Embodiment Construction

[0020] figure 1 It is a flow chart of a repair method for dot gray scale distribution of inkjet printer plugging provided by an embodiment of the present invention. Such as figure 1 As shown, the method for repairing the inkjet printing machine plug dot grayscale distribution provided by this embodiment includes:

[0021] Step 100, obtain the gray value A of the first dot of the current gag, the gray value B of the second dot located directly to the left of the first dot, and the gray value of the third dot located directly to the right of the first dot value C, and get the total gray value S after summing.

[0022] specifically, Figure 8 A schematic diagram of the dot distribution in the method for repairing the gray scale distribution of the dot dots of the inkjet printer plug is provided for the embodiment of the present invention. Such as Figure 8 As shown, find the column in the image to be printed corresponding to the inkjet printer’s clogging, and scan from top t...

Abstract

The invention provides a repairing method and device through gray scale distribution of blocked nozzle dots of an ink-jet printer. The method comprises the following steps: the gray scale value A of a first dot of the current blocked nozzle, the gray scale value B of a second dot on the left of the first dot and the gray scale value C of a third dot on the right of the first dot are acquired, and a total gray scale value S is obtained after summation; and the total gray scale value S is distributed to dots on the left side and the right side of the first dot. According to the method, the gray scale value A of the current first dot, the gray scale value B of the second dot on the left of the first dot and the gray scale value C of the third on the right of the first dot are acquired, and the total gray scale value S after summation is distributed to the dots on the left side and the right side of the first dot, so that gray scale loss caused by blocked nozzles can be reduced effectively, and the printing quality can be improved.

Description

technical field [0001] The invention relates to digital printing technology, in particular to a method and a device for repairing the dot gray scale distribution of inkjet printing machine plugging. Background technique [0002] Digital inkjet printing technology is a printing technology that has developed rapidly in recent years. Digital inkjet printing is a printing method that directly transmits, processes and prints data, that is, the original data is color-separated and hung on the net to generate an image format that can be printed by a digital inkjet printer. The image content is transmitted to the control system, and the control system controls the inkjet head of the digital inkjet printing machine to directly inkjet the image. [0003] For commonly used digital inkjet printers, the inkjet head is under the control of the control system. When the surface of the substrate (such as paper) reaches a predetermined position, the piezoelectric crystal in the nozzle of the ...
