Embodiment Construction

[0019] The multi-point correction method for bidirectional printing of the wide-format inkjet printer of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] When implementing the multi-point correction method of the present invention, at first, as Figure 4 As shown, four calibration points S1, S2, S3, and S4 are selected at intervals along the length direction of the printing platform of the printer, and conventional two-way calibration maps are printed at the four points respectively, to obtain Figure 5 The 4 single-dot bi-directional printing correction charts shown in , the short line is the base color and the long line is the correction color, the base color is printed to the left and the correction color is printed to the right, and the correction values ​​of 4 points are obtained from the figure, among which, the correction value of S1 is -1, the correction value of S2 is -4, the correction value of S3 is -2, ...

Abstract

The invention discloses a multi-point correcting method for bidirectional printing ink drop offset of a broad width ink jet printer, which specifically comprises the following steps: selecting a plurality of correction points on a printing medium at intervals, performing conventional single-point correction for each point respectively to acquire a bidirectional printing correction value of each correction point, establishing a coordinate graph by using a horizontal ordinate to express the length of a printing platform and using a vertical coordinate to express the amplitude of the correction value, connecting every two adjacent correction value points by using a straight line in the coordinate graph to acquire a correction value fold line covering the overall length of the printing medium, and correcting the operations of a printing spray head in the overall length range of the printing medium in a conventional mode according to a series of correction values acquired on the correction value fold line. Through multi-point correction in the overall length range of the printing medium, the influence of the self state of the printing platform to the printing quality is greatly reduced, the manual correcting workload is reduced, the correcting operation after the printer is arranged is simple, feasible and quick, the mounting cost is reduced, and the post maintenance for the printer is convenient.

Description

technical field [0001] The invention relates to a correction method for bidirectional printing of a wide-width inkjet printer, in particular to a multi-point correction method for bidirectional printing ink drop offset of a wide-width inkjet printer. Background technique [0002] During the entire printing process of the inkjet printer, the nozzle moves in the horizontal direction. When the nozzle enters the printing area, the nozzle ejects ink droplets onto the printing medium. Since the nozzle has been moving in the horizontal direction, under the action of inertia, the ink drop still maintains the same horizontal speed as the nozzle after leaving the nozzle hole, that is to say, the ink drop falls in a parabola during the inkjet process, not in a straight line. Fall vertically. This creates an offset between where the ink drop starts to fall and where the ink drop lands on the print media. Such as figure 1 As shown, the print nozzle ejects ink droplets at point B. When...
