Illustrations and tables
Supply tables, figures and plates on separate sheets at the end of the article, with their position within the text clearly indicated on the page where they are introduced. Provide typed captions for all tables, figures and plates (including sources and acknowledgements) on a separate sheet. Tables produced in Microsoft Excel format should be typed in either Courier, Times New Roman or Arial fonts.
The journal is printed in black-and-white. Therefore, we prefer that you supply your figures in greyscale. Figures supplied in colour will be converted to greyscale for print unless the author confirms they will cover the cost of printing in colour (costs available from the production/editorial office). You may however request for any/all figures to be shown in colour in the HTML (web) version of your article, but bear in mind that the PDF/print version will still be black-and-white, so please make sure that colour is not critical to understanding any figures; and do not describe elements of the figure in terms of their colours. For example line graphs with several data series can usually be represented adequately in black-and-white by using different line styles and/or different shaped nodes.
Present tables with the minimum use of horizontal rules (usually three are sufficient) and avoiding vertical rules except in matrices. It is important to provide clear copies of figures (not photocopies or faxes) which can be reproduced by the printer and do not require redrawing. Photographs should be preferably black and white glossy prints with a wide tonal range.
