Photographs must be clear and printed on glossy paper with good contrast. Crop photographs to include only essential detail. If several photographs are used for a single plate, they should be grouped to fit the page width, with identifying letters. The caption should identify each photograph that occurs in a plate. Color photographs can be submitted but will be reproduced in black and white.
Photocopies are unacceptable.
Send artwork flat, unrolled. If originals are larger than the printed page, have them professionally reduced to the page size. Computer-generated graphics are acceptable if they meet professional standards. Typewriter lettering is not acceptable. Identify the top of each illustration.
