- [Instructor] Printed images generally require higher resolution than images for video or web. Additionally, the way resolution is handled is different for print. A printed image has a fixed physical size that is independent of its resolution or pixel dimensions. The printed size of an image is controlled by a numerical setting within the file, the pixels per inch, or PPI. This is sometimes confused with DPI, or dots per inch. DPI measures the dots per inch of printer ink or toner. A dot of toner or ink is not a pixel. A pixel is usually composed of many dots, so DPI values are usually higher than PPI values. An image at 600 PPI will print out the same size on a printer with 600 DPI and a printer with 2400 DPI. Some 3D rendering apps provide a handy tool to calculate print sizes, but designers and engineers still need to know how PPI works. When a bitmap image is printed, each pixel must have some size. It must take up some area on the page. An image with a fixed resolution prints…
