Downsample (Off) Reduces image resolutions that exceed the For Images Above value to the resolution of the output

device by combining pixels in a sample area of the image to make one larger pixel.

Average Downsampling To Averages the pixels in a sample area and replaces the entire area with the average pixel

color at the specified resolution.

Subsampling To Replaces an entire area with a pixel selected from that sample area, at the specified resolution. Causes

faster conversion time than downsampling, but resulting images are less smooth and continuous.

Bicubic Downsampling To Uses a weighted average, instead of a simple average (as in downsampling) to determine

pixel color. This method is slowest but produces the smoothest tonal gradations.

Compression/Image Quality Applies compression to color, grayscale, and monochrome images. For color and

grayscale images, also sets the image quality.

Anti-Alias To Gray Smooths jagged edges in monochrome images. Choose 2 bit, 4 bit, or 8 bit to specify 4, 16, or 256

levels of gray. (Anti-aliasing may cause small type or thin lines to look blurry.)

Note: Compression of text and line art is always on. To turn it off, set the appropriate Distiller parameter. For details, see

the SDK information on the Acrobat Developer Center at

www.adobe.com/go/learn_acr_devcenter_en (PDF, English

only).

Policy Opens the Image Policy dialog box, where you can set processing options for Color, Grayscale, and

Monochrome images that are less than the resolutions you specify. For each type of image, enter a resolution value,

and then choose Ignore, Warn And Continue, or Cancel Job.

Fonts panel options

The Fonts options specify which fonts to embed in a PDF, and whether to embed a subset of characters used in the

PDF. You can embed OpenType®, TrueType, and PostScript fonts. Fonts that have license restrictions are listed with

a lock icon

. If you select a font that has a license restriction, the nature of the restriction is described in the Adobe

PDF Options dialog box.

Note: When you combine PDF files that have the same font subset, Acrobat attempts to combine the font subsets.

Embed All Fonts Embeds all fonts used in the file. Font embedding is required for PDF/X compliance.

Embed OpenType Fonts Embeds all OpenType fonts used in the file, and maintains OpenType font information for

advanced line layout. This option is available only if either Acrobat 7.0 (PDF 1.6) or Acrobat 8 (PDF 1.7) is selected

from the Compatibility menu in the General panel.

Subset Embedded Fonts When Percent Of Characters Used Is Less Than Specifies a threshold percentage if you want to

embed only a subset of the fonts. For example, if the threshold is 35, and fewer than 35% of the characters are used,

Distiller embeds only those characters.

When Embedding Fails Specifies how Distiller responds if it cannot find a font to embed when processing a file.

Always Embed To embed only certain fonts, move them into the Always Embed list. Make sure that Embed All Fonts

is not selected.
