Title: Re: Inconsistent Embedding of Color Profile in Photoshop CS
Hi Stephan,
1.- AppleScript stuff
I think that’s better idea to use AppleScript over Photoshop actions, is
much faster. I work a lot with Photoshop and Color Profiles and AppleScript,
not strange, because I’m a photographer and this works for me, all the time:
tell application "Adobe Photoshop CS"
set MiDoc to document 1
my Verifica_Perfil_Espacio()
set MiDoc2 to ((path to desktop as string) & "test") as Unicode text
save MiDoc in MiDoc2 as Photoshop format with options {embed color profile:true}
end tell
on Verifica_Perfil_Espacio()
tell application "Adobe Photoshop CS"
tell current document
if mode is not RGB then change mode to RGB
if color profile name is not "Adobe RGB (1998)" then convert to profile "Adobe RGB (1998)" intent relative colorimetric with blackpoint compensation and dithering
end tell
end tell
end Verifica_Perfil_Espacio
2.- About the Color Profile
You typically, want to save a doc with an embedded color profile because you want that any application that try to open that file “map” the color information correctly, using the space that you use to edit or save the file. When you assign or convert a file to a color profile you are telling Photoshop, or any other application for that matter, to use a specific “Dictionary” to interpret the color information (x,y,Y), if you send this file to other users, or other devices they need to know the ICC Profile in order to display/print correctly. If you don’t save your files with the color profile embedded neither Photoshop, nor other devices will have the info to display/print correctly.
By the way if other users don’t have this Color Profile in their computers, they need a copy of this file also.
If the profile is missing or not present, then Photoshop ask what to do, or just try to use a “Generic” color profile, and then you could get a very bad image.

Hey Stephan,
In your original email you mention you are converting to profile first. Are
you doing this via the "Convert to Profile…" window of the Image --> Mode
menu?
This is the point I believe your chosen profile is physically and
permanently adjusting the colours in your image, hence (if my understanding
is correct) the image no longer needs the profile embedded when saving. Oh,
and is it the same profile being used in both cases or different ones (maybe
justifying both actions used)?

ps. re: Scripting Adobe apps, Photoshop isn't the most complete app to
script but it's not too bad. I was told told by an Adobe rep that the
developers worked really hard with InDesign to make almost everything you
can do in the GUI scriptable.

Brett,
Thanks for your reply. I'm not much of an expert either, I'm just doing as
directed by the "color guys". If you look at a save as dialog box you'll see
there's an option ot embed the profile and theyr'e asking for that to be
done. It looked easy enough because the dictionary for Photoshop CS has a
save option saying embed color profile. What's strange is that it doesn't
reliably work. Sometimes it does, other time it doesn't. It's very, very
frustrating. I then thought recording an action would work, but that
unreliable too.
I'm new to AppleScript programming, but I'm working with some very
experienced AppleScripters and they aren't suprised by my trouble because
it's their experience that Adobe apps are difficult to work with when it
comes to scripting.
Thanks again, Stephan

I can't answer for your inconsistent script issue but, as far as I
understant, your converting to a profile is as locked in as you can get it.
Doesn't it permanently alter the colour values of your image to the profile
you chose, whereas embedding a profile to an image when saving simply gives
a colour output device information on what to do when outputting the image,
but the profile can still be ignored and the image output as it is or
another profile applied?
If this is correct then there is no need to try to embed the profile once
you have already converted to it, in fact, could the embedded profile be
altering the colours again if applied to the image for a second time at the
RIP?
Colour management is an area I don't have a strong enough handle on but am
trying to learn more about so I can be a better help within the design
studio here. Perhaps someone with more colour experience can give you a
definitive answer.
But, I would have thought that the PShop Action would give you consistent
embedding results though.
Cheers,
Coj

I'm pulling my hair out trying to get Photoshop to consistently embed a
color profile. I've tried the following approaches:
1. save current document in file (filename) as Photoshop format with
options {embed color profile:true} 2. I recorded an action that saves the
file and I then call the action
Neither one of these methods works very consistently. Before I'm doing
either of these I apply a profile and then convert to a profile. So the
profile I'm trying to embed is the one that i've just converted the file
to. If I go thru the save process manually it seems to work fine. The way
that I verify that the profile is embeded or not is to use the Color
Management Policies to check for a Profile Mismatch.
Has anyone else run into this problem before?
Thanks, Stephan
