The printout turns out to be the same size as the original, though its size on the monitor is different |
When the resolution of an image is raised, its screen size increases accordingly. However, the size of the image does not change when it is printed out; only the resolution changes. |
The unit for representing resolution is dpi (dot per inch) and represents the density of the image rather than the size. |
When images of the same size with two differing resolutions are printed, the printout quality of an image with lower resolution is poorer than that with higher resolution. |
For instance, when the same image imported at 72 dpi and 144 dpi is shown on the monitor, the size of the latter will appear twice that of the former. Nonetheless, when both are printed, the printout size will be the same. However, the latter image quality will be better. |

The size of the image on the screen differs from that of the original image; the size of the printout remains the same, but the printout quality differs from the original. |
