Image processing based printer ink amount setting method and device, image processing based printer ink amount setting equipment and medium

Abstract

The invention discloses an image processing based printer ink amount setting method and device, image processing based printer ink amount setting equipment and a medium. The printer ink amount settingmethod comprises the following steps of acquiring a color value of the printing medium, and recording the color value as a first color value; performing graying processing on a to-be-printed image according to the first color value to obtain a first grayscale image; traversing the first grayscale image to obtain a first grayscale value of each pixel point in the grayscale image; comparing the first grayscale value with a set color threshold to obtain a comparison result; and setting an ink amount value of a printer white ink channel when the to-be-printed image is printed according to the comparison result. According to the image processing based printer ink amount setting method and device, the image processing based printer ink amount setting equipment and the medium, the ink amount canbe saved, the printing cost is reduced, and meanwhile the printed image is good in transition and touch hand feeling.

Description

Technical field [0001] The invention relates to the field of inkjet printing, and in particular to a method, device, equipment and medium for setting ink volume of a printer based on image processing. Background technique [0002] Inkjet printers spray colored liquid ink into fine particles through nozzles onto the printing medium. With the continuous advancement of technology, the colors and materials of printing media are becoming more and more abundant, so it often appears that the color of a large area in the image to be printed is the same as the color of the printing medium. At this time, if all the pixels in the image are still displayed Ink, this will cause ink waste. Especially in the textile industry, when printing color images, it is necessary to print a layer of white ink with an ink volume value of 100% for the bottom layer. This will not only waste color ink, but also waste white ink, which increases the cost of printing. Existing ink-saving methods are all consid...
