Getting printed scans to match the original

    I have an Epson 830U photo printer. I scanned a picture in from my Epson
    1240U flatbed and printed it (from paintshop pro 6) but the printed picture
    had too much red hue and probably too much colour saturation (the original
    on screen looked fine). Is there a way I can ensure the printed result
    matches the original without having to use the 'trial and error' method and
    wasting a load of photo paper?

    Google: gamma adjustment

    You need to adjust your monitor.

    Not sure if it's the same in PSP6 but in PSP10 Monitor Calibration is under
    the File menu.

    Maybe the problem is the monitor. Get a copy of a good color
    calibration file, and display it on the monitor. Make sure that the
    display card has no options that are modifying its output to the
    monitor. Everything in the display properties software has to be set to
    default to start with.

    Check the monitor to see that it is tracking the grey scale properly,
    so that you know it is in true black and white to start with. If you
    see any colourations or tinting in the scaling, this is most likey part
    of the problem. The black level chip must be just visible, and the
    white level chip must be visible without any clipping or bleeding.
    There should be very little or no variation of colour in the chips in
    between.

    More often than not, differences are the errors in the monitor, and
    with the display card to start with. After correcting the dispay
    problems, then you can go on to investigating any problems with the
    printer and scanner.

    This article is worth a read.
    http://www.ddisoftware.com/qimage/icc.htm
    Monitors can be set up with different color profiles. sRGB seems to be a
    good starting point.
    PSPro 9 let`s you adjust a few parameters. I`m not sure about earlier
    versions tho`.
    It`s abit of trial and error, until you master it.

    I would say definately the problem lies with the printer - photo looks fine
    on the monitor - same as scanned. I do refill my own cartridges and I know
    that can alter tones a bit. What I was thinking is could i scan a colour
    chart, print it and then re-scan and use some software to 'calibrate' the
    source file to correct the printer output. The colour monitor is a new LCD
    type and looks not to have any emphasis on colours as all photos look 'good'
    on it.

    why? Guest

    It's gamma setting / matching the color for each device. This topic was
    raised a while ago but the last thread I remember should still be found
    by searching

    http://groups.google.com/group/24hoursupport.helpdesk?

    There were several links about the topic.

    Threads, searching with author:why? gamma
    http://groups.google.com/group/24ho...why?+gamma&qt_g=1&searchnow=Search+this+group
    or shorter
    http://makeashorterlink.com/?F3942134C

    Another search - print color monitor gamma , still in 24HSHD, while
    searching al all groups has 29,000 hits. Many of those are groups
    dealing with - photo apps, photos digital, graphics apps.

    Reading of the existing info like ,

    What you are talking about is called color management.
    You need to install color management tools to do this.
    It involves correcting the monitor (the monitor is always always off,
    no matter what you think of how it looks) and using files that fix the
    known behavior of the scanner and printer.

    Note that all three are critical parts in this; you're just guessing if
    you don't try to fix all three at once.

    Yes, it will affect the results that you aren't using known inks, but
    there is nothing you can do about that yet. Certainly not before you
    have fixed the other differences.

  10. In Mitch spewed forth:
    Another good reason to use OEM ink cartridges, IMO.
