What kind of Image Files can I upload ?

The following image formats are accepted:


  • TIFF (.tif) TIFF files should be saved using LZW compression or any other non-lossy compression method.
  • JPEG (.jpg)
  • EPS (.eps) EPS files can be uploaded upon acceptance


Image Size

Figure images should be prepared with the PDF layout in mind, individual figures should not be longer than one page and with a width that corresponds to 1 column or 2 columns.

  • All articles are prepared using the 2 column layout: 2 column articles can contain images 85 mm or 180 mm wide.


Resolution Requirements

All images must be uploaded separately in the submission procedure and have a resolution of 300 dpi at final size. Check the resolution of your figure by enlarging it to 150%. If the resolution is too low, the image will appear blurry, jagged or have a stair-stepped effect.

Please note saving a figure directly as an image file (JPEG, TIF) can greatly affect the resolution of your image. To avoid this, one option is to export the file as PDF, then convert into TIFF or EPS using a graphics software. EPS files can be uploaded upon acceptance.


Color Image Mode

Images must be submitted in the color mode RGB.


Figure and Table Legends

Figure and table legends are required to have the same font as the main text (12 point normal Times New Roman, single spaced). Legends should be preceded by the appropriate label, for example "Figure 1" or "Table 4". Figure legends should be placed at the end of the manuscript (for supplementary images you must include the caption with the figure, uploaded as a separate file). Table legends must be placed immediately before the table. Please use only a single paragraph for the legend. Figure panels are referred to by bold capital letters in brackets: (A), (B), (C), (D), etc.
