The centrefold poster was causing me problems until the final minute. I had an A3 version which i was ok, with but when blown up to actual size (slightly larger than A2) it looked clumsy and rushed. spent most of the night before the print deadline redesigning it and thankfully I'm pleased with it now (bottom image). Just finalized the order for 50 copies. Did a trial run of full size prints on the plotter first and realized that the backgrounds were far from white so had to play with levels for a while to avoid a difference in tone between the images and the borders.
