Applying Flattener Settings

Keep in mind that applying flattener settings is the same as flattening

transparencya permanent change that cannot be undone.

Alternatively, you can flatten transparency in a copy of the document

without affecting the original PDF fileusing PDF Optimizer; see the

next section “Flattening Transparency Using PDF Optimizer.”

To apply the flattener settings to the PDF document:

1. In the Flaener Preview dialog box, specify aener seings.

2. In the Apply To PDF area of the dialog box, select the page or

pages to apply the aener seings to.

3. Click Apply. You cannot undo this operation.

Flattening Transparency Using PDF Optimizer

To create a copy of the PDF file with flattened transparency, use the

Transparency panel in PDF Optimizer. PDF Optimizer applies

transparency settings to all pages in the document before applying any

other optimization settings you have selected. To flatten transparency

using PDF Optimizer:

1. Choose File > Save As > Optimized PDF.

2. Select the Transparency option in the le column. If the document

has aener seings associated with it, Acrobat uses these seings

as the initial values in the Transparency panel. Otherwise, it uses

the seings last used in the panel.

3. Choose a aener seing.

4. Click OK to permanently aen transparency in the le. You are

asked to provide a name and location for the new le.

Note: When you click OK in the PDF Optimizer dialog box, PDF Optimizer applies all

the selected seings in all panels, whether you have recently applied them or not. To

prevent accidental changes, review the seings in the PDF Optimizer panels before

clicking OK. For more information on PDF Optimizer seings, see “Using PDF Optimizer

to optimize les for print” in this chapter.

Reducing File Size

You may be able to reduce the file size of a PDF file simply by using the

Save As command. This command rewrites the file, removes duplicated

or unnecessary information, and does not require you to regenerate the

PDF file from the source file.

If you wish to further reduce the file size, choose File > Save As >

Reduced Size PDF. This also gives you the option to change the version

compatibility of the PDF, and uses a preset optimization setting. Select

the version compatibility that you need (or select the default option to

Retain Existing format), and click OK. Note that reducing the version

may change the content of the file. For example, converting a file from

PDF 1.4 (Acrobat 5.0) to PDF 1.3 (Acrobat 4.0) compatibility requires

transparency to be flattened; this can sometimes result in increased file

sizes if image compression and resolution are retained.

Using PDF Optimizer

Acrobat PDF Optimizer allows you to unembed fonts, resample and

re-compress image content, change the version compatibility, remove

components you no longer need in the file, and flatten transparency.

The options you choose in PDF Optimizer depend on your workflow.

For high-resolution printing, use caution when downsampling or

compressing images, unembedding fonts, or flattening transparency.

More aggressive downsampling and compression are only appropriate

for a file that is intended for on screen viewing.

Note: Optimizing a digitally signed document invalidates the signature. Optimizing a

PDF/X le can invalidate the le if the resulting document’s fonts are not embedded.

To optimize a PDF file:

1. Choose File > Save As > Optimized PDF.

2. Click Audit Space Usage to view a report of the total number of

bytes used for specic document elements. e results appear in

actual bytes and as a percentage of the total le size. Auditing the

document can help you decide which options to select.
