I wrote a postscript printer driver a little while back, so I should be able to figure out what form this will take - I'll post an answer when I've worked it out. Tom (alternatively, if you have distiller and have time to play, do something like create a document containing one character and save it. Save a new copy with the attibutes that you want set and do a binary comparrisson of the two). sillyboy@mindless.com wrote: > Adobe Acrobat has built in security features that allow restrictions on specific actions, > including selecting text, editing the document, printing, etc...
