求问ColormunkiPhoto给打印机校色的参数设置

异域风景

我参照这篇文章给L801校色，基本已经接近显示器效果了，但还有些问题
http://www.chiphell.com/thread-886382-1-1.html

我按他的参数做 感觉和校样有些许区别

他最后生成icc的设置是

colprof -v -qh -i D50 -o 1931_2 -S "sRGB Color Space Profile.icm" -cmt -dpp -D配置文件名称 1xA4

其中D50 -o 1931_2这个参数是什么？我看他用显示器校色是D65 但打印选择了D50

还有SRGB色域的选择，如过打印的图片是ARGB色域在这个参数上是不是该选ARGB 1998

D50是指目前色温5000K
-o 1931_2意思如下

The -o flag allows specifying a tristimulus observer, and is used to compute tristimulus values. The following choices are available:
  1931_2 selects the standard CIE 1931 2 degree observer. The default.
  1964_10 selects the standard CIE 1964 10 degree observer.
  1955_2 selects the Stiles and Birch 1955 2 degree observer
  1978_2 selects the Judd and Voss 1978 2 degree observer
  shaw selects the Shaw and Fairchild 1997 2 degree observer

Note that if an observer other than 1931 2 degree is chosen, the resulting ICC profile will not be standard, and cannot be freely interchanged with other profiles that that use the standard 1931 2 degree observer. Profiles should only be linked with other profiles that have the same illuminant and observer. The 1978_2 observer or shaw observer may give slightly better results than the 1931_2 observer.

===================================

-S "sRGB Color Space Profile.icm"的解释如下


    -s      -S  In order to generate perceptual and saturation    intent B2A tables for output profiles, it is necessary to specify at    least one profile to define what source gamut should be used in the    source to destination gamut mapping. [For more information on why a source gamut is    needed, see About ICC profiles and      Gamut Mapping] The -S parameter is used to do this,    and doing so causes perceptual and saturation tables to be    generated. If only a perceptual intent is needed, then the -s    flag can be used, and the saturation intent will use the same table    as the perceptual intent. Note that a input, output, display or    device colororspace profile should be specified, not a non-device    colorspace, device link, abstract or named color profile.
    If no source gamut is specified for a cLUT Display profile, then an    ICC Version 2.2.0 profile will be created with only an A2B0 and B2A0    tag. If a source gamut is specified, then an ICC Version 2.4.0    profile will be created with a full complement of B2A tags to    support all intents. The source gamut is created from the    corresponding intent table of the provided profile to the output    table being created. A TIFF or JPEG file containing an embedded ICC    profile may be supplied as the argument.
    Note that input profiles and    matrix profiles will only contain a colorimetric intent table or    matrix, and hence the -s    and -S option is not    relevant.

多谢了，无奈英文苦手，没全看明白

我知道如果完全照片打印应该使用D50色温吧，但如果我的显示器校色是argb D65标准校色的话，是不是这块的生成应该也是按D65和argb色域设置

另外这样做如果打印的照片是srgb色域，需不需要按srgb再生成一个icc，还是argb icc就能完全覆盖srgb照片，不会因为色域变化出现误读

不需要再生成一个sRGB icc,输出什么色域主要看用户需求
