A printing mechanism and printing method for synchronous digital printing and rotary screen printing

Abstract

The invention relates to a printing mechanism and a printing method for synchronizing digital printing and rotary screen printing. It is still difficult to effectively combine digital and rotary screen printing to complete the printing method of synchronous overprinting. The steps of the printing method of the present invention are as follows: (1) use a rotary screen to print on the printed fabric to form a screen printing pattern; (2) designate feature points on the screen printing pattern, and use the front camera to take pictures of the features in the front and back of the two flowers. Points to get the deviation value of the rotary screen; (3) According to the deviation value of the rotary screen, the digital printing pattern is scaled accordingly, and after digital printing, a combined printing pattern is formed on the printed fabric; (4) After using the The camera shoots the combined printing pattern or the corresponding feature points of the screen printing pattern and the digital printing pattern, detects whether there is a deviation between the digital printing and the rotary screen printing, and judges whether the effect of accurate overprinting has been fully achieved. The invention effectively combines the respective advantages of digital printing and traditional rotary screen printing.

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] The current 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 requires 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 small differences in the processing accuracy and working conditions of the nozzles used in digital printing, these small differences can easily lead to color differences on the printed patterns with full background color, while traditional rotary screen printing is printed with full background color patterns. When the color difference cont...

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
