Embodiment 1

[0069] This embodiment provides an image printing method, including:

[0070] S1. Acquire a first color image corresponding to the CMYK color mode.

[0071] Wherein, the first color image is a picture-text image in a point-and-click book, and the initial color mode of the picture-text image is CMYK, that is, the color of each pixel is formed by mixing cyan, magenta, yellow and black.

[0072] S2. Convert the first color image into a second color image corresponding to the CMY color mode.

[0073] Optionally, converting the first color value of each pixel in the first color image to a second color value corresponding to the LAB color mode to obtain a fourth color image;

[0074] converting the second color value of each pixel in the fourth color image to a third color value corresponding to the CMY color mode to obtain a second color image.

[0075] Optionally, obtain a preset color profile;

[0076] Converting one or more first color images into one or more second color ima...

Embodiment 2

[0089] This embodiment provides an image printing terminal, including one or more processors 1 and a memory 2, the memory 2 is stored with a program, and is configured to perform the following steps by the one or more processors 1:

[0090] S1. Acquire a first color image corresponding to the CMYK color mode.

[0091] S2. Convert the first color image into a second color image corresponding to the CMY color mode.

[0092] Optionally, converting the first color value of each pixel in the first color image to a second color value corresponding to the LAB color mode to obtain a fourth color image;

[0093] converting the second color value of each pixel in the fourth color image to a third color value corresponding to the CMY color mode to obtain a second color image.

[0094] Optionally, obtain a preset color profile;

[0095] Converting one or more first color images into one or more second color images corresponding to the CMY color mode according to the color profile.

Abstract

The invention relates to the field of printing and particularly relates to an image printing method and terminal. The method comprises the steps of S1, obtaining a first color image corresponding to aCMYK color mode; S2, converting the first color image into a second color image corresponding to a CMY color mode; S3, obtaining a point reading code image corresponding to the second color image, wherein a color of a point reading code in the image is black; S4, synthesizing the second color image and the point reading code image to obtain a third color image corresponding to the CMYK color mode; and S5, printing the third color image. The image carrying the point reading code can be printed through utilization of a CMYK four-color printing device which is generally used by a factory.

Description

technical field [0001] The invention relates to the field of printing, in particular to an image printing method and a terminal. Background technique [0002] The CMYK color mode refers to the four-color printing mode, which is a color registration mode used in color printing. Using the principle of color mixing of three primary colors of color materials, plus black ink, a total of four colors are mixed and superimposed to form the so-called "full-color printing". Among them, C represents cyan, M represents magenta, Y represents yellow, and K represents black. At present, factories generally use CMYK four-color printing equipment. The dot-reading codes in the dot-reading books are usually expressed in black, and the black ink used in digital printing inks contains carbon elements, and it is impossible to distinguish the black version of the printed graphics and text from the black version of the dot-reading codes, so the CMYK color mode is used for printing Clicking on the...
