How to convert file with CMYK color space?
Question: I am converting a TIFF file with CMYK color space without
any embedded profile into a file with RGB colorspace (JPEG, GIF, BMP,
TIFF, PNG). The resulting image differs from the image I obtain using
Adobe Photoshop. How do I get the result similar to that of Photoshop?
Answer: You should specify the profile used when processing an
image with CMYK color space into RGB. To get the result similar to that
of Photoshop specify the profile used by Photoshop.
Example:
ICPCL.exe -convertto tiff bpp:24 dither:no -source "C:\Source Images\cmyk.tif" -dest "C:\out" -oper ColorProfile profile_path:"C:\WINDOWS\system32\spool\drivers\color\Photoshop4DefaultCMYK.icc"
