The reverse cover in printing refers to the pattern and content on the reverse side of printed matter. The front of printed matter is usually eye-catching contents such as selling points, slogans and main pictures, and the back may be some details, supplementary explanations or blank backgrounds. However, this does not mean that negative factors are less important than positive factors. In fact, correct reverse design can improve the overall quality and impression of printed matter and leave a better impression on readers.

The reverse design of printed matter can have many elements, including colors, patterns, characters and so on. Among them, the use of color is very important, because it can arouse readers' emotional response and attention. Some people will choose the opposite background color to correspond to the front to achieve the consistency of the overall effect; Others will use bold negative colors to attract readers' attention, but they should also be careful not to be too fancy.

The content presented on the reverse side of printed matter also needs careful planning. Some printed materials will add some additional information or related tips on the reverse side, so that readers can better understand and use printed materials. At the same time, related contact information or brand information can also be placed on the reverse side to expand the publicity effect. In a word, the back cover plays an increasingly important role in printed matter design, which requires us to pay more attention and energy.
