DPI Full Form- Dots per Inch

What is DPI? The full form of DPI is  Dots Per Inch. Dots per inch, or DPI, is the term used to describe how many ink droplets a printer will create while printing an image. When printed, an image that contains more dots of ink for every inch will have more detail. It is a measurement of the number of individual dots that could be arranged on a line inside an inch in spatial printing, video, or picture scanning applications. Dot gain, or the enlargement of the halftone dots during printing, is referred to as the printing resolution of a hard copy print and the resolution number of dots per inch in a computerized print.

What are the uses of DPI?

DPI is a measure of an image's clarity and detail on paper that is used in printer resolution. For photographers and designers, it's a crucial metric as it establishes the caliber of a printed item, such as a glossy magazine, poster, or brochure.
DPI is responsible for an image's sharpness and quality. The more ink droplets closely clustered together, the higher the resolution of the image.
The same holds true for scanning. Similar to a printer, a scanner's quality is determined by the DPI, or the quantity of data points that the computer and scanner extract from the image.
Additionally, DPI varies based on the printer. While some professional printers would need to print photographs at double the resolution of 300 DPI, the ordinary inkjet or laser printer can create images at least as high as that.
An image with a resolution of 300 DPI has 300 ink dots per inch on average. For printing high-quality photos, graphic designers and photographers usually use 300 DPI as a standard. Larger photographs, however, can call for an even greater resolution.
