I decided to print my posters off on my A3 printer to see which I liked the best and if I need to make any changes to colour and the design. Despite my printer leaving lines on the majority of them I would say they turned out well, perhaps needing to lighten up the Purple/Red so it matches the other more brighter colours.

I like them all as a group, I think they will look very nice either together or in the same vicinity as each other. For example if they were put up in Uni one colour could be in one room, another in the reception etc. Because the logo is strong the colour just adds to the design still, recognised as one.
