Colorsync native profile mystery

When you calibrate your display using Colorsync calibration (the 5 steps), OS X will create a tailor made colour profile for your display. This calibrated profile is unique to your display.
So how come photo's viewed using this profile appear identical (in terms of colour) to the "default" profiles:
Adobe RGB (1998)
Apple RGB
Colormatch RGB
NTSC 1953
SMPTE-C
Those profiles ship with OS X, the probability that your unique display calibration is identical to one of those profiles is a million to one. Let alone all profiles. I have tested this on 3 macs. Everytime you paintstakingly calibrate the display using the sliders on colorsync calibration, you finish, select a default profile and it's identical to your calibrated one.
Why?
PS: I always select use native gamma, does it have something to do with that? (but gamma is brightness, the colours should still not come out identical?) Is native gamma the best choice?

Exception while calling native profiler (root cause: no message available [

Hi,
We are setting up MAM30 using the new technology (NWMADMIN). During sync. I get the error message "Exception while calling native profiler (root cause: no message available [java.lang.reflect.Invocat...". Can anyone help me on this?
Thanks
Kind regards
Jacob

Hi Jacob,
I once faced this problem(no in MAM though)
I will try to guess the solution to your problem,
1) My first guess would be that, the header file in MAM30 using the 'javah' tool, did not pass the fully qualified name of the class as the argument. The 'javah' tool will not complain and will produce an incorrect header file.
2) The Native method names wouldnt have got a match for the java method names, might be missing the package name. here you need to import the missing ones.
3) Or you would be calling static native methods using objects, it should be accessed in a static way. you can call them directly.
Hope this helps.

Divya.

When I use the new ColorSync icc Profile!

Wwhen I use the new ColorSync icc Profile!
the New Settings will be reset to Default Profile

The Critical Problem was solved by buying a Apple DisplayPort VGA Cable[New Taiwan Dollar :1,000]
link http://store.apple.com/us/product/MB572Z/A?fnode=MTY1NDA3Ng&mco=MTA4NDU0NjA
The Fact is that the Mac mini Bundled HDMI to DVI would made my ColorSync Profile to Default everytime I
Reboot or logout my mac mini.
Also, if you Rrealize the boot-up mac mini Superdrive DVD is noisy! You could just insert a DVD inside, then When you boot-up your Mac mini next time, the noise is Vanished ^^ & Happy
So, Apple just accept its made Display Protocol for ColorSync to Adjust the Monitor Color, befroe I`ve done this,
I thought I have to buy a Apple Cinema Display or Macbook, then I can Get that kind of Benefits!
But Hopefully, My problem is just solved & Happy .

Agfa ScanWise cannot find Colorsync System Profile

Another casualty in Snow Leopard. My Agfa Scanner uses Scanwise 2.1fc2 (the last from Agfa). It worked OK in Leopard.
Now when it starts I get" ScanWise can not find the current ColorSync System Profile. Please recalibrate your monitor or select another system profile with the ColorSync Control Panel".

Here's exactly what I did to get TWAIN SANE Interface to work:
--Go to TWAIN SANE Interface site: http://www.ellert.se/twain-sane/
--Download the (1) libusb, (2) SANE backends, (3) SANE preference pane, (4) TWAIN SANE interface binary packages for Snow Leopard
--Grab the FAQ on that page too (http://www.ellert.se/twain-sane/faq.html)
--Install the packages in the order above just by double-clicking them
--Open the FAQ file and read it!
--Launch the Terminal, and type the following to scan: scanimage --format tiff > test.tiff
--A tiff file of your document will be scanned and stored in your Home folder
According to the page, you should be able to get your scanner to work within Word, Graphic Converter, etc., but I haven't figured that out yet. For now, I'm just happy that I can scan again. Nice to know that something like the SANE project is out there...

Odd colorsync monitor profile issue

Hi all
I have my monitor calibrated and its profile is selected in two separate accounts on my Mac. When I start up the Mac and log in to either account on its own all is fine. However as soon as both accounts are logged in then the monitor profile defaults to the Generic RGB profile and if I go to the display preferences I am unable to change the profile, I just get beeps every time I click on any profile in the list. Also if I go into the Colorsync Utility my Display is no longer listed in the Device - Displays list to the left, it is in there after a restart.
This is getting very annoying because I do quite a lot of Photoshop work and need my Monitor to give me an accurate picture whether my Wife is logged in or not and preferably without having to restart every time!
If anyone can throw any advice my way I would be most grateful.
Cheers Derek.

That's the same link I posted above.
Stick DMProxy in every users login items and you won't have to bother going into Terminal every time you log in after your kids
The problem is that *Login items* are ran only when you initially log in. If you simply switch users and then go back to your own user (which is alreaady logged in) the Login items are not ran.

ColorSync - Display Profile Affect Importing?

Hi,
I hope someone can answer this question for me. When you import photos into iPhoto, does your current Display Profile (in System Preferences) have any affect on the ColorSync profile added to your photos? For example, if you imported one batch of photos, then changed your Display Profile, would photos imported from then on have a different ColorSync profile put into them? Or does it not matter?
I really want to start importing photos into iPhoto, but I'm very concerned that my current Display Profile will get embedded into every single photo.

It only adds a profile to a file if that file does not already contain one. If the file has a profile assigned by the camera iPhoto does not override the existing profile.
However, if you edit a file and then drag it to the Desktop it will contain the profile that the monitor is set to. I just ran a test on two files that were stripped of their profile, imported into iPhoto, edited and then dragged to the desktop. I had previously set my monitor to the Adobe RGB profile and the end image files contained the Adobe profile.
Bottom line is: the original file imported must not have a profile assigned and be edited before iPhoto will assign one (to the modified file).
At least that's what's happening on my present setup. You can check it out if you have any files without a profile. I used i iView MediaPro to strip the profile from the files for my tests. You can download and use it in the demo mode to run tests yourself. User the Action->Manage Color Profiles menu option.
NOTE: On another test just now, with *iPhoto's option to embed a profile unchecked*, iPhoto still embeds a profile into the modified versions. Very strange.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Photoshop prefs, colorsync monior profiles and multiple users.

How can I make custom application preferences and color settings available to all users when my computer labs are set up on a domain environment and students log in as individual users. Right now Photoshop CS 3 prefs and monitor calibration profiles that were set at the admin level are not accessible to all users. When a user logs on to his or her account/environment none of the prefs (such as Photoshop color settings and prefs) show up in that user account. How can a make such custom settings the default for all users.
Thanks.

By default, Photoshop CS3 places any calibration files into the active user account. You just need to copy it to a location where everyone can see it.
Login to the user account that has the color settings and preference files you need. Then go to the ~/Library/Application Support/Adobe/Color/Settings/ folder. Copy the settings file to a location where all users can access it. Each user can then navigate to that location to load the settings file from within Photoshop.
If you want all users to have the exact same menu, keyboard and palette layouts, open Photoshop and set up everything to your preferences. Then choose Window > Workspace > Save Workspace. Give it a name and make sure all three check boxes are on. The file is saved in the ~/Library/Preferences/Adobe Photoshop CS3 Settings/WorkSpaces/ folder. This file cannot be accessed globally. It needs to copied into the same folder location of each user account. Once there, it can be loaded within Photoshop.

Color Management: Results differ between Lightroom and ColorSync

Hi. I'm on a Mac and using LightRoom 3 with a Canon PIXMA MG5250 printer.
I have read elsewhere on the web that choosing a profile from within Lightroom's Print interface is essentially the same as selecting "Color Sync" under "Color Matching" in the print dialog (as opposed to "Canon Color Matching") and then selecting the prifile there. The only difference is in what interface you use to pass the same instructions to the driver. And sure enough, when I select a profile in LR, the options under "Color Matching" are disabled (with the "Color Sync" radio button selected). The only thing is:
Selecting the profile in Lightroom produces a slightly brighter image.
I printed the same image on the same piece of paper side by side. First one image with CM from LR. Then I refed the sheet, moved the image over to the other side and printed again with CM set to ColorSync and profile selected in the print dialog. The latter produced noticably richer (and more desireable) blacks.
Should this be possible?

Back at work and my wide gamut monitors, and now I see the problem very clearly.
Lr Develop and Photoshop are basically in agreement, although there is the weird banding in the Photoshop version. The differences are all in the red channel, so here's once again how the full screenshot looks - the first as is, the second with a curves layer to make it clearer:
So let's forget the histogram for now (although the clipping still makes me suspicious) and figure out which version is the correct one. I tend to trust Photoshop, but there is one known bug that affects Prophoto files with Open GL "on" only. All other color spaces go clear of it. This could well be it, because it causes colored banding in shadow areas. The bug is acknowledged but still not resolved.
So try to turn off Open GL in Photoshop and see if the banding goes away.
If it does, and Lightroom Develop/Photoshop are in agreement, I'd probably leave it at that and settle for Jao's explanation above. As has been said before, the fact that there is a difference is in itself no mystery, since the previews are rendered into Adobe RGB and Develop uses linear Prophoto.
And then I'd recalibrate the monitor, making sure that it's properly warmed up, just to be safe.
I'll try to duplicate this when I get time, using images with similar deep blue tones. But my monitors are Flexscans, not Coloredges, and the Eizo profiling software is different, so it's not directly comparable.

ColorSync doesn't recognize scanner

The Devices panel in ColorSync Utility shows no scanners, even though I have a CanoScan 1220U connected that I use regularly via the PhotoShop import plugin.
I'm trying to get started with color management and this has stopped me before I have really begun because I'd really like to get this scanner onboard; the color has been most unsatisfactory.
I have installed the profile provided by Canon in the correct folder and, indeed, it shows up in ColorSync's Profiles panel. But if ColorSync doesn't know the scanner is there, what good is that?
Any ideas would be most appreciated.

ICC profile for getting books/posters printer?

Hey all,
Before I start using Aperture for getting books and posters printed, I had a question on ColorSync/ICC profiles. I'm by no means a pro, but know enough to get my color workflow in basic order.
A large poster I ordered through iPhoto came back with massive red shifting and huge loss of detail in the darker photos (it was a collage). Is there an ICC profile available that can be used so that when I soft proof with Aperture, it will give me better feedback on what photos printed via the printing service (Kodak) will look like? I really don't want to go through the hassle of getting more refunds...
TIA!

If you are using an apple cinema display that has been color calibrated I think you will get the desired result. If you are not using an apple display then you will go in circles like it did.
I'd like to qualify this statement. You should have a new professional display and use software calibration like Monaco or Pulse Color Elite from Xrite to bring your display to standardized state.
My older 22" Cinema display (which has been demoted to my business machine) will successfully calibrate thru Pulse Color Elite, but the monitor is dim and yellow compared to a successful calibration on my new 30" & 20" Apple displays or my 20" iMac G5.
As I'm laying out a sub-portfolio book to be printed via Apple, I'm assuming the only differences in color and gamut of the finished books are going to be due only to the differences in the RGB & CMYK worlds because I'm working on a calibrated workstation. I hope I'm right.

No embedded profile

Hi
I use dg foto art gold for designing albums. I notice that the exported files are flagged by photoshop that there is no profile attached. As I generally shoot and print as sRGB should I:
Assign sRGB profile.
Convert to sRCG profile.
On my system the unprofiled images look garishly bright in the red spectrum. Always hazy about this subject so your help is appreciated.
Cheers
john

Are you asking which of these two things you should do, or saying you want to do both?
If you want to Assign a profile, you need to assign the right one, the one the RGB numbers are in terms of, not just arbitrarily assign sRGB, unless the original photos were sRGB but didn't have it embedded.
Once you have assigned the correct profile, then you can convert to sRGB before you upload things somewhere, but if your albums are going to your own printer, then leaving them in the native profile might be better. If you are sending them out, then the print house might require another profile such as Adobe RGB or something particular to their printer and paper.
What is your RGB working space in Photoshop?
What role does Photoshop have with the albums and what do you do with the images once you've worked on them in Photoshop?

GIMP Printing and ColorSync... ?

Since discovering I can now print (to my Epson Stylus Color 1160) printer using the GIMP drivers furnished in Tiger 10.4.11, I nevertheless seem to be missing ColorSync support.
Images (photos and Photoshop images) don't seem to be printing with reliable color rendition. (All my artwork previously had been elaborately calibrated for screen display and printing via the Epson printing software and ColorSync. That is, until Epson decided to orphan the printer by abandoning software support for Tiger and beyond.)
When I search on the Internet for an explanation of the GIMP/ColorSync issue, I find numerous articles that assert that these GIMP drivers do not support my old ColorSync (ICC) profiles, and which articles are otherwise oblique, abstruse, and equivocal.
I can't understand what I'm supposed to do:
-- Turn off ColorSync (how?);
-- Re-calibrate new ICC profiles for the printer (again, how? By using the ColorSync Utility?);
-- Spend a fortune on ink and paper by trial and error test printing?
If you have a simple understandable explanation of how to print my existing ColorSynced image files in this situation, I'd surely like to know! And thanks!

I've downloaded GutenPrint 5.2.6, but haven't installed it because the docs (seem to) say that it won't reliably use the printer ICC profiles that I previously assigned via the Epson software...
The documentation has only a paragraph or two in the entire "manual" to address ColorSync.
The Gutenprint drivers are written to be used on many systems such as Linux, Mac OS X, and other *nix platforms. They were not written specifically for OS X and for use with ColorSync.
What the manual is saying is basically what I mentioned earlier. ICC profiles that were supplied by Epson for use with their own drivers paper, and ink will not produce the same output when used with a different driver such as Gutenprint. Likewise, the Epson provided ICC profiles will not produce the same results if you use third party ink or third party papers.
The Photoshop "color space" for my files is the "Adobe RGB (1998)." Not sure what will happen if I change this to sRGB for the image... (if that's possible).
I am far from expert in color managing. It may be of some benefit if you read a discussion on the Gutenprint forums at https://sourceforge.net/projects/gimp-print/forums/forum/4359/topic/3810875. Of course each printer is going to be different, but the principles outlined there would still apply. In that discussion, it was found that changing the color space to AppleRGB and then printing using "Same as Source" was getting close to the right output. You still may need to make some adjustments to the Density or Gamma controls in the Gutenprint settings.
One thing you will need to pay particular attention to is to make sure that you have the type of paper selected properly in the print window under Printer Features. Also, you will need to set the proper resolution and image type in the Gutenprint settings under Printer Features.
ColorSync profiles show up in the (Tiger) GIMP printing routine (one for each paper stock), but I'm not sure where these came from -- are they my original ICC profiles from my Epson software, or are they profiles GIMP furnishes?
The Gutenprint drivers do not provide any ICC profiles. The PPDs do contain directives to manage to the sRGB profile that comes with OS X as that is the color space that Gutenprint expects.
I was hoping there'd be a "simple" way to convert my old ColorSync profiles so that I could print them with reliable color rendition...
As I have 30 or 40 photos (of approx. 220MB) to be printed at 13" x 19", I'm a bit reluctant to go in and color balance them all in the ColorSync Utility (especially as I don't understand whether or not the ColorSync Utility is producing an ICC profile for the printer. (Or is the ColorSync Utility merely creating another screen profile?)
I have pretty much reached my knowledge limit on the use of ColorSync and the use of it with the Gutenprint drivers. As a practical matter, it is always best to experiment with smaller test prints and use copies of any images you test just to make sure you don't accidentally corrupt a good file.

ColorSync and Aperture Help!

I am trying to print from Aperture and get accurate results at least close to what I see on the screen. I have calibrated my monitor and have a profile set up. I have printer profiles in place, but no idea if they are active. I am very lost on this colorsync, color profile, management idea. I really just want my prints to look like what i see on the screen. Any kind of walk through or help would be GREAT.
Thanks

Assuming you have aperture set up as standard then the files are not viewable in finder. You need to read the manual to get an understanding of how aperture handles files, and how to set it up to meet your needs.
This part of the manual will tell you about managed vs. referenced files
http://documentation.apple.com/en/aperture/usermanual/index.html#chapter=3%26sec tion=1
And this part will tell you how to go about importing

Epson ICC profiles will not install in Mountain Lion

I have an Epson R1900 printer which requiress icc profiles. The generally agreed route has been to use those from Epson of America and these work fine on my PC. On the Mac however only the matte set will install. The glossy profiles bring up an error stating that I do not have enough permissions to complete the install. I believe this was also a known issue in Lion and I have found one suggested solution which was to adjust permissions in Colorsync and Profile folders in the Library.
However, in Mountain Lion this did not work for me. Does anyone else have success in installing these profiles?
Previous discussion here https://discussions.apple.com/thread/3319527?start=0&tstart=0

I just used the Pacifist tool to peer into the Oct 4, Epson Printer Drivers v2.12 for OS X package. In particular, for the R1900, both sets of the ICC profiles are installed into the following paths. Supporting code for this printer is installed under the InkjetPrinter2 hierarchy.
/Library/Printers/EPSON/InkjetPrinter2/ICCProfiles/SPR1900_A.profiles/Contents/R esources
/Library/Printers/EPSON/InkjetPrinter2/ICCProfiles/SPR1900_W.profiles/Contents/R esources
The AutoSetupTool is installed in:
/Library/Printers/EPSON/InkjetPrinter2/AutoSetupTool/EPIJAutoSetupTool2.app
Everything in the above paths is owned by root with group admin. The individual R1900 .icc files are read/write by root, read-only by everyone else. There are two categories of .icc files for the R1900 as shown below:
Stylus Pro R1900 A Profiles
Stylus Pro R1900 W Profiles

Using OneSight profiles in eLoad?

does anyone know if it is possible somehow to use the OneSight profiles in eLoad?
-if I export a OneSight profile it will show up as an .imp file...this dosnt seem to be uploadable in eload or????
-or can I some how convert it?
thanks
/felix

There are several places profiles can reside but best is to put in the Admin (All) main System Library:
~/Library/Printers/Your Printer/Profiles
Since they are OSX level additions have you looked to see if they are visible in:
Color Picker > Sliders > Rainbow Color Patch to the left
In ColorSync Utility:
Profiles > Other > /Library/Printers/Your Printer/Profiles…
I also have two separate Application Support Adobe libraries.
You can examine the Device profile by picking through the Printers list.
Or roll your own print workflow by duplicating and editting the Filters which can then be made to appear in the Printer dialogue by checking that as a Domain in the new filter.
Apple gives http://www.apple.com.colorsync support web address in Profile First Aid, which like much of ColorSync is out of date and dead.
You may have more joy reading through the ColorSync references in the Mac Developer Library:
https://developer.apple.com/library/mac/navigation/index.html
If you don't have a developer account already, sign up for the free one which lets you at least access all the libraries.
