We prefer figures to arrive as .tif files, although we can accept most figure formats. Please note that .jpgs generally do not meet our requirements and should not be sent. For production, electronic images must be at a minimum resolution of 600 dots per inch (dpi) for line drawings (black and white) and combinations, and 300 dpi for colour or greyscale. Colour figures must be supplied in CMYK not RGB colours. Please ensure that the prepared electronic image files print at a legible size and are of a high quality for publication. For useful information on preparing figures, visit http://cpc.cadmus.com/da where you can also test whether your figures are suitable for production by using the preflight tool at http://art.cadmus.com/da/index.jsp.
