On leaflets or posters about events, keep essential information about time and place grouped together. White boards are easier to read when the writing is in colour. Use print rather then joined writing on boards. Notice boards positioned at an angle are often easier to read. Alternative ideas for presenting information.
Flow charts are ideal for explaining procedures.
Pictograms and graphics help to locate information. Lists of 'do's and 'don'ts' are more useful than continuous text to highlight aspects of good practice. Provide a glossary of abbreviations and jargon. Include a contents page at the beginning and index at end. Numbered bullet points.
