An inkjet printing system and an automatic deviation correction method for the inkjet printing system

Abstract

The invention discloses an ink-jet printing system and an automatic deviation correction method for the ink-jet printing system. The system comprises a printing unit, a recognition detection unit andan automatic deviation correction system, wherein the printing unit comprises a printing module and a printing module cross beam; the printing module cross beam stretches over a conveying platform; the printing module is mounted on the printing module cross beam; a spray head is mounted below the printing module; the recognition detection unit comprises a photographing device and a photographing device supporting beam; the photographing device supporting beam is arranged on one side of the paper feed end of the printing module cross beam and stretches over the conveying platform; the photographing device is mounted on the photographing device supporting beam; the automatic deviation correction system instructs the printing unit to conduct printing according to information fed back by the recognition detection unit, not conduct printing on paper sheets with large offset and conduct automatic real-time deviation correction treatment on the paper sheets within an offset value preset rangeso as to print images in accurate locations. The ink-jet printing system is applied to a continuous conveying assembly line, achieves automatic real-time deviation correction function, guarantees theprinting quality and improves the printing efficiency.

Description

technical field [0001] The invention relates to an inkjet printing system and an automatic deviation correction method for the inkjet printing system, in particular to an inkjet printing system that automatically corrects printing deviations of inkjet images in real time during the continuous printing of single-page paper by a Onepass (one-pass inkjet) printing system. A deflection correction method for an ink printing system and an inkjet printing system. Background technique [0002] At present, during the working process of the inkjet printing system in the industry, the nozzles of the printing system eject ink droplets to form inkjet graphics on the printing medium. During the inkjet process, the printing module is still, and the printing paper under the nozzle passes through one direction at a high speed in sequence. The printing accuracy and printing width of the nozzles are very high when using one-time paper-feeding imaging inkjet printing. The printing accuracy of ...

Problems solved by technology

In some specific applications, such as printing continuous transmission of single-page paper, some logos have been pre-printed on the paper and the peripheral frame of the image needs to be sprayed, and the printer needs to quickly spray the QR code in the pre-printed frame. After the printing paper moves slightly, the two-dimensional code will shift from the center position of the initially set frame to one side of the frame, or even move out of the frame, which will lead to a decline in printing quality and unqualified products
