Embodiment Construction

[0030] In the present invention, the background layer and the digital layer of the color vision classification detection map are designed and produced, and the background layer and the fixed color of the detection map are output at different given positions of the same printing material with inks (or inks, toners, dyes) of different spectral primary colors respectively. The digital layer and the variable digital layer make the colors of the background layer and the variable digital layer form a near-metameric color sample pair. The color spectral reflectance curves of the background layer and the variable digital layer are quite different, and the CIEDE2000 color difference values ​​calculated by different color matching functions are quite different. Observers with normal color vision have different spectral responses of red, green, and blue cone cells, and some observers recognize the large color difference between the background layer and the digital layer, and can clearly r...

Abstract

The invention relates to a method for making a color vision classification detection map. A detection map is made in the image processing software. The detection map includes two parts: the background layer and the digital layer. The digital layer includes a fixed digital layer and a variable digital layer. There is a certain color difference between the fixed digital layer and the background layer. The eye can clearly recognize the difference between the two colors; the color of the variable digital layer and the background layer are close to or the same, but the spectral reflectance curve has a large difference, forming a near-metameric pair or a metameric pair; choose two different Spectral primary color inks, inks, toners or dyes, reproduce the background layer of the inspection map-fixed digital layer and variable digital layer, and form a color vision classification inspection map on the printing material. The detection map can quickly and conveniently classify the spectral response capabilities of red, green and blue cone cells of normal color vision observers, thereby dividing the color discrimination ability of normal color vision observers.

Description

technical field [0001] The invention relates to a method for making a color vision classification detection map. By selecting inks (or inks, toners, and dyes) of different spectral primary colors, the background layers and digital layers of the detection map are output at different positions of the same printing material. It is required to substitute different color matching functions I and II to calculate the CIEDE2000 color difference between the background layer and the digital layer. Observers with normal color vision, when viewing the test map, some observers can clearly read the numbers on the background layer, that is, they are classified as observer I; some observers cannot clearly read the numbers on the background layer, that is, they are classified as Observer II. The detection map is similar to the color blindness detection map, which can quickly and conveniently classify the spectral response capabilities of red, green and blue cone cells of normal color vision o...
