DPI measurement in printing. The DPI (dots per inch) of an image is simply metadata embedded inside the image (header). The actual quality ( resolution ) of the image (within the file itself) is not affected when its DPI value is adjusted. The DPI value is read by some devices (such as printers) to determine how your image should be presented on a medium (such as paper).
Resolution : Resolution is the measure of pixels in the display, usually expressed in measurements of width x height.
Higher resolution means more detail. Again this is a badly misused term, the resolution of a digital photo are its pixel dimensions and technically high resolution would refer to the resolving power of the pixels, the number of pixels mapping real world dimensions in the field of view of the photo. Deliver an image in 7 3or 4DPI? What is the difference and how to do the conversion? Find out the truth about DPI in this article.
Thus, we have a resolution of 2. If we’re talking printing paper, and a printer is able to. Printer resolution is measured in ink dots per inch, also known as dpi.
