with a pixel of the average shade. Select Subsample to use a pixel in the center of the sample area and
replace the entire area with that pixel value. This method is significantly faster, but results in images that are
less smooth. Select Bicubic to use a weighted average to determine pixel shades. This method is the slowest
but most precise and results in the smoothest tonal gradations.
Grayscale resolution: Select the resolution to use for grayscale images. Note that this setting has an impact
on the grayscale downsampling process.

Color compression: Select the compression to use for the color images. Flate is a lossless compression
method, so no data is lost in the process. It works well on images with large areas of single shades or
repeating patterns, such as screen shots and simple images created with paint or drawing programs. JPEG
removes image data and may reduce image quality, but may be suitable for continuous-tone photographs
containing more detail than can be reproduced onscreen or in print. Since JPEG eliminates data, it can achieve
much smaller file sizes than Flate compression. Select Auto to let the application choose the best compression
method automatically.
Grayscale downsample: Select the downsampling option. Downsampling reduces image size by breaking
images down into small areas in which multiple pixels are replaced by single pixels. The Color resolution you
enter in the following box is used to control the downsampling process. Select None to prevent grayscale
downsampling. Select Average to average pixel color in each sample area and to replace the entire area with a
pixel of the average color. Select Subsample to use a pixel in the center of the sample area and replace the
entire area with that pixel value. This method is significantly faster, but results in images that are less
smooth. Select Bicubic to use a weighted average to determine pixel shades. This method is the slowest but
most precise and results in the smoothest tonal gradations.
Color resolution: Select the resolution to use for color images. Note that this setting has an impact on the
color downsampling process.

Permissions password: Enter a password in this box only if you want users to be able to change the
security options of the generated PDF files.
User password: Enter a password in this box only if you want to prevent any user who does not have the
password you enter in this box from opening the generated PDF files.
Allow printing: Select to let users print the generated PDF files.
No changes: Select to prevent users from changing the content of the document.
No copying: Select to prevent users from copying content from the PDF file. This also blocks applications that
need direct access to the content of the PDF.
Allowannotations: Select to let users add or change annotations in the PDF file. Annotations include links,
bookmarks, attachments and comments.
Font group
Embed all: Select to embed the entire font of all fonts used in the variable content document within the
generated PDFs. Using this option may result in large PDFs, especially if many fonts are used. Note that those
fonts installed by default with the Adobe Acrobat and Adobe Reader are never embedded.
Subset: Select to embed only a subset of the Type 1 and TrueType fonts used in the document. A font subset
is in fact composed of only those characters that are actually used in the document. This option can only be
used if the Embed all option is selected. Note that if more than 35% of the characters included in a font are
used in the document, the entire font is embedded. This option often produces smaller PDF files and ensures
proper PDF display.
