Generally speaking, the quality of PPT needs to be considered from the following aspects: 1, format-whether the company VI system is correct, whether the theme content is correct and whether it is convenient for demonstration; 2. Structure-Is there a clear guiding system, such as opening animation, cover, preface, table of contents, transition page, inner page and ending? To be clear and easy to understand, the audience will not lose themselves on that page; 3, typesetting-the contrast between content and background should be obvious, the content should be aligned, the layout should be novel, the pattern should be comfortable, the color should be bright and so on. 4, animation-PPT without animation will be very dull, the audience can stare at the movie 1 hour does not feel long, but staring at a still picture for a minute will be tired; 5, multimedia-of course, adding as much music and sound as possible will be vivid, but not too much and too messy.
