Correct option is D
A gutter margin is an additional space added to the inner margin of a page layout, compensating for the part of the paper that becomes unusable due to the binding process. When pages are bound together, a portion of the inner edge of the page is lost in the binding, making it harder to see or read text near the spine.
- Binding Process: When books or documents are bound, a portion of the inner margin is covered by the binding, making the gutter margin necessary to ensure no content is lost.
- Use in Booklets: Gutter margins are typically larger for documents that have thicker bindings, such as books or large reports.
- Difference from Other Margins: A wide margin refers to the general space on all sides of a page; a mirrored margin refers to symmetrical margins on opposite pages in a two-page spread; and a narrow margin refers to small margins all around the page.
Additional Information:
- Wide margin: A wide margin is a general term for a larger-than-usual margin.
- Mirrored margin: Mirrored margins refer to a design where the left and right pages have identical margins.
- Narrow margin: A narrow margin simply refers to a smaller margin around the page.
