Figures

How to supply figures

Figures must be prepared electronically. Make sure that the image is of high quality when printed (in black and white) and is of high enough resolution (min. 300 dots per inch). We accept EPS, TIFF, PNG, PDF, and JPEG files. In any case, send us your illustrations in their original format (PNG, JPEG, etc.), do not reprocess them yourself.

All lines should be heavy enough (min. 0.75 point) and all figures, decimal points, symbols, etc., large enough and sufficiently spaced to ensure clarity when printed at the final size. If using colour, please ensure that the figure prints clearly in greyscale and adapt your text knowing that the difference between coloured items when reproduced in grey is not obvious.

As already mentioned, before using material such as illustrations taken from other sources, do not forget to obtain permission from the copyright holder and to correctly cite the source in your manuscript.

Positioning and layout

If you are using Word, you can include figures in the in the text as a ‘place holder’, but the graphic files for each of the individual figures must be provided separately.

Figure captions

Figure captions should be brief and placed centrally below the illustration, e.g., ‘Fig. 3: A short title’. No full stop is necessary unless the caption is more than one sentence long, in which case full punctuation should be used and the caption should be justified. Captions should be typed in point size 10.

References to figures

All figures must be referred to in the text in consecutive numerical order and should, for example, be referred to as ‘Fig. 3, Figs. 3–5’, or ‘Figure 3’ at the beginning of a sentence. Figures with several parts are cited as follows: ‘Fig. 2(a) and (b), Figs. 3(a)–(c)’. Figures and illustrations should follow the paragraph in which they are first discussed. If this is not feasible, they may occur on the following page.
