Embedded Profile mismatch -- is this my problem ?

    Normally the images I print with PS7 have sRGB profiles but today I
    tried to print an image which came with Adobe RGB 1998 profile.

    On opening it I got the mismatch message and I chose to convert it to
    my working space , sRGB.

    I then proceeded to follow my standard routine for printing (Use Epson
    870) BUT got a print with colors totally different to those on the
    screen and different to those of a print of the image which had been
    given to me .(reds became yellowish and orange became greenish).

    Anybody got any idea of what's gone wrong.

  2. I think you will have to explain what your standard routine is in some
    detail. i.e. what selections do you make in the Print with Preview panel and
    also in the Epson printer driver. In a properly colour managed system, your
    print should look reasonably close to your screen, regardless of the colour
    space you are using for the image in Photoshop.

    I thought I would just focus in my origanal post on the only thing
    which differed from my usual practice , namely opening a file which
    mismatched my working space(see original post) but here is my usual
    routine .I arrived at it more or less by trial and error as I have to
    admit not really understanding the division of labor as between PS7
    and the epson driver.

    1. open file . These are all sRGB (my digital camera seems to choose
    this) when I upload images so this was the first time I was confronted
    with the mismatch message so my guess is that this is where the
    problem is.

    2. Working space is set to sRGB in PS color settings ( never change
    these settings!)

    3.Once I do adjustments with PS (normally very little here and none
    relating to color management) I click on Print with Preview

    4. In the Color management section I click on Document ( which
    correctly shows source space as sRGB IEC6 1966 2-1).Print Space
    Profile I set as "Same as source" .Then Click Print\Properties and on
    the Main Tab select media type and Custom .On the drop down menu I
    select my preset config for the advanced features which, for the color
    management section , is selecting sRGB. The other 4 choices (ICM,No
    color adjustment ,etc are not touched -- the color controls are all
    at default setting of "0" for each of the sliders. ) As mentioned all
    thes settings have been saved so I leave them alone.

    This arrangement has worked so consistently that I rarely bother to
    print a test . But something is now wrong ! Incidentally the wildly
    wrong colors did not show in the Print with Preview selection -- the
    image looked just as I expected it should .

    I hope this is enough for you to solve my problem . Any help would be
    much appreciated. Obviously as I start getting more involved in
    digital photoraphy I am going to have to deal with files which are not
    sRGB and indeed may not have an embedded color space. So some progress
    here would be great.
    Thanks

  4. In the Print Space Profile you should select the appropriate printer profile
    for the paper you are using.

    In the Advanced features, select No Color Adjustment.

    Alternatively, you can choose ICM, in which case you should select "Printer
    Color Management" for the Print Space Profile.

    Printer profiles: if you don't have them installed on your system, use the
    1270 ones listed at the bottom of this page:

    Many thanks for this. I have tried to get 870 media specific profiles
    without success but in the process got some 1270 ones which I will
    try. I'll let you know what happens !

    I followed above using a 1270 paper profile. with no color adjustment
    .. This produced exactly same problem as before. I assume you meant me
    to convert the Adobe space to sRGB via mismatch menu.
    Sorry not to have better news . Any further thoughts.

    Meanwhile I shall try your other approach using ICM.
    Thanks

    Have now repeated exercise with ICM and "Printer Color Management"
    with same result ; blues , blacks,greens and whites look not too bad
    but reds/oranges come out yellow/greenish.
    Again I did the conversion to sRGB color space.

  8. No, I didn't mean you to convert the image colour space. It shouldn't make
    much difference. I assume you are using Epson photo papers and epson inks?

    The other slight possibility is the presence of out-of-gamut colours. Try
    View->Proof Setup->Custom and select your printer profile, Intent -
    perceptual and check Black point compensation. Then go to View->Gamut
    Warning. Any out-of-gamut colours in the image should switch to gray.

    The only other thing I can suggest is to print a standard colour test image
    such as the PhotoDisc target from http://www.inkjetart.com/custom/ . Note
    that this is an AdobeRGB (1998) image, so Assign AdobeRGB(1998) after
    opening the file, if necessary.
