Abstract

The invention discloses an image processing based printer ink quantity regulating method, device and equipment as well as a medium. The printer ink quantity regulating method comprises the following steps: obtaining a color value of the printing medium, and recording the color value as a first color value; obtaining a color value of all pixel points, with background images removed, in a to-be-printed image, and recording the color value as a second color value; obtaining a color difference value corresponding to each pixel point according to the first color value and the second color value; comparing the color difference value with a set color threshold value; and while the color difference value is smaller than the color threshold value, regulating data, in all color channels of a printer, of the pixel points corresponding to the color difference value as data for not discharging ink. The image processing based printer ink quantity regulating method, device and equipment as well as the medium can save ink amount, and reduces printing cost.

Description

technical field [0001] The invention relates to the field of inkjet printing, in particular to a method, device, equipment and medium for adjusting the ink volume of a printer based on image processing. Background technique [0002] Inkjet printing technology refers to the technology of spraying ink droplets onto the printing medium through the nozzles on the nozzle to obtain images or characters. With the continuous advancement of technology, the colors and materials of printing media are becoming more and more abundant, so it often happens that the color of a large area in the image to be printed is consistent with the color of the printing medium. For example, the image to be printed includes background image and foreground image, background image The color of the image is similar to or almost the same as the color of the printing medium, and part of the color in the foreground image is also similar to the color of the printing medium. In view of this phenomenon, the exis...
