Illustration guidelines

Illustrations should be suitable for black and white reproduction. When your article has been accepted for publication, images should be supplied separately from the text of the article, i.e. not embedded into Word files.

Reference copies of all illustrations should be supplied (the images imbedded in the Word file is acceptable for this).

Illustrations created on a computer i.e. graphs maps and figures, should be supplied as one of the following:

For files created in a spreadsheet, the spreadsheet file with all source data accessed locally should be supplied, i.e. not referencing data from files that have not been sent. Graphs should have the figure number and caption as the graph title to avoid any confusion and any key/legend information should be placed at the bottom of the graph.

If there is any doubt contact the Articles Editor for clarification.

Pictorial illustrations wherever possible should be originals. Digitally supplied files should be 300dpi tif or high resolution jpeg files at the size of final reproduction (16cm wide), but do not increase image sizes artificially as this can produce unusable files. If files are larger than this leave them at the larger size: do not reduce them. If there is any doubt send a sample to or contact the Articles Editor for clarification.

If the publication is to have colour images/illustrations, treat them exactly the same as above but supply at 400dpi.
