Desktop publishing (DTP) is the process of creating and designing documents using a personal computer and specialized software. The software used in DTP is known as page layout software, and it allows users to create professional-quality documents such as brochures, newsletters, magazines, books, and more. The software allows users to combine text, graphics, photos, and other elements to create visually appealing documents.

DTP software is often used by graphic designers, marketers, publishers, and other professionals who need to create high-quality, print-ready documents. The software provides a wide range of tools for designing and formatting text, images, and other elements, including options for color, typography, and layout.

Examples of DTP software include Adobe InDesign, QuarkXPress, and Microsoft Publisher. These software often have the capability to work with other software such as Adobe Illustrator and Photoshop to create more complex and interactive documents.

With the rise of digital publishing, DTP has also been used to create digital publications such as eBooks, interactive PDFs, and digital magazines that can be viewed on various devices such as computers, tablets, and smartphones.
