Assign profile or convert to?

I have seen but not read this discussion a few days ago, do you know where it is, and if not, right now I just need to change profiles from Adobe RGB (1998) to sRGB. Which one?, my files are layered.

Just to be perfectly clear...if you know for an absolute fact that the colors in an image reflect some know color space (like sRGB) then you want to "Assign" a color space...if you don't know for a fact the you might want to investigate further...
Assign presumes that you know the actual color space the image is in...convert (far more likely) takes the colors of the image and actually coverts the image colors to be the corrected image colors...

  • Converting/assigning profiles

    I've been experimenting with various settings in CS (on a mac OS X) and reading this forum (as well as G Ballard's helpful website). Could someone clear up a few questions for me:
    I read on GBallard that I should honor the source file's embedded profile. And that the file's source space should equal PS working space. Also, sRGB is the preferable space for both (am I wrong in that?). My main confusion is in trying to align the file and PS spaces.
    -- in PS working space settings, if I choose US Prepress Defaults as recommended, it automatically chooses Adobe RGB for working space. Should I leave it on this setting, or should I change working space RGB to my monitor RGB (which then changes the setting to 'custom')?
    -- Then -- what should my source space be? my photo files are tagged Camera RGB. Should I convert these files to the same space setting as the PS (such as sRGB)? I use images on both web and an epson R800.
    Basically, I'm really confused about whether I should be changing color profiles at all. I initially started tinkering because my prints were so dark and muddy, and changing profiles seemed to help. (AppleRGB worked best, for some reason) I'm now more or less getting the results that I wanted, but I would really appreciate some guidance, so it doesn't feel so hit and miss.
    (I have calibrated my monitor to 2.2 gamma 6500/D65 profile)
    Thank you,
    Keiko

    Keiko,
    One question at a time -
    "I read on GBallard that I should honor the source file's embedded profile.
    Yes. That means that when you open the tagged file (file with an embedded profile) you should have Photoshop either "Preserve the Embedded Profile" or "Convert to Working RGB." You set these in the Color Settings section where you should also check the boxes to have Photoshop prompt you for Profile Mismatches (the profile in the file is different from the Working Space that you have selected for Photoshop) when opening files and pasting and when opening files that have Missing Profiles.
    Photoshop is "honoring" the file's profile when it "Preserves" or when it "Converts." In either case, it uses the file's profile to accurately determine the actual colors in the file. The profile lets Photoshop reference the file's RGB values against an "absolute" color space called CIE Lab to arrive at an accurate understanding of the colors.
    When it "Preserves" the profile, it writes that profile back into the file when it Saves. When it "Converts" it writes its Working Space Profile into the file. Either way the color will be accurate. But I recommend Converting. That way a "standard color space" profile gets written into the file when you're done editing.
    "And that the file's source space should equal PS working space."
    No. You're misunderstanding something. The file's source color space is described by its profile. Read the above regarding Preserving or Converting the file's color space when bringing it into PS.
    Also, sRGB is the preferable space for both (am I wrong in that?). My main confusion is in trying to align the file and PS spaces. "
    No again. The file gets its original color space (created and assigned) by the device creating the file. That color space MAY be sRGB, or it may be some camera's proprietary profile.
    But, sRGB is a good space to use as Photoshop's Working Space if you are primarily working on images destined for the Web.
    Adobe RGB 1998 is also a good general purpose Working Space, especially if your images are going to be printed on a printing press. You can work in Adobe RGB 1998, then convert to sRGB before Saving for Web.
    Working spaces constrain the decisions PS must make in "mapping" (converting) color information from source space (a digital camera) to destination space (monitor, printer). Without Working Spaces, PS would need to give inordinate importance to colors far out of gamut for the destination space, to the detriment of accurate representation of "less exotic," more "important" colors.
    NEVER, NEVER, NEVER set Photoshop's Working Space to your monitor's profile. You may be able to get things set up so that you get consistent results looking at your images on your monitor, printing to your printer, but no one else will see the colors you "think" your images contain. Use Adobe RGB 1998, sRGB, ProPhoto RGB. These are all Device Independent spaces. Your monitor profile (color space) is unique to your monitor (Device Dependent).
    "-- Then -- what should my source space be?"
    Your Source Space is whatever profile your digital camera embeds in the file when it creates it.
    "my photo files are tagged Camera RGB."
    That's right.
    "Should I convert these files to the same space setting as the PS (such as sRGB)?
    Yes. See above.
    "I use images on both web and an epson R800."
    When you Save for Web you need to make sure you save the Web jpeg file in sRGB space, that is, Convert to sRGB as part of your workflow in Saving for Web. (You also should embed the sRGB profile in it. But the reality is that Web browsers, whether they understand ICC profiles or not, assume files are in sRGB space, whether they have an sRGB profile or not, and act accordingly on them)
    If your PS Working Space is sRGB and you Convert files you bring into Photoshop to sRGB on opening, then no further conversion is needed before Saving for Web.
    Whatever your PS working space, you will print to your Epson 800 through your Epson 800 ICC Printing Profile (either supplied as a "canned" profile from Epson, or a custom profile that you have generated or paid for through a profiling service). You let PS manage the color conversion involved in translating from its Working Space to the printer's Destination Space by selecting "Let Photoshop Determine Colors" under "File/Print With Preview/Color Management/Options.
    That's a lot of information. Please read it several times. But don't hesitate to ask if something doesn't seem to click.

  • SNAP profile automatically converts from ver. 4 to ver. 2

    As far as I know, I haven't updated my SNAP profiles for newsprint. I just exported an ad to my SNAP PDF preset and got this message: "Version 4 ICC Profiles were converted to version 2 ICC Profiles during PDF Export." My question is this: Is my PDF OK? I opened it and it looks okay. Printed it out and it looks OK. Never saw this warning before.
    I'll check my profiles to see if I downloaded and installed a profile I wasn't aware of. I do remember downloading some profiles to send to one of my freelancers so we'd have the same profiles. I'll check the SNAP website and download the most recent.
    We are all on CS4 mac platform if that's relevant.

    It is an odd message. I can get it if I export a doc with any SNAP profile assigned to PDF/X-1a—It happens with SNAP 2002, SNAP 2007, and SNAP 2009, but not with any other profiles I tried. It also seems to happen only with PDF/X-1a where there is an Output Intent included. If I choose PDF/X-1a and set the standard to None and don't include the Output Intent then I don't get the message. The Output Intent wouldn't affect the PDF numbers so I doesn't seem like a problem.

  • Assigning Profiles To Images

    I haven't found a way to assign a profile to an image in Aperture. Is this by design? An oversight? An ignorance of how to use Aperture on my part? I was expecting a command like the one in Preview where I can assign a profile, or convert to a profile. Thanks in advance, Michael

    Richard: Thank you for the pointer, it was helpful. Now I understand that Aperture doesn't expect us to assign or convert in Aperture, but only when we print or export. However, I have some slide scans that are unconverted—that is, just the raw data from the scanner. I also have some profiles for the scanner, and would like to assign them to the scan files. Must I do this in PS or Preview first? It seems like something I ought to be able to do in Aperture. Thanks again, Michael

  • Error while creating user - not authorized to assign profiles or roles

    I have configured CUA according to the help.sap.com instructions.  I am getting this error (in TCODE SCUL)..
    +You are not authorized to assign profiles
    Message no. 01589
    You are not authorized to assign profiles to users or to cancel the authorization.+
    I can create the user, change the address data, and initial password.
    I get errors on assigning to a group, parameters, or the role and profiles. 
    We are on NW Mobile 7.1 (ABAP stack only) SP05.
    I've read Note "492589 - CUA:  Minimum authorizations for communications users."
    It mentions SP07.  Is this not compatible?

    > Run SU53 (immediately after you receive the error message) and check which authorizations that failed. You probably miss S_USER_PRO with activity 01 or 02 from your own roles.
    I think that will not work in his situation. The errors show up in SCUL so they may come from one or more of the CUA children. Running SU53 in the CUA master will (if that is the case) not provide the necessary info.

  • The *.icc file is associated with PS process after assigning profile for a picture of CMYK mode ?

    Hi everyone, I have a curious problem for your help 
    My OS is Windows 7. Start PS and open an image, choose "Edit" -> "Assign Profile...", in the pop-up dialog there is a drop-down list showing many system profiles, and I find all of these *.icc files are stored in folder "C:\Windows\System32\spool\drivers\color". Just choose any profile to assign, then go to folder "C:\Windows\System32\spool\drivers\color" and find the related icc file, for example, JapanColor2001Coated.icc is for profile "Japan Color 2001 Coated". Now you can still rename the icc file, that is, the icc file is not taken by photoshop process. Our company has a software to generate icc files, however, when assign these profiles, the icc file is associated with PS process, which means I can't rename or delete the related icc file, even after assigning another profile, unless close the image documents, that is unwanted. So I'd like to know the reason, in fact I'm not very clear about the ICC file structure. I want to make the local disk file not associated with the process so I can do other operations.
    Any suggestion will be appreciated.

    I made a quick try and I can change the name of various custom profiles I've created using Photoshop but it appears that the name of the profile can't be changed if Photoshop was started with the profile in question selected as a soft proofing profile in View > Proof Setup. You have to quit Photoshop, just changing the soft proofing profile to another is not enough.

    Hi,
    I am having similar problems. I have read somewhere that png format can not handle CMYK colorspace anyway, which I find odd (and plainly stupid IM(NS)HO) which would mean that converting to RGB and therefore using profiles is mandatory.
    May be you should check if the internal format of the png files claims it is RGB or CMYK (using ImageMagick's "identify" command for example).

  • How do you assign profile in a format plugin read sequence

    I have a format plugin that will read various image formats.  I know what the source colorspace or profile  (i.e. ProPhoto RGB, sRGB, AdobeRGB, whatever) is.  I haven't figured out how to do the equivalent to Assign Profile from with my Read sequence in my Format Plugin.
    Surely there is a way to do this.  ACR does it.
    Any clues will be greatly appreciated!

    Well, it appears that you just fill in the iCCprofileData/iCCprofileSize fields with an ICC profile.
    You can read the ICC profile for a filter plugin and you can specify an ICC profile for a format plugin read sequence.

  • Problems with assign profile

    Hi,
    I want to make default an option "don't color manage this dokument".
    How can I do that?

    Unfortunately, it appears that you can't - at least not with the default interface.
    There is an option "Don't Color Manage this Document" in the Advanced section of the New... dialog window but unlike the other options there, this doesn't remain for the next time and reverts (defaults) to the profile selected for the Working Spaces in the Color Settings. The problem is that this options is not available in the profile menus of the Color Settings. I think you have a good case for a feature request - to include this option in the Working Spaces section of the Color Settings.
    Meanwhile, you can create an action by recording Edit > Assign Profile with the option Don't Color Manage This Document and use it with a hot key which you have to press each time after creating a new document and when you want to remove a profile.
    You can check what color profile an image has in the Info palette (F8). To display this information make sure it is checked in the Info palette's options accessible from its menu located at the top right on the palette.

  • Assigning profiles

    A lot of the threads in this forum seem to concern text-editing but in my job we have different priorities, namely prepress-concerns.
    Many of our customers work in obsolete color-spaces and anyway we often have to output for different print-conditions, so correcting the color-settings manually on numerous files can be somewhat boring
    So could any of You provide me with a clue concerning assigning profiles to a document with JavaScript?
    Thanks for any suggestions
    pfaffenbichler

    Found it:
    var myDocument = app.activeDocument;

  • Assigning Profiles in Illustrator CS5

    Hi Guys
    I have the issue when opening Illustrator documents containing images with different profiles, I have to decide on the assigning or converting for each image. Is there any global way within Illustrator to assign the working space of the document to all images?
    I know I can open the files individually in Photoshop, assign the correct profile then save the file and this will fix the problem, just wondered if there was a quicker way, as in InDesign.
    Many Thanks

    Hi Steve,
    If you would like to automatically assign Illustrator's working space to all incoming documents, go to Edit > Color Settings and do the following:
    1. Working Spaces: select the RGB and/or CMYK profiles that you would like all incoming RGB and CMYK images to be converted to.
    2. Color Management Policies: select "Convert to Working Space" for incoming RGB and CMYK documents, uncheck the "Ask when..." Profile mismatch and missing profile boxes.
    You may have to make sure the main document you're working in and importing files into is set to the working space profile for this to work.  New documents in Illustrator are by default set to the working space RGB or CMYK profile.
    The first imported image that contains a profile mismatch may still ask you once if you're sure you want to convert to the working space profile.  All following docs should no longer ask.  I think this is how Photoshop is set up, at least...

  • Monitor color profile - not converting sRGB to local color profile.

    I used Color Eyes Pro to color calibrate my monitor.
    When I view sRGB images in FF4, they don't display properly (not converting to my local color profile). Images I save as my local profile as imgs, appear fine in FF4. This applies to both JPGs and PNGs.
    IE and Chrome have no issues with view sRGB. Local color profile imgs of course appear correct.

    See https://developer.mozilla.org/En/ICC_color_correction_in_Firefox
    Caveats: The new QCMS color management system introduced in Firefox 3.5 currently only supports ICC version 2 color profiles, not version 4.

  • Error -25923 assigning profile

    My automate plugin assigns a profile by playing "assignProfile" on the current document with a named "profile" parameter. This has worked fine in CS4, CS3 and earlier. But now in CS5 it fails whenever there is already a profile assigned to the document. (If there is no profile already assigned then there is no problem)
    I have tried various workarounds, like clearing the existing profile first, setting the working profile first, assigning the profile more than once, even clearing the profile first by playing a recorded action. Nothing seems to work.
    Has anyone else seen this or have any advice? Has anything changed in the implementation that I need to be aware of?
    Tom

    My original description of the problem was not quite correct. Seems the issue is that CS5 is not aware of my profile.
    Before assigning a profile CS5 now checks that it is in a cached list of profiles and errors if it is not. CS4 and earlier never did this. CS5 only updates its list when either 1) the GUI is shown or 2) (if the cache is not yet built) the first time the assignProfile action is executed.
    My plugin creates a new profile (potentially a different one each time) and puts it in ~/Library/ColorSync/Profiles/ and therefore it's not in the cached list. The reason I thought it had something to do with a profile already being assigned was that the first time I execute the action it always tended to succeed (because of 2.)
    I'm still stuck of course.
