l Color images group
l 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. Note that configurations that were created with an earlier version of PlanetPress Suite Workflow
Tools and that included tasks set not to use any compression will by default be set to use the Flate compression
method.
l Color downsampling: 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 down-
sampling. 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.
l Color resolution: Select the resolution to use for color images. Note that this setting has an impact on the
color downsampling process.
l Security group
l Permissions password: Enter a password in this box only if you want to prevent users who does not have
this password from changing the security options of the generated PDF files.
l PDF open password: Enter a password in this box only if you want to prevent users who does not have this
password from opening the generated PDF files.
l Allow printing: Select to let users print the generated PDF files.
l Allow changing the document: Select to let users edit the generated PDF files.
l Allow content copying: Select to let users copy content from the generated PDF files.
l Allowform filling: Select to let users enter information in the form fields included in the generated PDF files.
l Font group
l Embed all: Select to embed the entire font of all fonts used in the variable content document within the gen-
erated 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. If a font is not embedded in
your PDF, opening it on another computer or printing it may cause it to be substituted by another default font.
l 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 fonts 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.
l Initial view group
l Zoom factor: Select the magnification at which you want Adobe Acrobat or Adobe Reader (or other PDF
viewer) to open the generated PDF. Choose the Fit in window option to display the entire page using the avail-
able screen space, or choose a percentage of the actual document size.
l Show: Select the information you want Adobe Acrobat or Adobe Reader (or other PDF viewer) to display with
the generated PDF. Select Page only to leave the tabs area to the left of the PDF pages empty. Select Book-
marks and page to display the contents of the Bookmarks tab (you use data selection objects to create book-
marks in PlanetPress) alongside the PDF pages. Select Page tab and Page to display the content of the Pages tab
(thumbnails of each PDF pages) alongside the PDF pages. Select Full screen to hide all screen contents except
the PDF page, and expand the PDF page to the maximum size it can occupy onscreen.
