Electronic Artwork
When creating illustrations, use font sizes and line weights that will reproduce clearly and accurately when figures are sized to the appropriate page size. Preferably use the Adobe font Helvetica for labeling. If you use blends (degradés, vignettes, gradients, fountains), use no more than 10 in one file. When using rules, never use a rule weight less than .25 point, preferably .5 point.
For black and white line art, use solids, cross-hatching, or dot patterns rather than screen tints when possible. Do not use "electronic whiteout" (delete unnecessary elements from an illustration; never use a white box to cover them up).
Always consider the final reduced size of an illustration. The final size of figures must fit within a 4˝-by-7-inch text page. The final size of type in an illustration should range from 8 point to 12 point; the ideal size is 10 point. When saving the final illustration, save it at the final size and orientation to be used in publication.
If it is necessary to export graphics from vector-based drawing programs (e.g., Adobe Illustrator) to raster-based programs (e.g., Adobe Photoshop), a resolution of at least 600 dpi is required for quality reproduction. When scanning art for publication, a resolution of 600 to 1000 dpi at final size is preferred for line art and at least 300 dpi for halftones (photographs).
Do not use color for shading in line art that is otherwise black and white. For economic reasons, the vast majority of illustrations are printed in black and white or grayscale. The presswork for color illustrations is prohibitive and the cost ($1000 per page of color) must be borne by the author; however, it is possible to use color art in the online publication.
In the event that color is used, artwork must be as CMYK color. (In printing, the four inks used to produce color are cyan, magenta, yellow, and black [CMYK], known as four-color separations.) RGB (red, blue, and green used to create color images on your monitor) must be converted to CMYK and all necessary color adjustments must be made prior to transmitting the files.
The files for graphics must be large—generally more than 1 megabyte at the least—and should not be scanned from already published material.
Do not include figure legends in a graphics file. Figure legends should be placed after the Reference section as text in the main manuscript text file.
Do not embed graphics within the text files, even if your software enables page makeup including the graphics. Do not compress files. Graphics must be supplied separately in EPS or TIFF format (preferred), with one illustration per electronic file.
Do not prepare JPG or PowerPoint files, as Manuscript Central will not accept them. They do not reproduce well in print.
The Blackwell Publishing Web site contains extensive and clear instructions on how to convert files from various unusable formats such as PowerPoint. You can access this at Blackwell Publishing Author Resources.
