Preparation of Illustrations

Instructions To Authors
By the Editor of Geophysics
Revised January 2007

Preparation of Illustrations

If possible, design each illustration to be reduced to Geophysics column size to conserve space and reduce costs. The abscissa and ordinate of each graph should be labeled, and units should be denoted in parentheses. A title heading for each graph is encouraged; the first letter of graph labels should be capitalized; and the graph’s style, font, and format should be consistent with other figures. Be sure lettering within figures is legible and is not too large or too small. Labels on vertical axes should read from bottom to top when the page is held vertically (from left to right when you rotate the page clockwise 90°). All graph labels should use the same type font.

The body of illustrations should not contain titles or other textual material that can be placed in the caption. Exceptions to this rule will be considered only when clarity demands. Use standard Geophysics abbreviations in labeling scales (see the section "Examples of style for units").

To ensure high-quality reproduction, authors should make a diligent effort to provide the best possible original illustrations.

All illustrations must be submitted in electronic format. Illustrations submitted after the paper is accepted must be meet the following specifications:

All illustrations must be submitted in EPS or TIFF format with color and grayscale images at a resolution of at least 300 dots per inch (dpi) and line art of at least 600 dpi (1200 dpi is preferred). Submit each figure in a separate digital file, named according to the figure number. Do not imbed figures in documents. Do not submit figures in Microsoft Word, PowerPoint, or Canvas. Canvas files, especially the earlier versions of Canvas, are not stable when converted to the format necessary for printing. This can necessitate time-consuming and expensive manipulations.

Below are examples of the same figure in low resolution, unsuitable for publication, and in high resolution, suitable for publication.

Sample images

Please do not produce figures by making straightforward screen dumps of the graphic output of a software package. This usually results in unnecessary decorations, gray background, unreadable axes and labels, overlapping labels, or low resolution. If the software has no other way of generating graphic output, high-resolution screen-dump images are allowed as part of the figures if unnecessary details are removed, proper axes and labels are added, and consistent formats are used for similar figures.

The author's last name and the figure number should be included in the margin of each figure for identification. Indicate the correct orientation of the printed figure. Use an upward-pointing arrow to show orientation.

Color figures must be formatted using CMYK (cyan-magenta-yellow-black), not RGB (red-green-blue). Grayscale or black-and-white figures must be submitted in grayscale or black and white.

Permission to reprint figures and tables
Authors are responsible for obtaining permission to use figures and tables previously published in other books or journals. Letters from the copyright holders granting permission should accompany the manuscript. It is also the responsibility of the author to check reproduced materials against the originals for absolute accuracy.
