Ever tried to print a picture from the internet and wondered why it's pixilated? On-screen resolution is different from print resolution. Our computer screens are set to 72 DPI (dots per inch).
*NOTE: To get a high quality print, it needs to be at 300 DPI or higher.
It's simple really.. Imagine a 1 inch by 1 inch square. If you only have 72 dots in that square - verses 300 dots, you're going to get a low quality print. The more information (dots) you have in the square, the cleaner and more details it will print.
The term resolution is mainly used to describe monitors, printers, and bit-mapped graphic images. Is basically referred to the sharpness and clarity of an image. The resolution in the printers, monitors, scanners, and other Input /Output devices is classified as high resolution, medium resolution, or low resolution. The grade of the resolution is constantly changing as the technology improves.
