Printing Devices Resolution (dpi)

Dpi (dots per inch) - the number of pixels per inch. This unit is used to determine the resolution of the images generated by the printers, plotters, imagesetters, etc.. It describes the level of detail rendering of the image in a computer-controlled printing devices, highlightning, as well as cutters, engraving, etc.

Dpi unit determines the density possible to grasp the details of the image, which are understood as a set of pixels whose centers are in fixed positions relative to each other and arranged in rows and columns form a matrix. Horizontal resolution (in rows) is the actual resolution of the device, and unless specified otherwise, is also vertical resolution.
