Artwork

 

 

Electronic Figure Submission

• Supply all figures electronically.
• Indicate what graphics program was used to create the artwork.
• For vector graphics, the preferred format is EPS; for halftones, please use TIFF format. MS Office files are also acceptable.
• Vector graphics containing fonts must have the fonts embedded in the files.
• Name your figure files with "Fig" and the figure number, e.g., Fig1.eps.

 

Line Art

• Definition: Black and white graphic with no shading.
• Do not use faint lines and/or lettering and check that all lines and lettering within the figures are legible at final size.
• All lines should be at least 0.1 mm (0.3 pt) wide.
• Scanned line drawings and line drawings in bitmap format should have a minimum resolution of 1200 dpi.
• Vector graphics containing fonts must have the fonts embedded in the files.

 

Halftone Art

• Definition: Photographs, drawings, or paintings with fine shading, etc.
• If any magnification is used in the photographs, indicate this by using scale bars within the figures themselves.
• Halftones should have a minimum resolution of 300 dpi.

 

Combination Art

• Definition: a combination of halftone and line art, e.g., halftones containing line drawing, extensive lettering, color diagrams, etc.
• Combination artwork should have a minimum resolution of 600 dpi.

 

Color Art

• Color art is free of charge for online publication.
• If black and white will be shown in the print version, make sure that the main information will still be visible. Many colors are not distinguishable from one another when converted to black and white. A simple way to check this is to make a xerographic copy to see if the necessary distinctions between the different colors are still apparent.
• If the figures will be printed in black and white, do not refer to color in the captions.
• Color illustrations should be submitted as RGB (8 bits per channel).

 

Figure Lettering

• To add lettering, it is best to use Helvetica or Arial (sans serif fonts).
• Keep lettering consistently sized throughout your final-sized artwork, usually about 2–3 mm (8–12 pt).
• Variance of type size within an illustration should be minimal, e.g., do not use 8-pt type on an axis and 20-pt type for the axis label.
• Avoid effects such as shading, outline letters, etc.
• Do not include titles or captions within your illustrations.

 

Figure Numbering

• All figures are to be numbered using Arabic numerals.
• Figures should always be cited in text in consecutive numerical order.
• Figure parts should be denoted by lowercase letters (a, b, c, etc.).
• If an appendix appears in your article and it contains one or more figures, continue the consecutive numbering of the main text. Do not number the appendix figures, "A1, A2, A3, etc." Figures in online appendices (Electronic Supplementary Material) should, however, be numbered separately.

 

Figure Captions

• Each figure should have a concise caption describing accurately what the figure depicts. Include the captions in the text file of the manuscript, not in the figure file.
• Figure captions begin with the term Fig. in bold type, followed by the figure number, also in bold type.
• No punctuation is to be included after the number, nor is any punctuation to be placed at the end of the caption.
• Identify all elements found in the figure in the figure caption; and use boxes, circles, etc., as coordinate points in graphs.
• Identify previously published material by giving the original source in the form of a reference citation at the end of the figure caption.

 

Figure Placement and Size

• When preparing your figures, size figures to fit in the column width.
• For most journals the figures should be 39 mm, 84 mm, 129 mm, or 174 mm wide and not higher than 234 mm.
• For books and book-sized journals, the figures should be 80 mm or 122 mm wide and not higher than 198 mm.
