Print and Paper Print Style and Size Print should be in an upright sans serif typeface of medium weight, with simple but clear character definition. Light print should be avoided. Type should be set in the largest size that circumstances will allow, with a minimum of 8 point. Lower case print is much easier to read and should be used almost exclusively. Clear numerals are very important, in particular to avoid confusion between numbers such as 6 and 8, or 3 and 5.
Legibility depends upon text spacing.
Thin, flimsy, glossy or coated paper should not be used. Pale yellow is the best alternative to white. Print Colour Print should be black. If it is absolutely necessary to use other colours, intense blue or brown are acceptable alternatives, but red and green should be avoided. Background Grey shading and coloured tints, other than pale yellow, should be avoided.
