Therfore, check carefully for accuracy to avoid this costly and time-consuming procedure. Photographs intended for halftone reproduction must be good glossy original prints, of maximum contrast. A computer printout of more than several lines should not be embedded in the manuscript, but treated as a figure. Because the printout will be photographed as line art, it should be a clear, sharp printout produced on a high-quality laser printer. Photographs for halftone reproduction should be about twice the desired size.
Limit tables to one per page.
Avoid the use of vertical rules in the tables. Alternatively, equations may be typewritten on a separate page, with their designated positions specified in the text. For manuscripts with extensive equations, TEX is the preferred word processing program. All sources cited in the text must be included in the reference list, and vice versa. The full list of references should appear on a separate page at the end of the paper.
