Premium large format poster printing range from Northstar. Standard sizes include A3 to A0, PLUS 30″x40″ and 40″x60 sizes”. Whoever said size doesn’t matter was clearly talking nonsense. Of course it matters. Although it’s just as important as where you place your posters. Think about all the places your customers go: Your store, Your reception, Past your windows, Your waiting room, Your till point, Your warehouse. All of these are potential points of contact. They’re places you could talk to your customers… without being there. So whatever you’ve got to say, we’ve got a poster to suit.
