Embodiment Construction
[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0019] see figure 1 The structural diagram of the jet printing device shown, the device includes: multiple rows of misplaced nozzles; the controller, including:
[0020] The data splitting module is used to divide the data of the image into multiple parts, and the number of parts is equal to the ratio of the resolution of the image to the resolution of each nozzle;
[0021] The selection module is used to select the rows of nozzles of the number of nozzles at equal intervals among the multi-row nozzles arranged in a staggered position;
[0022] The printing module is used to control each selected nozzle row to print one copy of the data.
[0023] The staggered arrangement of the nozzles in this application means that under the control of the controller, the intervals between the pixels printed by the nozzles of each row are equal o...

The invention provides a digital jet printing device and a control method. The device comprises a plurality of rows of nozzles which are arranged in a stagger mode and a controller. The controller comprises a data splitting module, a selection module and a jet printing module, wherein the data splitting module is used for splitting data of an image into a plurality of pieces, and the number of the pieces is equal to the ratio of the resolution of the image to the resolution of each nozzle; the selection module is used for selecting nozzle rows of the pieces at equal intervals in the plurality of rows of nozzles which are arranged in the stagger mode; and the jet printing module is used for controlling each selected nozzle row to print one piece of data. By means of the digital jet printing device and the control method, through jet printing of the plurality of nozzles under the control of the controller, the resolution of a jet-printed image exceeds the resolution of a jet-printed image by a single nozzle, and the jet printing quality is improved.
Description
technical field [0001] The invention relates to the field of printing, in particular to a digital jet printing device and a control method. Background technique [0002] Digital printing technology directly processes, transmits and prints image data. Since the digital printing technology uses the on-demand inkjet printing nozzle as the core imaging component, the nozzle of the nozzle and the surface of the substrate usually maintain a distance of about 1 mm, so the digital printing technology is called non-contact printing. [0003] There are a series of small channels inside the nozzle. During the printing process, the mechanical effect generated by the piezoelectric crystal squeezes the ink out of the channel and directly sprays it to the predetermined position on the surface of the substrate. [0004] Limited by the mechanical manufacturing process of the nozzle, the highest resolution of the nozzle is certain, and the existing digital printing technology cannot print an...
