Ans. (b) Dots per inch

Sol.
The full form of DPI in the context of digital images is Dots per inch. DPI is a measurement of the resolution of a printed image or digital scan. It indicates how many individual dots of ink or pixels fit into a one-inch space on a display or printed document. The higher the DPI, the sharper and more detailed the image will appear.

In printing, DPI measures the printer's capability to produce finer details in the printed image. For digital images, DPI is often used to indicate the resolution of the image when printed. For example, a 300 DPI image will print at higher quality compared to a 72 DPI image, which is typically seen in web images.

In general, higher DPI values represent higher print quality and greater detail, while lower DPI values may result in more pixelated or blurry prints.

Information Booster:

  • DPI is primarily used in the printing industry to define print quality and is also relevant for digital images when printed on paper.

  • For screens (like monitors or smartphones), the term PPI (Pixels per inch) is more commonly used, but DPI is often mistakenly used interchangeably with PPI.

  • Typical printers use DPI values ranging from 300 to 1200 DPI, with 300 DPI being standard for high-quality prints.

  • When scanning images, DPI indicates how many pixels the scanner captures per inch of the original document.

  • Digital image editors, such as Photoshop, allow you to adjust the DPI settings to ensure proper print resolution.

  • For web images, a lower DPI like 72 DPI is usually sufficient because screen resolution is lower than print resolution.
