Convert object colors, Ink Manager overview

Page 474 highlights

USING ACROBAT 9 PRO EXTENDED 468 Print production tools 9 Select a conversion option if applicable: Preserve Black Preserves the color values of objects drawn in CMYK, RGB, or grayscale during conversion. This option prevents text in RGB black from being converted to rich black when converted to CMYK. Promote Gray To CMYK Black Converts device gray to CMYK. Preserve CMYK Primaries When transforming colors to prepare CMYK documents for a different target print profile, preserves primaries. For colors with just one colorant, Acrobat uses that colorant. For colors with more than one colorant, Acrobat finds the color with the smallest color difference. 10 Click Document Colors to see a list of color spaces and spot colors in your document. 11 Click Ink Manager to specify the ink settings and create an ink alias. If an alias is set up in the Ink Manager, the alias name is next to the Ink Manager button in the Convert Colors dialog box. 12 Select a command from the list of Conversion Commands, and Move Up or Move Down to change the order of the conversion. 13 To create a preset based on your settings, click Save Commands. You can later import the settings by clicking Load Commands. Convert object colors If certain objects in the PDF don't match the color space of the document, you can use the TouchUp Object tool to correct them. The TouchUp Object tool can change the color space of selected objects. For example, if you place an RGB image in a CMYK document, use this tool to change only the RGB image and not affect the other PDF colors. You can change the color space temporarily or embed the profile with the object. Note: The TouchUp Object tool doesn't let you change the output intent, because that affects the entire document. 1 Choose Tools > Advanced Editing > TouchUp Object tool, and select the objects you want to convert. 2 Right-click the selection, and choose Properties. 3 Click the Color tab. 4 From the Convert To menu, choose the profile for specifying the color space of the object. The current color space of a single object (or identical color spaces for multiple objects) appears at the top of the Color tab for reference. Different color spaces for multiple objects aren't shown. 5 From the Rendering Intent menu, choose the translation method appropriate for the object. 6 (Optional) To embed the profile with the object, select Embed Profile. 7 Click Convert Colors. Ink Manager overview The Ink Manager provides control over inks at output time. Changes you make using the Ink Manager affect the output, not how the colors are defined in the document. Ink Manager options are especially useful for print service providers. For example, if a process job includes a spot color, a service provider can open the document and change the spot color to the equivalent CMYK process color. If a document contains two similar spot colors when only one is required, or if the same spot color has two different names, a service provider can map the two to a single alias. In a trapping workflow, the Ink Manager lets you set the ink density for controlling when trapping takes place, and it lets you set the correct number and sequence of inks. Last updated 9/30/2011

Select a conversion option if applicable:
Preserve Black
Preserves the color values of objects drawn in CMYK, RGB, or grayscale during conversion. This
option prevents text in RGB black from being converted to rich black when converted to CMYK.
Promote Gray To CMYK Black
Converts device gray to CMYK.
Preserve CMYK Primaries
When transforming colors to prepare CMYK documents for a different target print profile,
preserves primaries. For colors with just one colorant, Acrobat uses that colorant. For colors with more than one
colorant, Acrobat finds the color with the smallest color difference.
10
Click Document Colors to see a list of color spaces and spot colors in your document.
11
Click Ink Manager to specify the ink settings and create an ink alias. If an alias is set up in the Ink Manager, the alias
name is next to the Ink Manager button in the Convert Colors dialog box.
12
Select a command from the list of Conversion Commands, and Move Up or Move Down to change the order of the
conversion.
13
To create a preset based on your settings, click Save Commands. You can later import the settings by clicking Load
Commands.
Convert object colors
If certain objects in the PDF don’t match the color space of the document, you can use the TouchUp Object tool
to correct them. The TouchUp Object tool can change the color space of selected objects. For example, if you place an
RGB image in a CMYK document, use this tool to change only the RGB image and not affect the other PDF colors.
You can change the color space temporarily or embed the profile with the object.
Note:
The TouchUp Object tool doesn’t let you change the output intent, because that affects the entire document.
1
Choose Tools > Advanced Editing > TouchUp Object tool, and select the objects you want to convert.
2
Right-click the selection, and choose Properties.
3
Click the Color tab.
4
From the Convert To menu, choose the profile for specifying the color space of the object. The current color space
of a single object (or identical color spaces for multiple objects) appears at the top of the Color tab for reference.
Different color spaces for multiple objects aren’t shown.
5
From the Rendering Intent menu, choose the translation method appropriate for the object.
6
(Optional) To embed the profile with the object, select Embed Profile.
7
Click Convert Colors.
Ink Manager overview
The Ink Manager provides control over inks at output time. Changes you make using the Ink Manager affect the
output, not how the colors are defined in the document.
Ink Manager options are especially useful for print service providers. For example, if a process job includes a spot color,
a service provider can open the document and change the spot color to the equivalent CMYK process color. If a
document contains two similar spot colors when only one is required, or if the same spot color has two different names,
a service provider can map the two to a single alias.
In a trapping workflow, the Ink Manager lets you set the ink density for controlling when trapping takes place, and it
lets you set the correct number and sequence of inks.
