectively combined.

Description

technical field [0001] The invention relates to a printing mechanism and a printing method, in particular to a printing mechanism and a printing method in which digital 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 simple 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 difference...

Problems solved by technology

Now there is a technology that combines digital printing with rotary screen printing. For example, in the Chinese patent whose publication date is December 24, 2014, and whose publication number is CN204037030U, a hybrid of rotary screen and digital inkjet printing for textile printing is disclosed. 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. The combination of printing and digital inkjet printing has not proposed a synchronous scheme for rotary screen printing and digital inkjet printing, and it is impossible to achieve a perfect combination of rotary screen printing and digital inkjet printing, let alone accurate overprinting of the two

In summary, it is still difficult to effectively combine the respective advantages of digital printing and traditional rotary screen printing
