Each pixel could be black, white, or any other color, but they are all next to each other with no spaces between them. Now think about 300 pixels in an inch of space. If you divide each dimension by 300, you will have the size of the image at 300ppi. It is however many pixels wide by however many pixels tall. The PPI is the display resolution - not the image resolution.Р”Р„ digital image is what it is. Pixels per inch (PPI) refer to the square pixels in a digital image, which are in contact with the adjacent pixels. Basically, 600 dpi printers print 600 tiny little dots across one inch and 600 dots vertically for one inch.Р”В®ven though 'dots per inch' (DPI) and 'pixels per inch' (PPI) are used interchangeably by many, they are not the same thing.

Most printers print the same number of dots horizontally and vertically, though some may have differing numbers. It is the measure of how many dots of ink or toner a printer can place within an inch (or centimeter). Color photographs are printed using four inks, Cyan, Magenta, Yellow, and Black (CMYK), and four separate dot patterns, one for each ink.Р”ВPI is probably the most familiar and most misused measure of resolution. Printed dots have space between them to make white, or no space between them to make black. Dots per inch (DPI) refer to printed dots and the space between them. Traditional printing methods use patterns of dots to render photographic images on a printed page. There is a lot of confusion between DPI (dots per inch) and PPI (pixels per inch).
