Totally confused by color management

    I'm running Win XP, and Photoshop 7. I have a Sony CRT and
    I have the profile for the Sony Monitor. I have a Canon
    digital camera.

    I just purchased an HP Photosmart 8250 (vivara inks - seven
    ink cartridges, etc). I am using the paper recommended for
    the printer.

    I am totally confused as to how to organize the different
    color settings in PS.

    The photos produced by the Canon have the standard embedded
    srgb ie66 etc. profile.
    My working space is Monitor - RGB Sony Triniton etc.

    So first I am asked if I wish to use the embedded profile or
    the working space. So I choose the working space because
    that is the monitor image from which I'll be adjusting the
    photo - is this correct?

    My plan is to make a print on my HP 8250.

    So I go to image/mode/assign profile. Here I am given a
    choice of:
    don't color manage
    working RGB - Sony Trinitron etc.
    or.....a large dropdown list of many different printers,
    srgb settings etc. Should I choose the profile for my
    HP 8250 with the paper I'll be using?

    If I choose the profile for the HP printer, the picture on
    the screen looks much less color accurate than it does if I
    choose the RGB Sony Triniton. So this is very confusing to
    me. Which should I choose and more importantly, why?

    Then I adjust the levels, colors, brightness, etc. of the
    image on the screen and I'm ready to print.

    I have a new set of options :)

    The printer allows me to choose either
    Adobe RGB
    Managed by application

    Once again, which do I choose? Since I've told PS to use
    the printer and paper, should I choose managed by application?

    My monitor also has a setting for sRGB. When I used this
    setting, all my prints had a very mild blue tint.

    It seems that when I use Adobe RGB, the colors are vibrant
    but everything is a drop too red and this also sometimes
    happens with Colorsmart/sRGB.

    Thanks to all who read this long post and as I'm sure is
    obvious by now, I don't really understand the "art" of color
    management. I've tried several times to study the help
    menus in PS, but I can't really understand much more when
    I'm done.

    All help, clarifications, links to clarifications, greatly

    Sorry, I don't know anything about your printer, or how it handles Colour

    For a workflow which is well proved for Epson printers, have a look at go to "Notices & Info" then to "How to Print for
    Accurate Colour".

    You should be able to adapt this routine, all you need to do is ensure your
    HP Printer does NOT do any Colour Management, and that Ps is using the
    correct profile for your printer and paper.

    Your problem is that you don't understand color management especially
    profiles and got confused. Profiles categorized into input (camera, scanner
    etc.), output (monitor, printer etc.) and abstract (working space). So
    choose the appropriate one to work with. If you shoot with a sRGB profile
    embedded, choose sRGB working space in Photoshop color setting (then no
    question will be asked because the color profile is the same) and always
    choose working with embedded profile if your working space is different.
    Don't assign profile or convert profile unless you know what you are doing.
    But first of all you need to calibrate your monitor conforming to standard
    visual for consistent color. This can be done visually by Adobe Gamma
    (software) or the more precise colorimeter like GretagMacbeth EyeOne Display
    (hardware). For printing, you can choose to let Photoshop do the color
    management or the printer to do color management but not both. It is quite
    tricky here depending on printer software and Photoshop print setting to off
    either one of the printing color management. If you do it right, the print
    could match the display screen very close.

    Hi there Louise. Well, first, it's not all that difficult. I
    have an HP 7550 printer, so I know the software that comes with HP
    The first thing you need to do is to calibrate your monitor. You
    can do a rough calibration using Adobe's color calibration feature
    that's built into PhotoShop, but you're better off getting a
    calibration package like Pantone or Monaco. These packages come with
    software and a colorimeter. A colorimeter is a sensor that attaches
    to your monitor, and takes an accurate measurement of the colors as
    the calibration software is running. They are easy to use and only
    take a few minutes.
    Once you have your monitor calibrated, you need to calibrate your
    printer. They do make packages to do that, but they are expensive, so
    you're better off using one of the online companies that do this.
    I've used Cathy's Profiles numerous times with good success, and she
    only charges $40 per profile. ( )
    The first thing that you need to do when printing is to turn off
    all of the automatic settings in the printer's software. To do this,
    when you go to print, you have a window that pops up that says Print,
    and has a button that says "Properties". Click on Properties and you
    will see another window that has numerous tabs at the top (Quality,
    Layout, Features, etc.). Click on the "Quality" tab and you will see
    a button that says, "HP Digital Photography" on it. You will
    see numerous "auto" features like Contrast Enhancement, Digital Flash,
    etc. Make sure all of these boxes are unchecked, and the Smart Focus
    is turned off. Every time you try to print at "Best" quality, these
    boxes will always be checked, so you need to uncheck them each time
    you open PhotoShop.
    When you calibrate your printer, you will need a profile for each
    type of paper that you are going to use, so you might want to get a
    profile for the paper you use the most first, just to see if you're
    satisfied with the profile.
