In printing, what does DPI stand for?

The correct option is (2)

Dots per Inch

Key Points

• Dots per Inch, or DPI, refers to the number of ink droplets that a printer will discharge per inch when printing an image. When printed, a photograph will have more information visible the more dots per inch it contains.
• An image will appear clear and crisp at 300 pixels per inch (approximately equivalent to 300 DPI, or dots per inch, on a printing press). These photos are regarded as high-quality, or high-res.
• All picture and art files should have a resolution of 300 dpi in order to be printed. It is the industry standard since the offset press cannot accurately reproduce resolutions higher than 300.

Additional Information

• A pixel, also known as a picture element, is the smallest unit of data used in digital imaging.
• A 2-dimensional grid of squares is used to illustrate the arrangement of pixels. Every pixel serves as a sample of the original image, with more samples often yielding more accurate renditions of the original.
