I don’t - watermarks are generally added by copyright holders, and are
there to help protect their copyrights.

If the doc is already a Office doc, you can obviously easily do so there and export as .pdf

Otherwise you could use gimp

Well, in that case the PDF should be protected against modification, and
the the correct password set. If there is no password, modification is
allowed.

However, I haven’t seen any PDF with those watermarks, so I have not
investigated whether it is possible to remove them.

Maybe… I get some receipts/invoices with what may be a watermark, the
word “duplicate” shown in very big letters along the diagonal. It is
certainly a nuisance, and it is not protected by copyright. However,
some of the documents are legally signed (cryptographic certificate),
so editing them in anyway, although legal, would invalidate the
signature. However, one might want to remove the mark prior to printing
it, for reasons of readability (the printed copy has no legal validity,
anyway).

“should be” doesn’t matter. A failure on the part of the PDF producer to
properly secure their document doesn’t eliminate the copyright on the
document.

At least in the US, yes, they are protected by copyright - there’s an
implied copyright. The utility of that copyright, say, on a receipt or
invoice is perhaps dubious, but the course of action in that case is the
same - ask the person who sent you the watermarked PDF to send you one
without the watermark.

The OP’s best course of action is to talk to the producer of the PDF and
request one that does not have the watermark.

IMO, and as far as I’m concerned, if the flag for “no modification” is
not set in the PDF, then the producer doesn’t care if you modify it.

But not in Spain. Thus don’t assume that removing the watermark is
illegal for the OP (I have no idea where he lives).

I prefer to recognize the rights holders intentions rather than punish
them for technical incompetence. I don’t see what’s so hard about
respecting the rights holder’s rights.

But this isn’t the place for this argument.

And even still, the easiest solution is to ask the original creator to
create a version without the watermark.

Yes, but if there is no copyright notice, and they didn’t set the “no
modify” flag, then it is free to modify.

I can’t guess their intentions.

In an ideal world, yes. Go ask the talking heads of the electricity
supply company and request an invoice without the watermark for
printing. They never know a thing, and have orders to do nothing for
you. Thus, if I need it, I’m proactive.

If they put a watermark on it, they put it there for a reason.

But again, not the place to argue about this. Drop it.

Fine, whatever.

The watermark may just say DRAFT

The issue here is that you have decided that the OP is intending to
break the copyright and refuse to answer his question and help him on
that, unproved, basis. :frowning:

Which is there for a reason - and also, if that were the case, asking the
producer to provide an unwatermarked version would absolutely be an
option. There again, the author would have a reason for the watermark,
and access to the original is something that would be useful.

No, the OP hasn’t told us his intentions, and without more information
about his intentions, there’s no incentive to provide assistance. Most
people who ask vague questions like this tend to be trying to hide
something. If you had asked a question about your invoices, for example,
I doubt that you would have said “I have a watermarked invoice that I’m
having trouble reading, and removing the watermark would really help -
can someone help me do that?”.

Now, again, rather than continue to argue - drop it.

If money is “software” you could pay off the copyright holder of the document.

Just an idea.

Can I remove a watermark from a pdf? Maybe… but you don’t want that really do
you? Which is to say anything is possible. And that’s the only hint I’ll give out.

Adobe Acrobat (not the reader, but the full suite, Windows only) claims
to do it. It is legal software, not a hack, from the designers of PDFs.
Found it by googling, in minutes. Whether using a tool (like a knife or
a screwdriver) is legal would depend on each case. I have never tried,
anyway, I don’t own that software. I do have a test PDF from myself,
with sources, though :wink:

Terrible sorry both of you!!! I thought I would receive an email when someone answer my post but I haven’t receive anything. I thought nobody answered!!!.

This is the link I wanted undermark http://www4.tecnun.es/asignaturas/Informat1/AyudaInf/aprendainf/cpp/basico/cppbasico.pdf
It is a handbook for learning basic C++, it is from Tecnum (Technological Campus of University of Navarra). I want to print. Theoretically it is for learning but how it is possible learning with a watermark soooooooooo big???:frowning: The copyright only says the document must use only for personal no-commercial use even printed is allowed:). Banned is only commercial use.
I copy literally

But I have found something strange… looking in the Mechanical Mathematics department of University of Navarra.

http://mat21.etsii.upm.es/ayudainf/aprendainf/Cpp/manualcpp.pdf

It is exactly the same document without watermark!!!. In other department of the same university! lol!

Thank you all of of yourotfl!

That is normaly the case. but it is defined as such in your personal settings on the forums. Thus you better check.

When people answer via the nntp gateway, it is possible you don’t
receive any email.

Yep. (jovar).

Well, it is password protected, and all changes are disallowed. Even
writing comments, which is something that surprises me in a text for study.

Well, unless you pasted the wrong link, the documents are quite
different. The table of contents are different, and the first chapter is
different. I didn’t look further.

Well, not exactly :slight_smile:

The second document was written by people of the same university
(Navarra), yes, but it is available at a link of the Universidad
Politécnica de Madrid (upm.es), which I believe is quite more open :wink:

(the original source site of the people that wrote the second linked
document is dead and on sale)

The first document is an entry course, and the second one, quite older
in fact, is a more advanced course. So no, they are not the same document.

In fact, the last sentence of the first document says: “Si ha llegado
hasta aquí, puede pasar al segundo manual: Programación Orientada a
Objetos” (if you got here, you can move on to the second manual: Object
Oriented Programming), which is, I think, a reference to a more recent
edition of the second document.
