Technical Field

The embodiment of the application relates to the technical field of printing, in particular to a multi-nozzle printing device and a printing method thereof.

Background

The inkjet printing technology refers to a technology for realizing image printing by controlling a head to eject ink droplets onto a printing medium. Ink jet printing is divided into two modes of multiple Pass and OnePass: the multi-Pass generally comprises a printing trolley driving a spray head to do reciprocating motion, and a printing stock doing stepping motion; generally, the OnePass needs to make a spray head fixed, a printing stock moves under the drive of a mechanical device, and the spray head sprays ink onto the printing stock once every certain movement distance to finally form a required pattern.

The minimum unit of the spray head is a spray hole, and due to the maximum spray frequency of one spray hole and the limitation of the volume of single-spray ink, the paper feeding direction resolution of a printing stock is inversely proportional to the paper feeding speed in OnePass printing, namely the faster the paper feeding speed is, the lower the paper feeding direction resolution is. In the prior art, in order to improve the resolution in the paper feeding direction, the amount of printing ink per unit area is generally kept sufficient by reducing the paper feeding speed. The printing mode can only realize the printing of quantitative ink drops on a printing stock, can only meet the single printing requirement, and cannot adapt to various printing scenes. In addition, the distance and angle between the printing nozzle and the paper feeding direction of the printing medium and the distance between the printing nozzles in the prior art are specific conditions, so that convenience of printing is limited.

Therefore, how to control the amount of ink ejected to meet the complex printing requirements becomes a problem to be solved by those skilled in the art.
