Embodiment
Please refer to Fig. 1, the embodiment of the present invention one are as follows: a kind of wide colour gamut color management method, including following content；
Wide colour gamut ink formulations are determined by repeatedly printing test first.Normal printing is tetra- color pattern of CMYK, this implementation
Then example can be cooperated with CYK and be printed by the formula of change M ink, the color for obtaining meeting actual demand is more bright-coloured full
The printed sheet of sum, naturally it is also possible to be realized by changing the formula of other one or more of colors.
A default Electronic Testing document, the Electronic Testing document includes that print control strip, image and colour gamut lead table, to institute
It states Electronic Testing document to be printed on the machine, CTP calibration curve is carried out by G7 method and printed sheet color adjusts, obtains wide colour gamut
The printed sheet of color.In printing machine timing, CYK is made to meet the requirement of ISO12647-2, M meets the recipe requirements after changing, and three
Color ash high light, middle tone and shadow density meet G7 requirement, and grey middle tone contrast HR-cmy=0.54, HR-k=0.50 is bright
Range HC-cmy=0.25, HC-k=0.22 are adjusted, shadow contrast SC-cmy=0.92, SC-k=0.90 pass through such correction side
