Hi,
How can I ensure to have an (embedable) Abstract profile as result?
Abstract profiles are not embedeable, but you could try instead:
icclink -t1 -x -o softproof.icc *sRGB cmyk.icc cmyk.icc *Lab
That would generate an input profile softproofing rel.colorimetric intent of
cmyk.icc
Regards
Marti.

Hello again,
What about using abstract profiles?
I have problems understanding the Syntax of icclink.
There is an Example in the manpage:
icclink -t1 -x -o softproof.icc *Lab cmyk.icc cmyk.icc *Lab
I creates an abstract profile.
I tried to adapt it to use with sRGB-image-data, finding out, that I
actually don´t understand it.
Can you tell me how the order in the mentioned Example leed to a proof?
While experimenting the resulting profile switched between Abstract and
DeviceLink-Profile.
How can I ensure to have an (embedable) Abstract profile as result?
Thanks
Thorsten

Hi,
In theorie i would:
- transform source to simmulation with perceptual intend -> step 1
- transform step 1 to output with absolute rendering intent (I want to
simmulate th paper whitepoint)
This would almost work. Is just a little bit more
complex, as the softproof requires mixing intents.
The complete workflow would be something like:
Input(RGB)-> [Perceptual] -> Proof(CMYK)
Proof(CMYK) -> [Rel.colorimetric] ->Proof(Lab)
Proof(Lab) -> [Abs.colorimetric] -> Output(RGB)
lcms implements that by the softproofing transform, which takes
care of all the details (BP compensation, gamut check and so)
Current version of icclink does NOT uses this kind of color
transforms, so you have to write a small program in order to embed
this transform into an ICC devicelink.
Having said that, maybe a devicelink is not your best option, as
you plan to use it as input profile (W3C doesn't allow devicelinks
AFAIK)
Hope this helps

Subject: [Lcms-user] icclink - device Link profiles usage
Hello,
I´m not sure, if i do understand the device-link-profiles (DLP) in the
right sense. My idea is to use a DLP for a proof scenario:
- I have a picture coded in sRGB (source-color-space)
- I want so simmulate a CMYK-print-process e.g. Euroscale-Coated
(simmulated-color-space)
-I want to display it on my output-device: a sRGB-Monitor
(output-color-space)
In theorie i would:
- transform source to simmulation with perceptual intend -> step 1
- transform step 1 to output with absolute rendering intent (I want to
simmulate th paper whitepoint)
My Questions are:
- can I create such a chain with icclink by commandline?
- Can someone give me some hints for icclink
- how do I use the DLP? I want to use it within profile-tag of W3C´s
CSS3-Spec, but threr is no browser at this time, to support these Tags.
- or did I get on the wrong track and misinterpreted the use of DLP
Thanks
