Description
Technical Field
The present invention relates to the field of inkjet printing, and in particular, to a printing control method, apparatus, printing system, and storage medium.
Background
With the rapid development of the inkjet printing technology, the printing equipment and the code spraying equipment are more and more widely applied, and the requirements on the printing speed, the printing precision and the printing effect are higher and higher. The printing system comprises a printing nozzle for jetting ink to a printing medium and a carrying piece for carrying the printing medium, wherein the printing nozzle is generally arranged above a conveyor belt. When the printing system is used for printing, the position of a nozzle in the printing system is kept unchanged, the printing medium moves, and when the printing medium moves below the printing nozzle, the printing nozzle can jet ink to the printing medium so as to print an image to be printed on the printing medium.
The inkjet printing system is generally applied to an assembly line, and prints some personalized patterns on the surface of some objects: such as common application scenarios: printing a label or a bar code on a mobile phone battery, printing a bar code or a two-dimensional code on a packaging bag, printing a two-dimensional code on a bottle cap and the like.
Because the printing nozzle of the ink-jet printing system is generally away from the printing medium by a certain distance, generally more than 2mm, and the printing height of some printing nozzles can reach 2cm, the ink drop sprayed by the printing nozzle has a flight time to the printing medium, and the drop position of the initial printing position is related to the nozzle height and the movement speed of the printing medium. Generally, in the case of the same head type, the printing height is also fixed, and therefore the moving speed of the material directly affects the ejection position of the image. The precision of the starting position of the image at different speeds directly influences the quality of the product, and the defective product or the waste product is formed if the position is deviated. If different media or printing speeds are different, and a large production line needs a long time to accelerate to a specified printing speed, parameters need to be readjusted, and the adjustment is repeated for many times, so that the production efficiency of the production line is directly influenced.
