    							2.Open the image. Accept the embedded color profile if there is one:
    Otherwise accept the default that Adobe Photoshop proposes:
    3.Once you have defined the color space in which you are going to work, you can if you like make a
    soft proof, which means emulating on the screen how the image will look when printed. To do this,
    you will need an ICC profile for your monitor. Select View > Proof Setup > Custom. Use the
    following information to select options in the Proof Setup window.
    ●Profile: choose the profile based on the printer model and paper type you intend to use.
    ●Preserve Color Numbers: this checkbox tells the application how to simulate the documents
    appearance without converting colors from the Document Space to the Proof Profile Space.
    It simulates the color shifts that may occur when the documents color values are interpreted
    using the Proof Profile instead of the Document Profile. This option is not recommended.
    ●Intent: this menu allows you to choose a rendering intent for the conversion from document
    space to simulation space, letting you preview the effects of different renderings. See 
    Set the
    rendering intent on page 69.
    ●Use Black Point Compensation: this option is recommended if you have chosen the Relative
    Colorimetric rendering intent. See 
    Perform black point compensation on page 68.
    ●Paper White: this checkbox emulates the whiteness of the paper on the monitor. The effect
    is the same as using the Absolute Colorimetric rendering intent.
    ●Ink Black: this checkbox turns off the black point compensation for the rendering from
    simulation to the monitor. So, if the simulation space black is lighter than the monitor black,
    you will see the washed-out blacks on the monitor. This option is not recommended.
    ●Preview: if this checkbox is enabled (recommended), the changes you make in this window
    are reflected in the image immediately.

    							4.When you are ready to print the image, open the Print with Preview window from the File menu. In
    the Color Management tab you can select:
    ●Source Space: Document (automatically assigned for you).
    ●Profile: select the profile you will use. We recommend using Adobe RGB. If neither Adobe
    RGB or sRGB is selected, then choose the appropriate ICC profile for the paper loaded, and
    remember to select later on in the driver the option Managed by Application.
    ●Intent: See 
    Set the rendering intent on page 69.
    Driver settings
    In the Paper/Quality tab (Windows) or Image Quality panel (Mac OS), set Print Quality to Best.

    							In the Color tab (Windows) or Color Options panel (Mac OS), you have the following Color Management
    options. Select the same option that you selected in the Print dialog box above (Print Space section,
    Profile option).
    ●sRGB: this is the default color space. The input RGB data are converted to CMYK using the printers
    internal color maps, which depend on the paper type and print quality selected. These are the most
    “versatile” color maps, producing saturated colors for CAD and office applications and also
    producing good results with photographic images.
    ●AdobeRGB: similar to sRGB, but using the AdobeRGB to CMYK internal color maps, which are
    designed for AdobeRGB input data with a bigger source gamut. Best suited to digital photography.
    ●Managed by Application: the driver will not perform any color correction. This path can be used
    when building custom RGB printer profiles and applying them within the application (the application
    is responsible for applying the right color management by using the custom RGB printer profiles).
    In this case, make sure that you have selected the right media profile in the Print Space, Profile
    option in the application print command (see above).

    This topic outlines one way to have good control over the printed colors you will obtain from your printer;
    there are many other ways. Before starting, ensure that your paper type has already been calibrated.
    Application settings
    1.Open Adobe Photoshop and select Color Settings from the Edit menu (Windows) or from the
    Photoshop menu (Mac OS).
    ●Working spaces: the working space is the color space you want to use when manipulating
    the image. We recommend using the color space that comes with the image (see Color
    Management Policies below), if any; otherwise, our recommended default settings are: RGB:
    Adobe RGB 1998, CMYK: SWOP for the USA and Euroscale Coated v2 for the rest of the
    world.
    ●Color Management Policies: select Preserve Embedded Profiles.

    you have been working while editing the image.
    ●Profile: select PostScript Color Management (if you do not see this option, select Printer Color
    Management). With this option, the application tells the driver which source profile and
    rendering intent should be used for the conversion to the print space. In this case the driver
    will use the Document profile and the rendering intent selected below. The drivers Input
    Profile and Rendering Intent settings are overridden.

    The applications PostScript Color Management option will override the color settings of the driver (Input
    Profile and Rendering Intent). In this case, the driver will use the applications Document profile and
    selected rendering intent. Then, we have only to select in the driver:
    ●In the Paper/Quality tab (Windows) or Image Quality panel (Mac OS), set Print Quality to Best.
    ●In the Color tab (Windows) or Color Options panel (Mac OS), check the Automatic PANTONE
    Calibration or HP Professional PANTONE Emulation box.

    Get accurate colors from Adobe InDesign CS
    This topic outlines one way to have good control over the printed colors you will obtain from your printer;
    there are many other ways. We describe the hard-proofing technique that shows you on your printer
    how your colors will appear when reproduced in a press. Before starting, ensure that your paper type
    has already been calibrated.
    NOTE:EPS, PDF and grayscale images dont allow page-layout applications to manage their colors.
    In addition, such images are displayed very poorly on a monitor.

    							Application settings
    1.Open Adobe InDesign and select Color Settings from the Edit menu.
    ●Working spaces: the working space is the color space you want to use when manipulating
    the image. We recommend using the color space that comes with the image (see Color
    Management Policies below), if any; otherwise, our recommended default settings are: RGB:
    Adobe RGB 1998, CMYK: SWOP for the USA and Euroscale Coated v2 for the rest of the
    world.
    ●Color Management Policies: select Preserve Embedded Profiles.
    ●Rendering Intent: see 
    Set the rendering intent on page 69.
    ●Black Point Compensation: this option is recommended if you have chosen the Relative
    Colorimetric rendering intent. See 
    Perform black point compensation on page 68.
    2.Create or open the image with its own or the most appropriate color space. Then retouch the image
    as needed.
    3.When you have the image ready to send to the output device, that is the moment to simulate on
    your printer what will appear on the output device. You must convert the image from the source or
    work profile to the output CMYK device, and then again from the output CMYK device to the printer
    profile (calibrated).
    In InDesign we recommend the Proof Setup command (View > Proof Setup -> Custom). This
    command lets you select the proof profile in the source space when printing. You can also see a
    simulation on your monitor. We recommend as follows:

    							Each object in InDesign has its own color management. The InDesign elements (native) use the
    working spaces (default profiles) and the rendering intent defined in Color Settings, and the placed
    objects have their own assigned profile and rendering intent. Then, each element is converted from
    its own color space to the simulation color space, using its own rendering intent.
    ●Profile: select the profile that corresponds to the device you want to emulate (usually a
    particular press profile or an standard press profile)
    ●Paper White: this checkbox emulates the whiteness of the paper on the monitor. The effect
    is the same as using the Absolute Colorimetric rendering intent.
    ●Ink Black: this checkbox turns off the black point compensation for the rendering from
    simulation to the monitor. So, if the simulation space black is lighter than the monitor black,
    you will see the washed-out blacks on the monitor. This option is not recommended.
    4.Select File > Print to print the image, converting it to an output space that depends on the printer,
    the paper type and the print quality.
    ●Select the Output tab (on the left), and then select Composite CMYK, in order to see the
    CMYK profiles.
    ●Select the Color Management tab to see the following options.
    ●Source Space: select Proof to emulate the proof color space.
    ●Profile: choose the profile based on the printer model and paper type you intend to use.
    ●Intent: select Relative or Absolute Colorimetric. The only difference is that Absolute
    Colorimetric emulates the background color of the paper to be used by the press, while
    Relative Colorimetric maps the paper color of the press to the paper color of the printer.

    							Driver settings
    The PostScript driver is recommended for page-layout applications because it can color–manage CMYK
    data, RGB data or both simultaneously.
    In the Paper/Quality tab (Windows) or Image Quality panel (Mac OS), set Print Quality to Best.
    In the Color tab (Windows) or Color Options panel (Mac OS), select Application Managed Colors and
    check the Automatic PANTONE Calibration box. When the application performs color conversion to the
    printers color space, the printer should accept these colors without changing them. Make sure you have
    selected the right media profile in “Print Space, Profile” above.
    Printer settings
    Ensure that the Paper Type setting on the front panel corresponds to the paper you intend to use.

    This topic outlines one way to have good control over the printed colors you will obtain from your printer;
    there are many other ways. We describe the hard-proofing technique that shows you on your printer
    how your colors will appear when reproduced in a press. Before starting, ensure that your paper type
    has already been calibrated.
    NOTE:EPS, PDF and grayscale images dont allow page-layout applications to manage their colors.
    In addition, such images are displayed very poorly on a monitor.
    Application settings
    1.Open QuarkXPress and select Preferences from the Edit menu (Windows) or the QuarkXPress
    menu (Mac OS). Then select Quark CMS from the Preferences dialog box.
    2.Ensure that the Color Management Active box is checked.

    							3.The Destination Profiles area lets you choose profiles that correspond to your devices: Monitor
    profile, Composite Output profile and Separation Output profile. Select in the Separation Output
    profile the profile of your output device (press) which you want to emulate on your printer later.
    Select in the Composite Output profile your printer profile; remember that it depends on the printer
    model, paper type and print quality option.
    4.In the Default Source Profiles you must set the default profiles for solid colors and images that dont
    have embedded profiles. The following default profiles are recommended: RGB: Adobe RGB 1998,
    CMYK: SWOP for the USA and Euroscale Coated v2 for the rest of the world. Also select the
    rendering intent, which QuarkXPress uses for all conversions; if in doubt, select Relative
    Colorimetric. See 
    Set the rendering intent on page 69.
    5.Check the box Color Manage RGB sources to RGB destinations in the RGB Default Source
    Profiles and Color Manage CMYK sources to CMYK destinations in the CMYK Default Source
    Profiles.
    6.The Display Simulation tells QuarkXPress how the display simulation should behave:
    ●None means that it doesnt simulate anything on the display.
    ●Monitor Color Space means that it converts from the source profile to the display profile for
    display only.
    ●Composite Output Color Space makes the display simulate a composite printer: that is, a
    printer without separate plates for different colors, such as an inkjet printer.
    ●Separation Output Color Space makes the display simulate a separations printer: that is, a
    printer with separate plates for different colors, such as a digital press.
    You can select Monitor Color Space if you want to display only, or you can select the Separation
    Output Color Space if you also want to see the simulation of the output device on the monitor.
    You can simulate the final output with the printer (hard–proofing) and with the monitor (soft-
    proofing ).
    7.Open and retouch the document as you like.
    8.Select File > Print > Setup > Printer Description, and select your printer.
    9.Select File > Print > Profiles.
    ●Select the appropriate Separation Output Profile (emulation) and Composite Output Profile
    (printer).
    ●Check the Composite Simulates Separation box, then Quark will perform the simulation.
