We have an application that creates a PDF document from a Word/Excel files. The files are opened by the native application and printed to a postscript printer. Then Adobe Distiller is envoked to do the actual converison to a pdf file. By using the Prologue file, a watermark can be added to the pdf file (ie...Uncontrolled if Printed) but I have a couple of questions regarding pdf files and the postscript page definition language...
1) Is is possible to have the watermark only show when actually printed? Currently, when a watermark is added, it is visable even when the document is viewed.
2) What commands would be necessage to add to the Prologue file to include the current date (preferably the date the pdf file is printer/viewed)?
