Problems solved by technology

However, on existing digital printing lines, the distance between adjacent nozzles is mostly judged by human eyes, which not only requires a lot of manual adjustment and takes a lot of time, but also depends on the experience of workers, which is not conducive to standardized production

Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below.

[0034] Such as figure 1 As shown, a multi-nozzle adjustment method for overprinting includes the following steps:

[0035] (1) Coarse adjustment stage

[0036] Print the calibration and test chart, calculate the actual distance between adjacent nozzles through the calibration and test chart, and input it into the inkjet printing system for preliminary parameter correction. Step (1) includes the following steps:

[0037] (11), jet printing calibration and test chart (such as figure 2 shown);

[0038] (12), the image of the calibration and the test chart of the collection step (11) jet printing;

[0039] (13), analyze the collected image of step (12):

[0040] (131) Determine the correspondence relationship Fy between the physical distance / pixel

[0041] The physical distance between the two adjacent calibration lines of the calibration and test chart is constant, set as Yd, and meas...

Abstract

The invention belongs to the field of digital printing, and particularly relates to a multi-nozzle adjusting method for overprinting. The method comprises the following steps: (1), in coarse adjustment stage: printing a calibration chart and a test chart, calculating the actual distance of adjacent spray heads according to the calibration chart and the test chart, and inputting the actual distanceinto a spray printing system for preliminary parameter correction; and 2, in fine adjustment stage: printing a fine adjusting chart, and inputting the calculated deviation into the spray printing system for further parameter correction. The method has the following beneficial effects: 1, high automation degree, specifically, front and back splicing effects and parameters of the spray heads are directly adjusted by equipment without manual adjustment, so that manual work is reduced; and 2, quick adjustment, specifically, adjustment and preparation time are reduced.

Description

technical field [0001] The invention belongs to the field of digital printing, and in particular relates to a multi-nozzle adjusting method for overprinting. Background technique [0002] Overprinting refers to the overlapping registration of graphic and text printing of each color plate during multi-color printing, that is, the monochrome printing plates with different screen line angles obtained after color separation of the original, are overlapped and aligned in sequence according to the color sequence of the printing plate, and the final printing result is the same as that of the printing plate. Prints with the same level and tone as the original. However, on existing digital printing lines, the distance between adjacent nozzles is mostly judged by human eyes, which not only requires a lot of manual adjustment and consumes a lot of time, but also relies heavily on the experience of workers, which is not conducive to standardized production.
