Line drawings must be inked and clearly labeled, or figures may be created using graphics software and submitted on disk as well as hard copy. Save computer graphics in EPS format. Check with the editor or graphic designer before submitting computer-drawn figures. Halftones should be clear, sharp, and of high contrast. They may be submitted as slides or glossy prints.
Slides are preferred, especially for color printing.
If prints are submitted, they should be printed on glossy paper and under no circumstances should they have any writing on them. Photographs may be labeled on the back and mylar or onionskin paper overlays may be attached to show necessary linework. Photographs taken with a digital camera are discouraged unless resolution is 300 dots per inch. The complexity of an illustration is inversely related to the percentage of reduction possible. This consistency in proportional size of figures is important in keeping the cost of the publication down.
