What are common methods used in document binding?

The correct answer highlights common methods used in document binding that are not only diverse but also widely utilized in both professional and personal settings. Plastic binding, wire GBC (which stands for GBC binding, a brand known for its wire binding systems), and thermal binding are popular techniques because of their effectiveness in securing pages together while allowing for a polished and professional appearance.

Plastic binding involves using a plastic comb that slides into punched holes along the edge of the paper, allowing the documents to lay flat when open. Wire GBC binding uses a double looped wire that gives documents a clean, finished look. Thermal binding involves the use of heat to adhere the pages together, creating a seamless spine. These methods are preferred in various industries for their durability and the aesthetic edge they provide.

The other choices either limit the scope of binding methods or are overly restrictive. For instance, digital and print formats refer more to the mediums of documents rather than binding techniques. Focusing solely on manual methods disregards the advancements and options available that enhance usability. Lastly, pasting and stapling are only basic methods and do not encompass the range of modern binding options that are commonly used today. Thus, the correct answer accurately represents the comprehensive nature of binding methods used in document preparation.
