Lines should not be thinner than 0.25 pt. Please avoid shading or elements filled with patterns in the figures as much as possible. If shading is necessary, please note that the shade will darken considerably when reducing the figure. Different types of shading must, therefore, be very distinct. Freehand or typewritten lettering is not acceptable.
Place legends on a separate page.
Photographs Photographs should be in black and white or in color on glossy paper. Photocopies of photographs are not acceptable. It is preferred to have no screens in the photographs. Slides are acceptable, but are not preferred. Photographs should be large enough to permit reduction to the specific journal size without affecting legibility.
