Problems solved by technology

Due to batch and process reasons, the hardware characteristic parameters of inkjet ink cartridges have a certain degree of discreteness, especially the setting of the inkjet interval time will cause the subsequent inkjet ink to scatter and scatter, and cannot be concentrated to the desired printing position, which reduces the printing effect
Different ink cartridges have different ink ejection intervals. However, the existing technology is to determin

Abstract

The embodiment of the invention discloses a method for determining the ink-jet interval time. A plurality of scanning images are obtained by scanning a plurality of test samples obtained by printing at different ink-jet time intervals; each scanning image is subjected to gray processing to obtain a corresponding ink mark gray image; a test area corresponding to each printing test point is determined, and each test area includes a plurality of pixels; a scatter distribution matrix corresponding to each ink mark gray image is determined according to gray values of the multiple pixels in each test area; a preset convergence threshold is obtained; a convergence interval corresponding to the corresponding ink mark gray image is determined according to the corresponding scatter distribution matrix and the preset convergence threshold; and the ink-jet interval time corresponding to the ink mark gray image with the minimum convergence interval is determined as the target ink-jet interval time,thus the ink-jet printing quality is improved, and the ink-jet interval time is automatically determined.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device, computer equipment and storage medium for determining an inkjet interval. Background technique [0002] Inkjet technology is a new non-contact, pressureless, and plateless printing technology. It can be printed by inputting the information stored in the computer into the inkjet printing machine. For example, the inkjet printing sub-module in the financial instrument bill module It is used to print information such as bill receipts. Due to batch and process reasons, the hardware characteristic parameters of inkjet ink cartridges have a certain degree of discreteness, especially the setting of the inkjet interval time will cause the subsequent inkjet ink to scatter and scatter, and cannot be concentrated to the desired printing position, which reduces the printing effect . Different ink cartridges have different ink ejection intervals. However, ...
