Yes, this sounds like what is going on. The Guardian either does
not know about this or are not prepared to give advice...
(perhaps they have commercial reasons not to badmouth Adobe?)

They are aware of the problem. And cheerfully note that the
problem is not evident in printing. I rarely print them. I use
the spare blank side of old A4's that have been printed with a
nice big grid and jot the numbers down with a pencil. It is not
hard to guess the lines...
