我正在尝试使用从adobe网站下载的配置文件将rgb图像转换为cmyk。
我正在使用的命令如下：
转换Playbook.jpg-涂有涂层的FOGRA27.icc cmyk_playbook.jpg
当我尝试在photoshop上打开输出图像时，我收到一个错误，指出无法使用并入的ICC配置文件，因为配置文件ICC不正确。该个人资料将被忽略。
当我使用identity命令检查图像的-verbose时，我得到的色彩空间为sRGB。我可以看到颜色配置文件已添加到图像中。 但是我不明白adobe ps是如何做的不同。添加-colorspace CMYK会将颜色空间从-sRGB更改为CMYK，但是效果不佳。输出中的颜色甚至不接近实际输入。

我是icc个人资料的新手，我们将不胜感激。如果您需要有关此处完成的测试的任何信息，请告诉我。我指的是我的测试imagemagick color profile
的imagemagick使用指南编辑2 根据弗雷德（Fred）的评论，当我将imagemagick字符串修改为（从imagemagick配置文件的部分引用）时，我得到了更好的结果
magick convert Playbook.jpg -profile AdobeRGB1998.icc -profile CoatedFOGRA39.icc cmyk_playbook.jpg
