Figures, graphics, images & cover artworkFigures & graphics • Colour figures may be used free of charge both online and in print (we use CMYK colour model). • Figures should be supplied as TIFF files, with a resolution of 600 dpi or greater. You can supply EPS files instead, but we will need to convert these to TIFF files in the final article. • Files should fit within either single column (8.3 cm) or double column (17.1 cm) width, and must be no longer than 23.3 cm. • Schemes and structures should be drawn to make best use of single and double column widths. • Figures including logos, trademarks or brands names (for example Lego® or Rubik’s Cube®) should not be used. You must obtain permission to use any figure or graphic belonging to someone else; see our guidance on using third party material in Royal Society of Chemistry publications.
