Printer centric: Select to have PlanetPress Design execute the preview as if the document were run on the printer
itself. Note that for screen previews, documents are always physically run on the host on which you are running Plan-
etPress Design.
Optimized PostScript Stream: Select to have PlanetPress Design execute the preview using the Optimized Post-
Script Stream option. Note that the external images included in the document must reside in a folder on the host on
which PlanetPress Design is running. Obviously the PlanetPress Talk expression you entered in the Image box for each
of the dynamic images that reference external images, must resolve to the correct pathnames for the external images
in the preview environment.
6. Select the PostScript interpreter you want to use in the PostScript interpreter group.
Internal interpreter: Select to use the PostScript interpreter built in to PlanetPress Design.
System default: Select to use the PostScript interpreter your system uses as its default. Note that this option will use
whatever application is associated with the .ps extension to create the preview file. If this application is not able to per-
form postscript conversions and to generate PDF files, the preview process will fail. If using the Opacity option in any
object's properties, check the Allow PDFTransparency so that the opacity will be taken into consideration.
7. If your document uses database emulation, set the refresh option.
Refresh data from database: Select to have PlanetPress Design refresh the sample data file by repeating the SQL
query before creating the preview. Clear to have PlanetPress Design use the sample data file in its current state. This
option is available only when your document uses database emulation.
Refresh Metadata: Select to have PlanetPress Design refresh the metadata file before creating the preview. Clear
to have PlanetPress Design use the metadata file in the current state, without regenerating it.
8. Click OK.
PlanetPress Design closes the Preview dialog box, performs the preview, and displays the resulting PDF file.
The Objectif Lune watermark appears on all on-screen previews, unless an activated installation of PlanetPress Pro-
duction can be found on the same computer or another computer on the same network subnet.
If you are using color management, recall that color in on-screen previews may not match color in printed output. The color
settings of the PDF viewer you use for on-screen previews determine the color in an on-screen preview of a document, and
thus whether that color matches that in the printed output.
Previews of Documents that Use ASCII Emulation
What should I know about previews of documents that use ASCII emulation?
If your document uses the ASCII emulation, the appearance of any hard copy and on-screen previews you perform may differ
from the appearance of the document in the Page area of the PlanetPress Design Program window. The following describes
why and when this discrepancy can occur.
Discrepancies can occur when the PostScript interpreter that performs the preview and the internal code that displays the doc-
ument in the Page area, do not have the same Read in binary mode setting. Thus discrepancies can occur in any of the fol-
lowing three cases.

PlanetPress Design displays the document in the Page area with data in which it has per-
formed end of line character replacements, while the printer prints the document with
data that has not had any end of line character replacements.
