Color-managed system suddenly went haywire!

THE PROBLEM
I had everything working smoothly on my system so that I was getting fairly accurate colors when saving sRGB images for web display. Then I had to go away for the weekend and took my MacBook pro with me. I was working a bit in Photoshop on it, but did not change any settings. When I got back to my office and external display, I was surprised to find that all of my images inexplicably look much darker and grossly over-saturated when viewed in any web browser or in Preview. This is the case with any image I've ever made in Photoshop. They all still look fine inside Photoshop, though.
MY ATTEMPTS AT A FIX
So I thought maybe something had gone wrong with my monitor profile. I immediately recalibrated my external display (an IPS panel, with my EyeOne Display2, using ColorEyes software). It didn't help. All sRGB images still look really dark and highly saturated. Here is an example (the one on the left is opened in Photoshop).
Whatever has gone wrong? Why the sudden change, and how do I get back to having RGB images look right outside of Photoshop?

>> although none of the profiles I can select are any of the ones I've created recently with my normal user login). So what does this mean, and how do I go about fixing it?
Two things:
First. if the custom profiles are the problem (as Chris suspects) and you haven't loaded them in the new user — that points pretty straight to the problem — either add one of the suspect profiles into the new account (set it as monitor RGB in System Preferences> Displays>Color: Display Profile) or take the custom profile out of the old account by setting a canned generic sRGB profile there as your monitor profile (and rebooting).
Second, I don't see the point of an Archive Install at this point especially if a New Account doesn't have the problem — you would still be stuck with a defective profiling package at the end of the process (if that's the problem).
If the custom profiles are "the switch" you need to look there at updating your profiling software or replacing your defective instrument...

  • Error Message:Can't print illustration. Color Management systems inconsistent.

    I am getting this error message, "Can't print illustration. Color management systems are inconsistent." I just upgraded to CS5(from CS2) on a Dell Studio using an Epson WorkForce 1100 or an Epson Sylus NX400. I am a rank amateur in AI & have no idea how to fix this. I do not seem to have the option to turn off color management in either of my printers to default to AI. All I am trying to print are some labels using regular fonts and a few smoke brushes for color. These are not wildly colorful or complicated. I KNOW I should be using a Mac but I do not have one...sigh...

  • Computer suddenly went haywire

    My computer SEEMS to be okay now, but I would an explanation of what went wrong, so that I'll be prepared next time, or to make sure that there is no next time.
    I have never had a problem like this. Here's the story. One day everything worked flawlessly, the next time I tried to use it, it was a total mess. I won't detail all of the problems, but the first one is that the password box kept filling the entire space automatically, and I couldn't delete the characters to type in the correct password. All that happened between the two times was that I was carrying the computer in my car for safekeeping. I didn't drop it. It didn't get exposed to heat. No water touched it, etc. The only thing that might have happened, although I don't know why, is that I may have not properly turned the machine off. It therefore could have exhausted the battery charge overnight. However, the computer still wouldn't work even after I plugged it into the wall. Shouldn't the computer run if it's plugged in even if the battery is dead? Anyway, after deciding to take my computer to the shop for repair, I left it plugged in for several more hours, and it then worked. Is this to be expected? Isn't the wall current sufficient to run the machine even if the battery is dead?

    Hello,
    It sounds like you are describing that a key was stuck down on your keyboard. That would explain why the password dialog kept filling without you typing. Check your keyboard to see if any of the keys are sticking.
    The previous author was suggesting that you use the Disk Utility program. Form the Disk Utility window, select your disk, probably, "Macintosh HD." From the tabs on the right, select First Aid. Under First Aid, select Repair Disk Permissions.
    Some apparently random problems are caused when the operating system does not have permission to modify or open certain files it needs. The file permissions can be left in an incorrect state by an unexpected shutdown due to a dead battery or a system crash.
    Good luck with your problem.

  • Confused about Color Management in CS5 (Photos appearing differently in all other programs)

    I recently noticed this and it's been driving me crazy; when I view photos in Photoshop CS5 they appear significantly lighter/more washed out than when viewed in other programs like Zoombrowser, Digital Photo Professional or just in a regular Windows folder using Filmstrip mode (Windows XP).  When opening the same photo in both CS5 and Zoombrowser and switching back and forth between the two windows the difference is very apparent...for example, one of the photos I compared was of a person in a black shirt -- in CS5 (lighter/washed out) the folds in the shirt were very obvious, but in Zoombrowser (darker, more contrast/saturation) the folds were nearly invisible and it looked like just solid black.  Now, after messing around with the settings in both Photoshop and in Zoombrowser I've found a few ways to get the photos to look the same in the two programs; one way gives them both the lighter/more washed out appearance and another way gives them both the darker appearance with more contrast and saturation.  My problem is that I'm not sure which view is accurate.
    I use a NEC MultiSync LCD1990SXi monitor with SpectraView II calibration software and calibrate it every 2 weeks using these calibration settings (screenshot): http://img52.imageshack.us/img52/8826/settingsx.jpg
    In the SpectraView II Software under Preferences there's an option that says "Set as Windows Color Management System Monitor Profile - Automatically selects and associates the generated ICC monitor profile with the Color Management System (CMS)."  This option is checked.  Also, when I open the Windows' Color Management window there's only one option displayed, which is "LCD1990SXi #######" (the ####### represents my monitor's serial number).
    I assume the above settings are all correct so far, but I'm not sure about the rest.
    Here are my current default Color Settings in CS5 (screenshot): http://img97.imageshack.us/img97/666/photoshopcolorsettings.jpg
    Changing these settings around doesn't seem to make the photo appear much different.  However, when I go to Edit -> Assign Profile, then click off of "Working RGB: sRGB IEC61966-2.1" and instead click Profile and select "LCD1990SXi ####### 2011-06-21 18-30 D65 2.20" from the drop-down menu, the picture becomes darker with more contrast and saturation and matches the picture in Zoombrowser.  Also, if I select "Adobe RGB (1998)" from the drop-down menu it's very similar in terms of increased darkness and contrast but the saturation is higher than with the LCD1990SXi setting.  Another way I've found to make the image equally dark with increased contrast and saturation is to go to View -> Proof Setup -> Custom and then click the drop-down menu next to "Device to Simulate" and select "LCD1990SXi ####### 2011-06-21 18-30 D65 2.20" again.
    Alternatively, to make both images equally light and washed out I can go to Zoombrowser -> Tools -> Preferences and check the box next to "Color Management: Adjust colors of images using monitor profile."  This makes the image in Zoombrowser appear just like it does in CS5 by default.
    Like I said, I'm confused as to which setting is the accurate one (I'm new to Color Management in general so I apologize for my ignorance on the subject).
    It would seem that assigning the LCD1990SXi profile in CS5 would be the correct choice in order to match the monitor calibration given the name of the profile but the "Adjust colors of images using monitor profile" option in Zoombrowser sounds like it would do the same thing as well.  Also, I've read that Photoshop is a color managed software whereas Zoombrowser and Windows Picture and Fax Viewer are not which makes me think that maybe the lighter/washed out version seen in Photoshop is correct.  So which version (light or dark) is the accurate one that I should use to view and edit my photos?  Thanks in advance for any help or info.

    Sorry for the late reply;
    But before we go there or make any assumptions, it's important for
    you to determine whether you're seeing consistent color in your
    color-managed applications and only inconsistent color in those that are
    not color-managed.  For that you'll need to do a little research to see
    if the applications in which you're seeing darker colors have
    color-management capability (and whether it is enabled).
    I opened the same picture in 7 different applications and found that the 6 of the 7 displayed the photo equally dark with equally high contrast when compared to the 7th application (CS5).  The other 6 applications were Zoombrowser EX, Digital Photo Professional, Windows Picture and Fax Viewer, Quicktime PictureViewer, Microsoft Office Picture Manager and Firefox.
    However, at least two of these programs offer color management preferences and, when used, display the photo (from what I can tell) exactly the same as Photoshop CS5's default settings.  The two programs are two Canon programs: Zoombrowser EX and Digital Photo Professional.  Here's the setting that needs to be selected in Zoombrowser in order to match up with CS5 (circled in red):
    And here's the setting in Digital Photo Professional that needs to be selected in order to match up with CS5 (again, circled in red):
    *Note: When the option above "Monitor Profile" is selected ("Use the OS settings") the image is displayed exactly the same as when the monitor profile is selected.  It's only when sRGB is selected that it goes back to the default darker, more contrasty version.
    So with the red-circled options selected, all three programs (CS5, ZB, DPP) display the images the same way; lighter and more washed out.  What I'm still having trouble understanding is if that ligher, more washed out display is the accurate one or not...I've read several tutorials for all three programs which only make things more confusing.  One of the tutorials says to always use sRGB if you want accurate results and *never* to use Monitor Profile and another says that, if you're using a calibrated monitor, you should always select Monitor Profile under the color management settings...so I'm still lost, unfortunately.
    What I also don't understand is why, when the monitor profile is selected in CS5, the image is displayed in the dark and contrasty way that the other programs display it as by default but when the monitor profile is selected in Digitial Photo Professional it displays it in the lighter, more washed out way that CS5 displays it using CS5's default settings (sRGB).  Why would selecting the monitor profile in DPP display the photo the same way as when sRGB is selected in Photoshop?  And vice versa...why would selecting the monitor profile in Photoshop display the photo the same way as when sRGB is selected in DPP?
    I feel like I'm missing something obvious here...which I probably am.  Again, I'm very new to this stuff so pardon my ignorance on the topic.
    By the way, I find that the way that the non-color managed programs (Windows Picture and Fax Viewer et al.) display the photos is more aesthetically pleasing to the eye than the duller, more washed out display that CS5 gives the photos, but ultimately what I want to see in these programs (especially PS5 where I'll be doing the editing) is the accurate representation of the actual photo itself...i.e. what it's supposed to look like and not a darker (or lighter) variant of it.
    So just to reiterate my questions:
    Why does selecting Monitor Profile under the color management settings in DPP give the same display results as the default sRGB profile in CS5 and vice versa?  (CS5 with monitor profile selected having the same display results as DPP with the sRGB profile selected)
    When using CS5 with it's default color management settings (sRGB), using DPP with the Monitor Profile selected, and using Zoombrowser EX with "Adjust color of images using monitor profile" selected this results in all three programs displaying the same lighter, washed-out images...is this lighter, more washed-out display of the images shown in these three programs the accurate one?
    I noticed when opening an image in Firefox it had the same darker, contrasty look as the other non-color managed applications had.  Assuming that the CS5 default settings are accurate, does this mean that if I edit a photo in CS5, save it, and upload it to the internet that other people who are viewing that image online will see it differently than how it's supposed to look (i.e. in a non-color-managed way?)  If so, this would seem to indicate that they'd see a less-than-flattering version of the photo since if their browser naturally displays images as darker and more contrasty and I added more darkness and contrast to the image in CS5, they'd be seeing a version of the photo that's far too dark and probably wouldn't look very good.  Is this something I have to worry about as well?
    I apologize for the lengthy post; I do tend to be a bit OCD about these things...it's a habit I picked up once I realized I'd been improperly editing photos on an  incorrectly calibrated monitor for years and all that time and effort had been spent editing photos in a certain way that looked good on my incorrectly calibrated monitor but looked like crap on everyone else's screen, so the length and detail of this post comes from a desire to not repeat similar mistakes by editing photos the wrong way all over again.  Again, thanks in advance for all the help, it's greatly appreciated!

  • Color management issue from Photoshop Acrobat

    I'm having an issue that I believe has been isolated to Acrobat X related to Color Management, but was referred to this Photoshop forum because more experts in color management tend to read here. My thread in the Acrobat forum with several updates on tests is here: http://forums.adobe.com/message/4646650#4646650
    The short version is that any RGB image I create in any app (including Photoshop, Illustrator, and InDesign, a non-Adobe app with Word, and Acrobat's own PDF from Screen Capture feature) displays in both Acrobat X and Adobe Reader with dull colors, very similar (if not identical) to how an RGB file with full intensity colors (i.e. R255 or G255) looks when converted to CMYK.
    I've tried numerous settings in the Color Management system, and have Synchronized my Color Settings via Bridge across all Adobe CS6 apps. I've tried synchronizing to both the default North American General Purpose 2, and the (sometimes suggested) Monitor Color, using a calibrated profile for my Dell display from OS X's built-in tool. Have also tried various settings of Preserving Embedded Profiles, ignoring them, Assigning a new Color Profile to a document, turning off color management completely, etc. No change in result.
    I have a multi-monitor setup (3 external Dell displays connected to a Macbook Pro, 2 of them via USB video devices), but I've also tried making each display (including the laptop's built-in display) my Primary monitor and can see the color shift on each one, so it doesn't appear to be a calibration issue.
    This issue is on my Mac at the office. I have a similar setup at home (albeit a MacPro 1,1 vs. a laptop) but with the same Dell monitors and CS6 software installation, and I can take the same document (whether it's InDesign, Illustrator, or Photoshop), make a PDF of it, and it displays with 100% accurate colors when viewed in Acrobat X.
    In addition to the tests mentioned in my original thread, I've also tried uninstalling and reinstalling both Acrobat X and Adobe Reader.
    I believe the issue is related to Acrobat, as I can repeat the issue with no other apps than Acrobat in the workflow: if I display a full-intensity RGB image on screen, then use Acrobat X to create a PDF from Screen Capture, the resulting PDF immediately shifts to the dull colors.
    Have also thoroughly checked through Acrobat's preferences, as it seems almost as if there's a setting somewhere along the lines of "View all PDFs in CMYK color gamut", but no such setting exists. I did a complete uninstall of Acrobat X as well, which I imagine would also dump its Preferences, so it would be a clean reinstall.
    Another interesting note: Apple's Preview app seems to display the PDF with accurate RGB colors, so I know the PDF actually has the correct color definitions intact. But the same PDF opened in Acrobat X or Reader side-by-side displays the dull colors.
    Any thoughts?
    -R

    i wasn't able to follow your lengthy post, and the color management chain is too complicated (for me) to address here other to say Acrobat reads tagged elements and converts their colors to Monitor RGB (so you must have stripped the profiles in the PDF, and the Acrobat CMS is applying or passing through the wrong profile)
    further, if you don't want to rely on profiles, your safest bet (for screen viewing) is to CONVERT everything to sRGB (but i would still include the profile in case someone wants to display or print the document 'accurately'
    Here is a look at a several critical color setting in Export to Acrobat that control: Downsampling, Compression, Color Conversions, Destination, and Tagging (click on image for blowup):
    PS:
    these panels were grabbed from an InDesign Export PDF process, but Photoshop should have similar options somewhere

  • Color Management on a Photosmart 510a

    I have the Color Munki color management system.  It asks me to "disconnect" the color management in my Photosmart 510a.
    Have NO clue as to where to do that.  Is it by just changing the option to have the "software manage the colors?"
    Thanks for info.
    Bert

    So what you're saying, which is not expressed very well in the very first post in the thread, is that for files saved WITH the sRGB profile, you'd like to see the same thing in Photoshop as you're seeing in a color-managed browser.  What I can't fathom why you would want to save files with no embedded profile.  Let's make that a separate discussion.
    Going on the assumption above, and that you're using Windows 7, here's what you need to do:
    1.  Your monitor profile (i.e., the one created by your calibrator or which came with your monitor) should be your default profile in Windows.  To check this, click the Start button, and type color management into the search box.  When Color Management comes up, click it, and look in the Advanced tab.
    2.  Photoshop's color management should be enabled, and View - Proof Colors menu should be UNchecked.  This means Photoshop will transform the RGB values in an image with a given image profile into the proper values for correct display on your monitor.  This is your normal mode for editing.
    3.  Create your web image using the sRGB color profile as your working space.
    4.  Save it with the sRGB color profile embedded.
    5.  Display it in Firefox.  It should look just the same as it did in Photoshop.
    6.  Capture the screen showing both images (Photoshop and Firefox) side by side.
    7.  Paste the captured image into a new document in Photoshop, and ASSIGN your monitor profile to it (because you grabbed it from your monitor).  If you have the proper checkbox set in your color management settings, Photoshop will automatically ask you to make this choice when you're pasting the image.  It should look just as it did when you captured it.
    8.  CONVERT the image to the sRGB color profile.  You should not see the appearance of the image change.
    9.  Save this image to a file, complete with the sRGB color profile.
    10.  Post the image here.
    Let me know if anything's not clear, or something doesn't happen as expected.

  • Color management help needed for adobe CS5 and Epson printer 1400-Prints coming out too dark with re

    Color management help needed for adobe CS5 and Epson printer 1400-Prints coming out too dark with reddish cast and loss of detail
    System: Windows 7
    Adobe CS5
    Printer: Epson Stylus Photo 1400
    Paper: Inkjet matte presentation paper with slight luster
    Installed latest patch for Adobe CS5
    Epson driver up to date
    After reading solutions online and trying them for my settings for 2 days I am still unable to print what I am seeing on my screen in Adobe CS5. I calibrated my monitor, but am not sure once calibration is saved if I somehow use this setting in Photoshop’s color management.
    The files I am printing are photographs of dogs with lots of detail  I digitally painted with my Wacom tablet in Photoshop CS5 and then printed with Epson Stylus 1400 on inkjet paper 20lb with slight luster.
    My Printed images lose a lot of the detail & come out way to dark with a reddish cast and loss of detail when I used these settings in the printing window:
    Color Handling: Photoshop manages color, Color management -ICM, OFF no color adjustment.
    When I change to these settings in printer window: Color Handling:  Printer manages color.  Color management- Color Controls, 1.8 Gamma and choose Epson Standard it prints lighter, but with reddish cast and very little detail and this is the best setting I have used so far.
    Based on what I have read on line, I think the issue is mainly to do with what controls are set in the Photoshop Color Settings window and the Epson Printer preferences. I have screen images attached of these windows and would appreciate knowing what you recommend I enter for each choice.
    Also I am confused as to what ICM color management system to use with this printer and CS5:
    What is the best ICM to use with PS CS5 & the Epson 1400 printer? Should I use the same ICM for both?
    Do I embed the ICM I choose into the new files I create? 
    Do I view all files in the CS5 workspace in this default ICM?
    Do I set my monitor setting to the same ICM?
    If new file opens in CS5 workspace and it has a different embedded profile than my workspace, do I convert it?
    Do I set my printer, Monitor and PS CS5 color settings to the same ICM?
    Is using the same ICM for all devices what is called a consistent workflow?
    I appreciate any and all advice that can be sent my way on this complicated issue. Thank you in advance for your time and kind help.

  • Printing, Soft Proofing & Color Management in LR 1.2: Two Questions

    Printing, Soft Proofing, and Color Management in LR 1.2: Two Questions
    There are 2 common ways to set color management in Adobe CS2:
    1. use managed by printer setting or,
    2. use managed by Adobe CS2 program.
    I want to ask how Color Management for Adobe LR 1.2 differs from that in CS2?
    As is well known, Color Management by printer requires accurate printer profiles including specific model printer, types of ink and specific paper. It is clear that this seems to work well for LR 1.2 when using the Printer module.
    Now lets consider what happens one tries to use Color Management by Adobe LR 1.2. Again, as is well known, Color Management by printer must be turned off so that only one Color Management system is used. It has been my experience that LR 1.2 cant Color Manage my images correctly. Perhaps someone with more experience can state whether this is true or what I might be doing to invalidate LR 1.2 Color Management.
    Specifically, I cant use Soft Proofing to see how my images are changed on my monitor when I try to use the edit functions in LR 1.2. Martin Evening states in his text, The Adobe Photoshop Lightroom Book that it is not possible to display the results of the rendered choices (Perceptual or Relative) on the display monitor. While it is not clear in Evenings text if this applies to LR 1.2, my experience would suggest that it still applies to the 1.2 update even though the publication date of his book preceded this update.
    Can someone with specific knowledge of Adobe LR 1.2 confirm that Color Management and Soft Proofing with LR 1.2 hasnt been implemented at the present.
    The writer is a retired physicist with experience in laser physics and quantum optics.
    Thanks,
    Hersch Pilloff

    Hersch,
    since just like me, you're a physicist (I am just a little further from retirement ;) ) I'll explain a little further. computer screens (whether they are CRT or LCD) are based on emission (or transmission) of three colors of light in specific (but different for every screen) shades of red, green, and blue. This light stimulates the receptors in your eye which are sensitive to certain but different bands of red, green and blue as the display emits, making your brain think it sees a certain color instead of a mix of red green and blue. Printers however, produce color by modifying the reflection of the paper by absorbing light. Their color mixing operates completely differently than displays. When you throw all colors of ink on the paper, you get black (the mixing is said to be subtractive) instead of white as you get in displays (the mixing there is additive). The consequence of this is that in the absence of an infinite number of inks you cannot produce all the colors you can display on a monitor using a printer and vice versa. This can be easily seen if you compare a display's profile to a printer profile in a program such as Colorsync utility (on every mac) or
    Gamut vision. Typically printers cannot reproduce a very large region in the blue but most displays on the other hand cannot make saturated yellows and cyans.
    Here is a flattened XY diagram of a few color spaces and a typical printer profile to illustrate this. Most displays are close to sRGB, but some expensive ones are close to adobeRGB, making the possible difference between print and screen even worse.
    So, when the conversion to the printer's profile is made from your source file (which in Lightroom is in a variant of prophotoRGB), for a lot of colors, the color management routine in the computer software has to make an approximation (the choice of perceptual and relative colorimetric determine what sort of approximation is made). Soft proofing allows you to see the result of this approximation and to correct specific problems with it.

  • Major Bug in CS's color profiles, color management & working spaces

    Hi everyone:
    First of all, thanks so much for taking the time to read and answer my questions!!! I am having a having a major bug in CS3's creative suite. The problem is the following:
    1. My settings are not sticking in Photoshop. Last night I selected Adobe RGB as my working space and this morning I woke up with it being Apple RGB.
    2. Bridge. When I select one of the thumbnails of my edited files I see the colors and levels changing before my very eyes. My theory is that profiles are being assigned to the images as I select them.
    3. Photoshop. Photoshop is assigning embedded profiles (of whatever working space is selected) into my files. I have the color management system on off so this should not be happening.
    The only solutions that I came up with were to either uninstall and reinstall creative suite or upgrade to CS4. Does anyone have any other suggestions out there? I would greatly appreciate them.
    All my best,
    s_ke

    Ok open Edit > Color Settings. Where it says "color management policies" make sure that all these are set to "preserve"
    • You seem to be saying that photoshop is automatically converting images, without opening them? -  this is impossible
    • Document profiles are readable at the bottom of the image window and choosing 'document profile'
    If something strange is happening reset your Preferences, you will not need to reinstall
    It may also be that your issue is to do with monitor profiles, or something similar but its impossible to tell from your description

  • Does Firefox 3.5 support only some ICC profiles (AdobeRGB, sRGB, e.g.) or all ICC profiles in color management?

    I put one image embedded with a ICC profile with D65 as white point, and the same image embedded with another ICC profile but with D50 as white point (the 'chad' matrix in the profile is different as well, given different white point for two profiles). When these two images (of same RGB values) but with different ICC profiles embedded are displayed side-by-side in Firefox, difference in color should be noticed between two images if color management is available in Firefox (color management is turned on in about:config). However, I did not see any difference.
    I tried using the same image but embedded one with sRGB profile, and the other with AdobeRGB profile. Now I can see the difference.
    So my question is whether Firefox can only recognize a certain number of ICC profiles but not all of them.
    Thanks.

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

  • Color management - Indesign with PS calibrated images?

    How to:
    In PS  CMYK color space  looks great using laser printer. Printer and monitor are calibrated - so what you see is what you get - but only in PS.
    When the images are imported to Indesign or  or converted to a PDF the colors look awful, dirty, with cast.

    Any help would be great. Thanks.

    >> In PS  CMYK color space  looks great using laser printer. Printer and monitor are calibrated - so what you see is what you get
    Photoshop (Ps) is apparently making a good Conversion to your Print Space-Profile (or you are getting lucky they are close).

    Establish device-independent 'native' Color Spaces (Working RGB and CMYK) and CONVERT to your PROOFING (print/monitor/Web) ICC profiles as a last step in the printing process and/or Saving a production copy in the target color space.
    >> Should color space be changed even though is all printed on same CMYK laser printer.
    Your Source Spaces will typically be different than your Print Space and your Monitor Space and your Web Space — CMYK is different in that it may be also be both Source/Target spaces — I create/work/edit in high-bit, high-gamut RGB and CONVERT to CMYK in the Printer Utility or in a final production copy when I know the target CMYK profile.

  • Image Color management in Firefox 4 is off

    I recently upgraded to FF4. Prior to that I had excellent color agreement in the 3 browsers I use to check the websites I design. Now the color in FF4 is way, WAY, OFF.
    I use srgb tagged images and a calibrated monitor and the colors are correct in Chrome, IE8 AND in FF 3.63 but NOT in FF 4. I just spent about an hour trying to figure out why an image on a website I designed no longer matched its background when neither the image, the background nor anything else about the page had changed in a month. Turns out the only thing that changed was the browser! This is NOT GOOD.

    You can set the pref gfx.color_management.mode to 0 on the about:config page to disable Color Management in Firefox. You need to close and restart Firefox to make the change effective.<br />

    Caveats: The new QCMS color management system introduced in Firefox 3.5 currently only supports ICC version 2 color profiles, not version 4.

  • Print Color Management Problem ?

    I have a print color management problem I cannot solve. It reminds me of the print color management problem I had over a year ago when the compatibility conflict between LR and MAC Leopard produced horrible prints. I have Snow Leopard now and been out of the country for some months and yesterday when I tried to make some prints the same problem reemerged. So I downloaded current drivers (and ICCsfor Premium Luster) from Epson and LR 2.6 and spent a good part of the day with Martin Evening's book. I followed (I think) his instructions to make the basic print step by step but the prints still were terrible. My problem is with the color management pop up in the print settings dialog -- it says "color matching" not color management and I cannot check either "no color management " if I want LR to control the process (Kelby)  or check "color sync" if I want my Epson R800 take over. I have no idea where the "color management" pop up went. I'm clueless as usual and probably omitting a step because of frustration or brain numbness. Any help would be appreciated. WJS

    The settings in Lightroom are simple. and contain in the Print Job panel in the Print module. You either select manage in printer (and then select the profile in the printer drivers) or select the profile here and then turn of all colour management in the printer drivers. The second option will usually produce the best results. What you don't want is to have the profile selected in both LR and the printer drivers, so if the driver doesn't have an option to turn of colour management then you may be forced down the first route. However it would be an unusual decision for a printer manufacturer to make drivers that can't turn off colour management, so you may wish to ask how to do it to your printer manufacturer or check the printers handbook.

  • Color management book recommendation?

    Hi folks,
    I've been using Photoshop since version 2, but only as a violinist might relax with a bit of keyboard playing.  My main gig over the years has been multimedia programming and 3D animation, both for onscreen delivery in the wonderfully sane world of RGB color.
    I now have to turn to print in a big way, and to difficult print at that.  I have to create a book cover for a print-on-demand job a Lightning Source.  The image has lots of contrast, and LS imposes a no-more-than-240% ink coverage limit in CMYK, which means I'm going to have to massage the dark areas of the image without destroying the beautiful color tonalities of the front cover painting.
    So color management is suddenly mission critical, and I'd like to dip my head in the theory in a serious way.  If any of you print jockeys could recommend a source on the subject, I'd be grateful.  I know Adobe Community Help has videos and article references, and I will peruse them gladly.  But what I am looking for is a definitive theoretical groundwork text – something like an O'Reilly book on color management for print media that I can sit down and read cover to cover.
    Many thanks,

    s-RGB="Satan RGB" I didn't want to mention this in the string because....... As mama used to say "Don't  frighten the horses."
    The s-RGB gamut is so small and incompatible with traditional CMYK that clipping and shifting is a given.....hence the heavy use of  GCR (grey component replacement) and UCR (under color removal) in the printing. GCR is the enemy of the type of rich saturation that we see in this woman's portrait, but complex browns, purples, greens, and reds are very easily changed with even the slightest inattention or miscalibration during a typical press run (Forget about the blues). Swapping out the pigments with neutrals is designed to protect one's image from colorshifting as the inks get slabbered onto the paper. That is why finding a reliable and competent printer is such an important part of the process. Unfortunately, they are a dying breed. Also, sadly, even if one carefully manages the GCR and the UCR (to remove the extra saturation as this "Lightning" place is suggesting is really no guarantee that their print settings (PPDs) will not ovverride even the PDF file itself when they rip it.
    That is the reason I suggested the importance of finding a reliable print house or else just making one's file "photo perfect" (without trying to accommodate the print house and then force the printer to reproduce a quality rendition at the proof stage. It is like playing pool on a moving train...all about relativity. Hence my caveat.
    Your adjustment looks great....looking at the pdf of your curve adjustments, by the way. Still the presses haven't had their way with her yet. And that is the endgame. If we did not have to farm stuff out we could set our GCR and UCR in Photoshop along with our calibration process built to our own press specifications and forget about it. But the inmates do run the asylum. There I go, scaring the horses.
    Something I remembered. A conversation with Bruce and Russell P.Brown (1997?) whom, if I remember correctly had some powerful new toys (Gee, how did he get a hold of THAT stuff???? LOL) One of his projects had to do with scanning the environment (my term for it) and he had images that were plotted at full size on a large plotter (Not QUITE the Grand Canyon but HUGE). The discussion/debate revolved around Russell's ability to reproduce the image without swapping the format and/or geeking with the gamut problems inherent in CMYK conversion. I didn't get it, really, and I do not think that Bruce got it...well let us say he was openly dubious...still Russell's very large printout was spectacular and Russell, being Russell was too excited to give a pixel. Late night standoff! Walking away, I realized that with newer pigments that were available from the digital printing world, I would have to stay on my toes when it  came to discussing any print end format because the traditional CMYK printing inks were being seriously upgraded with the newer electrostatic and gelatin print technologies. (especially with Kodak and Agfa being such big players with the Creo purchase of Scitex and Agfa being Agfa). It seems now that we are in a whole new world and I am loathe to proclaim the ancient truths of CMYK as we traditional printers knew it.  I have seen some work coming off of these newer printers that transcend the CMYK gamut. (It is interesting to think that the age of "cold type printing" lasted about twenty years before it began to be obsolete. One of the bonus points of geezerism (if I may use the term loosely) is the perspective of time warp speed of tech obsolescence. It seems sometimes that halfway through an answer to any given question the answer becomes quaintly out of date.
    I can say that any equation depends on isolating  the variables and finding those constants that will endure. Best example..... the half-life of Adobe 1998 as a transcendent color space. I am now convinced that ProPhoto has a fuller and more malleable gamut for the newer devices as well as the offset presses that will be with us for a while longer.
    So I guess, my point is that one has to plant the flag somewhere. Pick any locus and relate to that to build one's foundation (s-RGB or 72 ppi for example) and know that in the shifting sands of a million minds, there will be hordes of wild indians waiting to excoriate the status quo without understanding the very underpinnings of the process.
    One thing I have noticed in the fora is the very  vituperation is inversely proportional to one's experience. That is one of the ways that people like Mssrs. Fraser, Brown, McClelland, and even you stand out. The dialog is temperate yet radically outrageous. I am not sure sometimes if the science has not turned to theatre. Hah!
    I rant, but towards a point that recedes as I approach it.
    Namely this:
    be forgiving towards the quirks and kinks in the Adobe approach, the product, as does all revolutions, breeds evolution. Though each of their programs converts your average PANTONE color with a different ink percentage.
    One does appreciate an open mind. Thanks for that.
