Opaque
Use for heavy, nontransparent inks to prevent trapping of underlying colors but allow for trapping along
the ink’s edges. Use this option for metallic inks.
Opaque Ignore
Use for heavy, nontransparent inks to prevent trapping of underlying colors and to prevent trapping
along the ink’s edges. Use this option for those inks, such as metallics and varnishes, that have undesirable
interactions with other inks.
Adjust the trapping sequence
The trapping sequence (also called the trapping order) matches the order in which inks are printed at the press, but it
doesn’t match the order in which separations are produced at the output device.
The trapping sequence is particularly important when you’re printing with multiple opaque colors, such as metallic
inks. Opaque inks with lower sequence numbers are spread under opaque inks with higher sequence numbers. This
process prevents the last applied ink from being spread, and it still creates good traps.
Note: Don’t alter the default trapping sequence without first consulting with your prepress service provider.
1
Open the Ink Manager. The current trapping sequence is displayed in the Sequence column of the inks list.
2
Select an ink, type a new value for Trapping Sequence, and then press Tab. The sequence number of the selected ink
changes, and the other sequence numbers change accordingly.
3
Repeat the previous step for as many inks as necessary, and then click OK.

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.
Note: InDesign and Acrobat share the same Ink Manager technology. However, only InDesign has the Use Standard Lab
Values For Spots option.
