In those cases where this is impossible, the title and explanation of the figure or table may be placed on the reverse side of an immediately preceding blank page so that it faces the figure or table. However, the number of such a page must be adjusted on the blank side so that it conforms with the position of other page numbers in the rest of the thesis. More than one figure may be placed on a page which offers adequate space. Tables and figures may be placed in either portrait or landscape mode. Students should remember that microfilming is a black and white photographic process.
Colours appear as slightly varying shades of grey.
Thus, lines on a graph should be identified by labels or symbols rather than by colours. Similarly, shaded areas such as countries on a map have better contrast if crosshatching is used instead of colour. Wherever possible, professional photocopies made by a commercial printer should be used instead of photographs. When using photographs, each should have the full range of contrast from true black to pure white. Photographs with limited contrast will not reproduce satisfactorily on positive microfilm.
