The invention provides a method and a device for eliminating white marks in spray head assembly positions. The method comprises the following steps: obtaining the width nwidth of a repeat region of two adjacent spray head assembly positions; determining a period n of forming a sine curve by lattice points in the repeat region according to the width nwidth of the repeat region; calculating division points in the repeat region according to the width nwidth of the repeat region and the period n of forming the sine curve by the lattice points in the repeat region, so that the two adjacent spray heads are respectively in charge of two partial repetition regions obtained by diversion through the diversion points; after the two adjacent spray heads jet ink successfully according to the division points, re-calculating the division points in the repeat region according to the width nwidth of the repeat region and the period n of forming the sine curve by the lattice points in the repeat region, so that a connecting line formed by the division points is in a sine curve trend.
Description
technical field [0001] The invention relates to the technical field of digital inkjet printing, in particular to a method and a device for eliminating white spots at splicing positions of nozzles. Background technique [0002] In the prior art, for the digital printing equipment commonly used for inkjet printing of ceramics, the nozzle is under the control of the control system. When the ceramics are transported to the predetermined position through a long conveyor belt, the piezoelectric crystals in each nozzle of the nozzle generate pulses to transfer the ink. Extrude and spray mist ink droplets directly onto the surface of the ceramic for imaging. [0003] Due to the relatively large format of the ceramics and the relatively small width of the nozzles, in the prior art, a plurality of nozzles are usually arranged in a row with dislocations up and down, wherein there are multiple overlapping nozzles between two adjacent nozzles. The overlapping area is responsible for ove...
