A two-cycle step-by-step printing digital inkjet printing machine and printing method

technical field

The invention relates to the new technology field of digital ink-jet printing, in particular to a digital ink-jet printing machine and printing method for two-cycle step-by-step printing.

Background technique

Digital inkjet printing technology is a high-tech product that integrates machinery, computer, electronic information technology and gradually formed with the continuous development of computer technology. It first appeared in the mid-1990s. 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 to textile printing and dyeing. It is known as the textile industry revolution technology in the 21st century, and it will gradually replace traditional printing. The method has become the main equipment for textile printing. In recent years, digital inkjet printing technology at home and abroad has made great progress. Among them, the flatbed digital inkjet printing machine can realize personalized printing of garments, etc., and the technology has been continuously improved, and the types and functions of products have also been continuously improved.

For the fixed-head flatbed digital inkjet printing machine, the client submits the document to the PC host of the printing equipment, and the PC host converts the image information into corresponding printing control commands and The control command is sent to the printing controller to control the printing. During the printing process, firstly, the nozzle group moves a lead in the width direction of the fabric. During the movement, the jet printing controller controls whether the nozzles spray ink according to the obtained jet printing control command; secondly, the servo motor controls the printing plate in the direction of the fabric length. Move one printing width forward, and the two movements coordinate with each other to repeat the above process until the printing task is completed. Compared with the belt-type digital inkjet printing machine, for flat-bed digital inkjet printing equipment, how to increase the printing speed or the number of garments printed each time is the main problem currently facing.
