Embodiment Construction

[0017] In order to make the purpose, technical solution and main points of the present invention clearer, the present invention will be further described below with reference to the accompanying drawings and in combination with specific implementation examples.

[0018] The basic principle of the method for controlling asynchronous multi-nozzle cooperative printing proposed by the present invention is as follows: firstly, the printing data of each nozzle is transmitted into the printing main board controller through multiple channels or data packaging and marking, and after the printing main board controller receives the data , the internal memory manager manages the data of each print head separately, and reasonably adjudicates the data read and write requests of each print head. At the same time, the host print engine program converts the relative position relationship of each nozzle into trigger delay information, which is sent to the trigger management module in the print m...

Abstract

The invention discloses a method for controlling asynchronous multi-nozzle collaborative printing. The method for controlling asynchronous multi-nozzle collaborative printing comprises steps that a host machine printing engine program generates printing data and control information and the printing data and the control information are transmitted to a printing main board controller; the printing data enters into a command parsing and data distributing module through a data channel of the printing main board controller; the command parsing and data distributing module distributes the printing data of nozzles to first level buffer FIFOs respectively; then the printing data is stored into an independent data area of an SDRAM after read-write arbitration through an internal storage controller; the printing data which is required to read through the internal storage controller is temporally stored in second level buffering FIFOs of the nozzles; finally the printing data is sent to the nozzle through driving modules of the nozzles.

Description

technical field [0001] The invention relates to the field of high-speed multi-nozzle printing, in particular to a method for controlling asynchronous multi-nozzle cooperative printing in a wide-format printing system. Background technique [0002] In the past, the text, graphics or barcodes on various packages were often printed by screen printing machines, transfer printing machines or even more primitive mechanical roller punches. The production efficiency of this type of printing method is low, the printing quality is not high, and the clarity of the printed matter cannot meet the requirements. In recent years, many large companies have developed various types of thermal foaming or piezoelectric ceramic high-resolution nozzles. The non-contact continuous inkjet printers developed based on these types of nozzles are characterized by their flexibility, high efficiency, and high printing quality. And the advantages of strong applicability quickly win a broader product marke...
