In the perfect world this is what we need from you: An RGB 8 bit colour corrected, profile embedded, 360dpi, sized to print, tiff (with LZW compression), with the correct borders added. Maximum size is 1.1m on the short side and 25m on the long side.
Please try not to send a JPG file to us, other than being greeted with the odd snear or snide remark your prints will be less than optimal. Gradients will have slight steps in them and artifacting will be exaggerated. We warned you. :-)
This can be airfreighted, FEDEX'd, DHL'd, hand delivered, FTP'd, emailed or sent via Winston the homing pigeon.
