Here's a quick overview (covered in more detail in the help files):
- Select File | Prepare File for Printing Service... | Create File in PostScript...
- Click the desired Printer/Printer Driver (if not already selected).
- Make sure the Print File box is checked.
- Click the Properties tab and change any default settings if needed.
- Click OK
- Give the file a name
- Click OK
- Publisher creates a PostScript file.
Additional considerations:
Print Color Separations. When preparing a spot color publication print a separate proof for each color (to make sure that objects will print in the desired color). All pages will print in B/W but only objects on the page for each color (black/gray, spot color 1, spot color 2) will print on that separation. Choose "Print Color Separations" on the Print Dialog screen.
