Color Libraries
Color Libraries
Lists the color libraries that are defined in the color database. Two kinds of libraries are available—factory and user. You cannot change factory libraries, but you can create and edit user libraries. Select a color library to display the colors contained within, or in the case of user libraries, to add or remove colors.
Add
Opens the New User Library dialog box, enabling you to add a new user library for a specific color space, such as CMYK or L*a*b*. For example, Matchprint Inkjet proofers that support white ink, such as the Epson Stylus Pro WT7900 printer, can use CMYKW color libraries in hot folders or virtual printers.
Remove
Removes the selected user library from the color library database
Export
Enables you to export a user library, so you can import it into another Color Database Editor
Import
Enables you to import a user library into the Color Database Editor
Colors
Colors
Enables you to add new colors to your color library
Search
Enables you to search for a color in the currently selected library
Add
Adds a new user-defined color to a user library
Remove
Removes a selected color from a user library database. Select a user-defined color, and click Remove.
Alternate Color
Alternate Color
Displays the alternative color space and values for the color—L*a*b*, CMYKW, or CMYK. You can edit the alternate color space in user libraries only.
Note: The CMYKW color space is for Matchprint Inkjet proofers that support white ink, such as the Epson Stylus Pro WT7900.
LAB
Specifies that your new color library use the L*a*b* alternative color space for color definitions. In the Color Database Editor, the Alternate Color box enables you to apply a L*a*b* color recipe for each new color that you add to the library.
Opacity
Specifies the opacity of an L*a*b* color. Only Epson Stylus Pro WT7900 printers with white ink can use the Opacity option to print white ink. White ink is the only opaque ink available with the Epson Stylus Pro WT7900 printer. Settings of 1 or greater enable white ink to print. (The Opacity value is not an ink value. Kodak Proofing Software uses information in the proofer profile with the L*a*b* color definition to transform the Opacity value to an ink value for white ink.) Typically you will use the Opacity option to define white flood, but you can also use it with the LAB options to define opaque colors. If desired, you can print the White Level and Opacity Chart to identify an opacity value for white ink.
Note: The Opacity setting does not affect the preview color patch.
CMYK
Specifies that your new color library use the CMYK alternative color space for color definitions. In the Color Database Editor, the Alternate Color box enables you to apply a CMYK color recipe for each new color that you add to the library.
CMYKW
Specifies that your new color library use the CMYKW (cyan, magenta, yellow, black, and white) alternative color space for color definitions. In the Color Database Editor, in the Alternate Color box, you can apply a CMYKW color recipe for each new color that you add to the library. The White option specifies how much white ink to use on the Epson Stylus Pro WT7900 printer. You can use the White option to define a recipe for objects in input files that include white ink—that is, specify a combination of values for Cyan, Magenta, Yellow, Black, and White. Alternately you can use the White option to define a recipe for objects in input files that define white flood—that is, specify a value for only White. If desired, you can print the White Level and Opacity chart to help identify the needed value for the White option.
Only Epson Stylus Pro WT7900 printers with white ink can use the White option to print white ink.
Trapping information
Use default values
Applies the default color trapping values that are defined in the input file
Trap Style
Specifies the opacity for the color. Select one of the following options:
- Normal—treats the color as translucent. Normal colors, or objects covered by or placed on top of Normal colors, may be trapped.
- Transparent—ensures that the color is not trapped
- Opaque—ensures that the color is not spread and that objects covered by the color are not spread. Other colors may trap to Opaque colors, and objects covered by Opaque colors may be choked back.
- Opaque Ignored—ensures that the color is not spread. Other colors do not trap to Opaque Ignored colors.
- Dieline—ensures that the color is not trapped. For composite proofs, the color knocks out. When outputting separations, the system treats the color as an overprint ink.
- Varnish—ensures that the color is not trapped
- Emboss—ensures that the color is not trapped
Neutral Density
Specifies the neutral density for the color. The neutral density values are determined automatically by the trapper, based on the color recipe values and from the process color recipe.
It is recommended that you clear this box. If you need to specify a special neutral density for trapping purposes (for example, you want to override the trap values so a lighter color overrides a darker color), enter a high value. The maximum value is 4.
To apply the same density and characteristics as black, it is recommended that you select the Treat Color as Black check box instead of changing the neutral density setting.
Treat color as black
Treats the color as black, applying the same density and characteristics as black. Therefore, you can trap all surrounding colors into that color, or create a stay-away trap for any underlying colors.
Revert
Cancels the color recipe changes to the selected color and reverts to the original color recipe
Apply
Saves the changes to the color recipe for the selected color
