e Highlight menu in the Flaener Preview

panel provides several options for displaying

specic instances of transparency, including

Transparent Objects, All Aected Objects,

and Outlined Text. For example, the

Transparent Objects option highlights in red

all transparent objects.

Flaening transparency

When you print an InDesign le

that contains transparent objects,

InDesign performs a process called

attening, which converts all areas

of transparency into a collection of

opaque vector and raster objects that

retains the appearance of the original

objects. Flattening also occurs when

you export a  le with Adobe

Acrobat®  compatibility (such as a

/-a or /- le) or an 

le, using File > Export.

You can choose the attening quality

in the Transparency Flattener area

of the Advanced pane of the Print

dialog box or the Export Adobe 

dialog box. By default, the Preset

menu includes three options: Low

Resolution, Medium Resolution, and

High Resolution. In general, Medium

Resolution is appropriate for proof-

ing, and High Resolution should be

used for all nal output.

If you’re printing to a device that

does not support Adobe PostScript®,

or creating a  le that you will

send to a client as a proof, you should

check Simulate Overprint in the Out-

put pane of the Print dialog box. is

way, the proof will look the same

as it looks onscreen with Overprint

Preview (View > Overprint Preview)

enabled. is is especially important

when using spot colors.

If none of the default presets meets

the requirements of your printer—or

your output provider’s printer—you

can create custom attener presets by

choosing Edit > Transparency Flat-

tener Presets and then clicking New

in the Transparency Flattener Presets

dialog box. For information about

creating attener presets, refer to

InDesign Help.

Note that attening is not neces-

sary when creating a /- le

and printing to an Adobe  Print

Engine .

Managing transparency

In a document that will be attened,

it is a good practice to place text on a

higher layer than transparent objects.

is removes the chance that some

text characters will become outlined

in the attening process.

e Flattener Preview panel (Win-

dow > Output > Flattener Preview)

helps designers and printers prevent

mistakes and helps ensure high-

quality printed results by identifying

transparent objects or objects that

interact with transparent objects.
