Inserts are additional pieces of information or materials added to a primary document or product. They can include brochures, coupons, or advertisements that provide extra details or promote related items. Inserts are commonly used in magazines, packaging, and direct mail to enhance the main content and engage the audience. In the context of printing, inserts can be printed separately and then placed into a larger publication. This allows for targeted marketing or the inclusion of time-sensitive information without reprinting the entire document. Inserts are a cost-effective way to deliver supplementary content to consumers, such as promotional offers or event announcements.
