Improving Thumbnail Quality

Adobe Illustrator
This example covers Illustrator version 6, 7, 8,9 and 10.

Illustrator does not offer any options for modifying thumbnails in it’s native format (.ai). By default, Illustrator makes Bitmap PICT thumbnails at 128x128 pixels.

Right: Thumbnail in Illustrator on OS X, PDF Compatible

In Illustrator 10 on OS X, however, there are some important options. For the best catalogs, iView recommends that you should save files with the "Create PDF Compatible File" option turned on. This option makes the file you save a PDF file. This option is in the "Illustrator Native Format Options" dialog box, which appears when saving an Adobe Illustrator file using the "Save As' command.

If you save Illustrator files without this box checked, or as Illustrator EPS, you will need to install the Ghostscript extension (OS X download) into the iView Importers folder, in order for iView to catalog these file types. This extension can be found on the download page of iView’s web site.

In Illustrator 10 on OS 9, you will need to install the Ghostscript extension (OS 9 download) into the iView Importers folder to view any file type saved by Illustrator.

iView's "Rebuild Thumbnail" command will not improve the quality of this thumbnail.
