Dots per inch (DPI, or dpi [1]) is a measure of spatial printing, video or image scanner dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch (2.54 cm).
Dot pitch may be measured in linear units (with smaller numbers meaning higher resolution), usually millimeters (mm), or as a rate, for example, dots per inch (with a larger number meaning higher resolution). [3] Closer spacing produces a sharper image (as there are more dots in a given area). [4]
Modern inkjet printers can print microscopic dots at any location, and don't require a screen grid, with the metric dots per inch (DPI). These are both different from pixel density or pixels per inch (PPI) because a pixel is a single sample of any color, whereas an inkjet print can only print a dot of a specific color either on or off.
The resolution of computer screens is often denoted in millimetres pitch, whereas office printers are usually denoted reciprocally in dots per inch ('dpi', 'd/in'). Phototypesetters have long used micrometres. To convert dpi resolution to μm resolution, the formula to be used is 25400 ⁄ R, where R is the resolution in dpi. So for example 96 ...
Lines per inch (LPI) is a measurement of printing resolution. A line consists of halftones that is built up by physical ink dots made by the printer device to create different tones. Specifically LPI is a measure of how close together the lines in a halftone grid are.
Paint dots at head height mean the tree needs pruning. “Basically, it marks the tree in an inconspicuous way,” says Ken Fisher, assistant forester for the Boulder Parks and Recreation Department.
The measures "dots per inch" (dpi) and "pixels per inch" (ppi) are sometimes used interchangeably, but have distinct meanings, especially for printer devices, where dpi is a measure of the printer's density of dot (e.g. ink droplet) placement. [13]
