We did something very similar with our invoice:

1. create a blank invoice form in postscript
2. convert 40 page ascii file into 40 individual postscript file
3. watermark the form onto each postscript invoice page
4. combine the postscript files back together into one big one for
printing/faxing.

The 'wartermarking' is done in #3, using this simple little perl script:

-------------

#!/usr/bin/perl

open(DOD, "$ARGV[1]");
$flag = 0;
while (<DOD>) {
    if (/^%%Page:/) {
        if ($flag) {
            print "grestore\n";
        }
        $flag = 1;
        print $_;
        print "gsave\n";
        #print ".99 setgray\n";

        &watermark();

        print "grestore\n";
    } else {
        print;
    }
}
close(DOD);

sub watermark {

  open (RPT, "$ARGV[0]");
  while (<RPT>) {
    print $_;
  }
  close (RPT);
}


---------------------------

It's some basic simple postscript search and replace...
