Description

Ink jet printing method, device, equipment and storage medium for adjusting printing precision Technical Field The present invention relates to the field of inkjet printing technologies, and in particular, to an inkjet printing method, device, apparatus, and storage medium for adjusting printing accuracy. Background In the inkjet printing industry, the nozzle mounting mode is generally shown in fig. 1, the nozzle is parallel to a printing plane determined by an X direction (i.e., a printing direction or a transverse direction) and a Y direction (i.e., a secondary printing direction or a longitudinal direction), and is perpendicular to the X direction, as the requirements of people on printing effects are higher and higher, the variety of requirements on printing precision are also higher and higher, when the requirements on printing precision are not higher and the increase of printing cost is not desired, the nozzle can be obliquely printed in the nozzle oblique mounting mode shown in fig. 2, and compared with the printing mode in which the nozzle is perpendicular to the printing direction, the secondary printing direction printing precision can be improved. However, since the head mounting manner is changed, if the print data is aligned with the head mounting direction when the head is mounted obliquely, the image data is tilted, and the resulting print image is tilted, the print data often needs to be rotated or tilted before printing. In order to improve the printing efficiency, as shown in fig. 3, when the cylindrical object is printed, the spray head always moves to spray ink along the X direction relative to the cylindrical object, and meanwhile, the cylindrical object rotates along the W direction around the axis, which is equivalent to that the spray head tilts a certain angle relative to the surface of the cylindrical object for performing the ink-jet printing, so that the printing data of the cylindrical object is also required to be selected or tilted during the cylindrical object printing. As shown in fig. 4a, each print data (ink dot) should be uniformly tilted after the print data is tilted in an ideal case, but the actual processing situation is often as shown in fig. 4b or 4c, so that the print effect is easily reduced after the print data is tilted or rotated, and the saw-tooth appears easily in the image portion which should be straight, in the prior art, the saw-tooth resisting effect is realized by adjusting the print data, but the processing way brings about a large cost for data processing, thereby affecting the printing efficiency, and the adjustment of the print data may also bring about a change of the image printing result, thereby affecting the final image quality. Disclosure of Invention In view of this, embodiments of the present invention provide an inkjet printing method, apparatus, device, and storage medium for adjusting printing precision, so as to solve the problem in the prior art that print quality is reduced due to data tilting processing during tilting printing or printing of a cylindrical object.
