OK guys, I'm looking for some advice on how to create a poster with photoshop (CS3).
It's to publicise a club open day and will be a montage of road, MTB and CX shots which will be printed at A3 and A4 by a commercial printer.
The montage bit I'm fairly confident I can muddle through with but I need to know what initial settings are needed and what file format it should be saved in so I can present it to the printers in a ready-to-use state.
So far I've set the document size to A3, 300dpi, CMYK colour mode, 8-bit colour. Not sure if these are all correct or if I can just use one of the default colour profiles like "Photoshop 5 Default CMYK"
Any advice gratefully received (or I could just insist that someone does it all for me… :wink:)
