DTP stands for Desktop Publishing. Simply DTP uses page layout software on personal computers (desktops) or computer systems to design, build and edit documents. DTP deals mainly with the production of print publications. More recently, DTP has also been active in the development of various online content forms.

In order to become a DTP operator, computer application expertise, relevant hardware (such as a printer) and relevant software must be acquired (page layout software).

Aspects such as typography, document layout (form) and document printing are taken care of by the DTP operator. DTP is not only limited to document processing, creation and printing. Printing items such as posters, business cards, circulars, announcements, sign-boards, packaging products, etc. are also involved.
