imagemagick - 如何使用 imagemagick 将 adobe icc 配置文件应用于图像

Question

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 -profile CoatedFOGRA27.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，无法使用合并的 ICC 配置文件，因为配置文件 ICC 不正确。配置文件将被忽略。

当我使用 identity 命令检查图像的 -verbose 时，我将色彩空间设为 sRGB。我可以看到颜色配置文件已添加到图像中。但我不明白 adobe ps 有什么不同。添加 -colorspace CMYK 会将颜色空间从 -sRGB 更改为 CMYK，但效果并不好。输出中的颜色甚至不接近真实输入。

C:\test\profile>magick identify -verbose cmyk_playbook.jpg

我是 icc 个人资料的新手，任何帮助将不胜感激。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 颜色配置文件的 imagemagick 使用指南

编辑 2 根据 Fred 的评论，当我将 imagemagick 字符串修改为（来自 imagemagick 配置文件部分）时，我得到了更好的结果

magick convert Playbook.jpg -profile AdobeRGB1998.icc -profile CoatedFOGRA39.icc cmyk_playbook.jpg
