ICC profile conversions and Adobe CMM

[davidmoy]

Hi all,

I have technical question about the capabilities of ImageMagick and ICC profile conversions.

I am very new to image Magick but wondered if it could replicate Adobe colour management module in terms of ICC profile conversions. I have tested some ICC conversions using ImageMagick for instance Adobe RGB 1998 to CMYK isocoatedv2eci but the conversions look different in terms of colour and contrast than Photoshops conversions. Does anyone know if there is a way to simulate Photoshops ICC profile conversions so I can get an identical match or is this something that is not possible...?

Thanks in advance

David

what IM command did you use. did you specify both profiles. the first should match the profile used in the file and the second should be the new profile that you want. see http://www.imagemagick.org/Usage/formats/#profiles

Hi fmw42

I did specify the ICC colour profiles. See below

Example 1
source ICC profile - Adobe RGB1998
destination ICC profile - isocoatedv2eci

Example 2
source ICC profile - isocoatedv2eci
destination ICC profile- Adobe RGB1998

Three examples of colour utility platforms on PC and Mac
Apple Colorsync
Adobe
Windows color system

What conversion engine is possible using ImageMagick software...?

thankyou

Sorry, i do not know anything further. I just wanted to make sure your command line syntax is correct. Can you show me your actual command line? I have usually used for going to CMYK, USWebCoatedSWOP.icc You might give that a try. Can you post a link to one image that is not coming out correctly (both the input, output from IM and output from PS)?

Also what version of IM are you using?
