NEVER EVER say to your audience: "I AM SORRY YOU CAN NOT READ WHAT IS ON THE VIEW-GRAPH, BUT........ bla, bla, bla".

You are wasting your audiences time, you are showing your incompetence as a presenter and disrespect for your listeners.

Do NOT READ OUT word for word what is in your view-graph (your audience can read). Use KEY-WORDS and talk around these words. Key-words are your and your listeners guide through the presentation.

A direct copy of a page from a report or from a large drawing gives in 99 out of 100 cases not a good view-graph as the print is too small and too much and irrelevant information is shown. It shows you are not worried about quality!!

Data that are not relevant should not be in a view-graph. In 9 out of 10 cases the third significant figure in any number shown falls in that category (see wisecrack on numbers)

Avoid light yellow lines or dots on a white background and black lines or print on a dark blue or dark red background as these are difficult to see.

Keep view-graphs simple. If in a flow scheme one element is the one you talk about then draw all other elements with shaded lines and the important part in fat lines.

Make gas lines thinner than liquid lines and/or use different colours.

Take the view-graph out of its plastic folder, you keep it in for storage, when you present it. If presented in the folder your view-graph becomes darker and less clear.

Switch off the light near the projection screen or directed at the screen.

Focus your view-graph projection machine.
