hello wena
i just made a cover template for you.
here is it:
http://db.tt/0Cw57beA – it's a scribus1.4.0rc6 file.
i can't do this every time – please try to compare this with the informations from the ls pdf, next time you should do your own setup…
the red frame is the final cover.
pictures or background colors should reach the black one (bleed).
the green frames (safety areas) are on a separate layer, called 'safety margins' – you may uncheck or delete it, when the work is finished (in preview mode it disappears and it won't print anyway…)
good luck
utnik
