Embodiment 1

[0051] Taking 500nm light yellow-green as an example, the preparation method and process of the anti-myopia yellow-green color of the present invention will be described in detail.

[0052] Step 1, through the CIEXYZ chromaticity coordinates, search for the spectral tristimulus value of the anti-myopia color block corresponding to 500nm X=0.0049, Y=0.3230, Z=0.2720 and chromaticity coordinates x=0.0082, y=0.5384, z=0.4534, use CIE1976Lab horseshoe-shaped curve, find the yellow-green color block to prevent myopia in the horseshoe-shaped curve;

Abstract

A method for mixing myopia-preventing spot-color ink comprises the steps of (1) establishing a myopia-preventing yellow-green color block; (2) determining the size of the yellow-green color block as 4cm*4cm-6cm*6cm and measuring the density of the yellow-green color block to obtain a color block density value; (3) determining an ink proportion by adopting an ink mixing method according to the color block density value obtained in the step (2); (4) carrying out ink mixing according to the ink proportion obtained in the step (3) to obtain the expected myopia-preventing yellow-green color block; (5) carrying out color difference evaluation on the myopia-preventing yellow-green color block obtained in the step (4) based on a color difference formula. According to the method for mixing myopia-preventing spot-color ink, the yellow-green color block through which eyes are not prone to fatigue is built to serve as a myopia-preventing target color, the myopia-preventing ink color is mixed by means of a masking equation, and the ink mixing method is used for replacing a paper-making process which is high in cost and results in serious pollution. Therefore, the method for mixing myopia-preventing spot-color ink is simple, is convenient to implement, and largely lowers the cost of myopia-preventing products.

Description

technical field [0001] The invention belongs to the technical field of spot-color ink preparation, and relates to a method for preparing spot-color ink for preventing myopia. Background technique [0002] Spot color ink blending refers to the adjustment of the printability or color of the ink by adding a certain amount of additives to two or more inks. Yellow-green is the best color for the eyes. The 555nm reflection spectrum is the most sensitive spectrum for vision. When observing this color, the eye fatigue is the least, and the eyes can see the most clearly, which can reduce the effect of visual fatigue. At present, the main method for preventing myopia is to bleach the pulp to a certain color through the papermaking process to achieve the purpose of preventing myopia. The papermaking process is complex, costly, and easily pollutes the environment. [0003] At present, there are mainly the following methods for spot color ink blending: (1) database search method, the ...
